AB  - In this study, corrosion protection efficiency of undoped epoxy and epoxy coating doped with cerium on aluminum alloy AA6060 is evaluated over prolonged exposure to 3wt% NaCl solution by electrochemical impedance spectroscopy (EIS). Different amounts of Ce(NO3)(3) are added into the epoxy suspension used for the cataphoretic deposition. Suspension stability is characterized by zeta potential and particle size values. Water content and thermal stability of the coatings were determined by thermogravimetric analysis. Insufficient corrosion stability, very close to that of undoped epoxy, is revealed for the coating with 1mM Ce. Higher cerium doping contributes to a significant increase in corrosion stability (2-3 orders of magnitude greater charge-transfer resistance). Epoxy coating doped with 5mM Ce displays a pronounced self-healing ability and the best corrosion protection and adhesion, owing to evenly distributed cerium precipitates on the aluminum surface. In the case of 10mM Ce-doped coating, the formation of Ce clusters and higher porosity causes a certain lowering of the protective ability. EIS measurements on epoxy coating with artificial defect confirm these findings.

AB  - Protective coatings should provide good barrier to ingress of corrosive species, sufficient adhesion to the substrate as well as good compatibility with additional top coats. The presence of pigments and/or functional agents in the coating composition could be beneficial in the corrosion protection. The doping with rare earth elements, like cerium, has shown to enhance the corrosion stability of organic coatings due to their self-healing properties. In this work cerium doped nanometric epoxy primers were deposited cataphoretically with different amounts of cerium nitrate (1, 5 and 10 mM) with the aim of optimizing the cerium content in the epoxy emulsion with respect to adhesion and corrosion stability of deposited primer coating. Cerium-free epoxy coating was also analyzed as a reference. The long term protection was evaluated in the chloride environment (3 wt.%NaCl) using electrochemical impedance spectroscopy (EIS) and polarization measurements. Coatings were also analyzed by scanning electron microscopy (SEM) coupled with EDX, Fourier transform infrared spectroscopy and thermogravimetric measurements. Size and zeta potential of epoxy emulsion were measured by dynamic light scattering and Laser Doppler velocimetry. Adhesion was determined both by a standardized pull-off method and by swelling in N-methyl pyrrolidone. The ceria content, as well as its distribution in the epoxy coating, was determined by SEM cross-sectional analysis. The homogeneity of epoxy coatings was evaluated and related to corrosion stability. The results showed that cerium-doping can promote the formation of compact epoxy coatings with enhanced protectiveness in the early stage of immersion in the corrosive media. Increased barrier properties of epoxy primers suggest good compatibility of ceria particles with polymeric epoxy layer. However, zeta potential measurements indicated that higher amounts than 10 mM Ce(NO3)3 added into the epoxy emulsion resulted in unstable emulsion. The water content in the epoxy coatings and their thermal stability were also determined. In addition, a detailed EIS study was undertaken to follow the evolution of corrosion stability of all samples with time of exposure to corrosive media. It was shown that all examined ceria containing epoxy emulsions resulted with the enhanced adhesion and corrosion stability of epoxy primers. However, the smallest loading of 1 mM showed only improvement during the initial exposure to NaCl solution. EIS and polarization measurements confirmed that higher ceria loadings also provide long term protection in chloride solution.The optimal ceria content in the epoxy emulsion, with respect to adhesion strength, thermal stability and long-term corrosion stability of protective systems was 10 mM.

AB  - Ce-based conversion coatings (CeCCs) are a promising alternative to toxic chromate coatings on the metal substrates. In this work the CeCCs were electrodeposited on aluminium alloy AA6060 from aqueous solution of Ce(NO3)(3) at different potentials (-0.95 V, -1.2 V and -1.4V). Effect of deposition potential and post-treatment in the phosphate solution on morphology and protective properties of CeCCs with top cataphoretic epoxy coating was studied. To assess the differences between the protective systems, originating from the different CeCCs pre-treatments, electrochemical impedance spectroscopy (EIS), polarization measurements, AFM and SEM/EDS analysis were used. The EIS study was undertaken to follow the evolution of corrosion behaviour of epoxy coating/CeCCs protective systems over prolonged time of exposure to the chloride environment (3 wt.% NaCl). Results suggest significantly improved corrosion stability of epoxy coating on AA6060 with as-deposited CeCCs sub-layers with respect to the same epoxy coatings with phosphate post-treated CeCCs. The far best protective properties, i.e., the greatest value of pore resistance and the lowest value of corrosion current density were provided by the epoxy coating/CeCC protective system with CeCC deposited at -1.2V and without post-treatment.

AB  - Among potential replacements for chromates, cerium-based conversion coatings (CeCCs) have been identified as leading candidates, showing a good promise as environmentally compliant corrosion inhibitors on Al alloys. In this work, CeCCs were synthesized on M6060 by electrolytic deposition (ELD), a well-suited method for the fabrication of films with controllable properties, at low processing temperature and cost. The CeCCs were deposited at room temperature from Ce(NO3)(3) solution, applying different cathodic potentials (-1.1, -1.4 and -1.6 V vs. SCE) for different deposition times between 5 and 20 min. Structural, morphological and compositional properties of the films were characterized by X-ray diffraction, Raman spectroscopy and scanning electron microscopy coupled with energy dispersive spectroscopy. Ceria films were nanostructured, exhibiting a cubic fluorite structure. From corrosion perspective, the quality of CeCCs was evaluated in 0.5 M NaCI solution via electrochemical impedance spectroscopy and linear sweep voltammetry. As shown, the coating corrosion quality is the interplay between deposition potential and deposition time. The highest potential led to highly cracked films of poor adherence, even at the shortest deposition time, which disqualified them from any corrosion protection application. The lowest potential (-1.1 V) produced crack-free coatings, but longer times ( gt = 10 min) were needed to provide the protective layer formation. The best corrosion protection offered CeCCs prepared at -1.4 V. The highest R-p (582 k Omega cm(2)) and the smallest CPE (12.6 . 10(-6) s(n) Omega(-1) cm) were obtained at 20 min deposition time. However, from economical point of view, 10 min deposition is a promising choice. These CeCCs also improved pitting corrosion resistance owing to homogeneous microstructure and sufficient thickness.

AB  - The influence of different types of conversion phosphate coatings on the corrosion stability of top powder polyester coating on steel was investigated. The morphology of phosphate coatings was investigated using scanning electron microscopy (SEM), composition by energy dispersive X-ray spectroscopy (EDS) and surface coverage by voltametric anodic dissolution (VAD) technique. The corrosion stability of polyester coating on steel pretreated by phosphate coatings was investigated by electrochemical impedance spectroscopy (EIS). It was shown that small crystal nuclei of iron-phosphate coating have sporadically emerged on the steel substrate while zinc-phosphate coating had more compact structure with better surface coverage. After prolonged exposure, there was a significant decrease in Rp values for polyester/zinc-phosphate protective system, as a result of the disbondment of polyester coating, while Rp values for polyester coating on steel pretreated with iron-phosphate coating remained almost unchanged, pointing to a greater stability of this protective system.

AB  - In this study, the effect of deposition time and concentration of NaNO2 in the phosphate bath on the surface morphology of iron-phosphate coatings on low carbon steel was investigated using scanning electron microscopy (SEM) and atomic force microscopy (AFM). The composition of ironphosphate coatings was determined using energy dispersive X-ray spectroscopy (EDS) and X-ray diffraction (XRD), while surface coverage was evaluated by the voltammetric anodic dissolution (VAD) technique in the borate solution. The addition of NaNO2 to the phosphate bath significantly increased the surface coverage since better packed crystals of smaller size, which favour the phosphate nucleation, were obtained. It was also shown that prolonged deposition time increased the surface coverage, coating roughness and crystal size in the lateral direction, altering also the crystal shape from large platelets non-uniformly distributed on the steel surface during the initial time to better packed laminated and needle-like structures during prolonged exposure.
AB  - U ovom radu je, primenom skenirajuće elektronske mikroskopije (SEM) i mikro- skopije međuatomskih sila (AFM), ispitivan uticaj vremena taloženja i koncentracije NaNO2 u rastvoru za fosfatiranje na morfologiju gvožđe-fosfatnih prevlaka na nisko-ugljeničnom čeliku. Sastav gvožđe–fosfatnih prevlaka je određen primenom energetske disperzione atomske analize (EDS) i difrakcijom H-zraka (XRD), dok je pokrivenost površine određivana anodnim rastvaranjem u boratnom rastvoru primenom linearne voltametrije (VAD). Pokazano je da dodatak NaNO2 u rastvoru za fosfatiranje značajno povećava pokrivenost površine čelika, jer se formiraju bolje pakovani kristali, manje veličine. Duže vreme taloženja takođe povećava pokrivenost površine, kao i hrapavost prevlake i širinu kristala. Oblik kristala se tokom dužeg vremena taloženja menja od kristala u obliku većih ploča neuniformno raspoređenih na površini čelika, ka bolje pakovanim laminarnim i igličastim kristalima.

abstract = "In this study, the effect of deposition time and concentration of NaNO2 in the phosphate bath on the surface morphology of iron-phosphate coatings on low carbon steel was investigated using scanning electron microscopy (SEM) and atomic force microscopy (AFM). The composition of ironphosphate coatings was determined using energy dispersive X-ray spectroscopy (EDS) and X-ray diffraction (XRD), while surface coverage was evaluated by the voltammetric anodic dissolution (VAD) technique in the borate solution. The addition of NaNO2 to the phosphate bath significantly increased the surface coverage since better packed crystals of smaller size, which favour the phosphate nucleation, were obtained. It was also shown that prolonged deposition time increased the surface coverage, coating roughness and crystal size in the lateral direction, altering also the crystal shape from large platelets non-uniformly distributed on the steel surface during the initial time to better packed laminated and needle-like structures during prolonged exposure., U ovom radu je, primenom skenirajuće elektronske mikroskopije (SEM) i mikro- skopije međuatomskih sila (AFM), ispitivan uticaj vremena taloženja i koncentracije NaNO2 u rastvoru za fosfatiranje na morfologiju gvožđe-fosfatnih prevlaka na nisko-ugljeničnom čeliku. Sastav gvožđe–fosfatnih prevlaka je određen primenom energetske disperzione atomske analize (EDS) i difrakcijom H-zraka (XRD), dok je pokrivenost površine određivana anodnim rastvaranjem u boratnom rastvoru primenom linearne voltametrije (VAD). Pokazano je da dodatak NaNO2 u rastvoru za fosfatiranje značajno povećava pokrivenost površine čelika, jer se formiraju bolje pakovani kristali, manje veličine. Duže vreme taloženja takođe povećava pokrivenost površine, kao i hrapavost prevlake i širinu kristala. Oblik kristala se tokom dužeg vremena taloženja menja od kristala u obliku većih ploča neuniformno raspoređenih na površini čelika, ka bolje pakovanim laminarnim i igličastim kristalima.",

AB  - Dip-immersion is a simple and cost-effective method for the preparation of Ce-based conversion coatings (CeCCs), a promising alternative to toxic chromate coatings, on metal substrates. In this work, CeCCs were prepared on Al-alloy AA6060 from an aqueous solution of cerium chloride at room temperature. The effect of immersion time and post-treatment in phosphate solution on the microstructure and corrosion properties of the coatings was studied. The longer the immersion time was, the thicker but more nonhomogeneous and cracked were the CeCCs. The post-treatment contributed to a sealing of the cracks, as proven by an increase in the corrosion resistance compared with the as-deposited coatings. The CeCCs prepared at longer deposition times and post-treated showed much better corrosion protection than those prepared at shorter deposition times. A detailed electrochemical impedance spectroscopy (EIS) study was undertaken to follow the evolution of the corrosion behaviour of the CeCCs with time of exposure to an aggressive chloride environment (3.5 % NaCl). For the sake of comparison, the EIS properties of bare AA6060 were also investigated. Linear voltammetry was performed to complete the study. The results confirmed the formation of protective CeCCs on the surface of AA6060. However, even CeCCs prepared at longer deposition times and post-treated provided short term protection in the aggressive environment, due to the small thickness of the coating.
AB  - Nanošenje prevlaka potapanjem u rastvor je jednostavna i ekonomski prihvatljiva metoda za pripremu konverzionih prevlaka na bazi cerijuma na metalnim supstratima, koje su dobra zamena za toksične hromatne prevlake. U ovom radu prevlake na bazi cerijuma su nanesene na aluminijumsku leguru AA6060 iz vodenog rastvora cerijum-hlorida na sobnoj temperaturi. Ispitivan je uticaj vremena potapanja i uticaj naknadnog tretmana u fosfatnom rastvoru na mikrostrukturu i zaštitna svojstva dobijenih prevlaka. Dužim potapanjem su dobijene deblje ali nehomogene prevlake. Naknadni tretman je povoljno uticao na zatvaranje prskotina, što je u saglasnosti sa izmerenom većom korozionom otpornošću u poređenju sa prevlakama bez tretmana. Prevlake dobijene dužim nanošenjem su pokazale bolju korozionu zaštitu od prevlaka dobijenih kraćim nanošenjem. Koroziona stabilnost prevlaka je ispitivana u agresivnoj hloridnoj sredini (3,5 % NaCl) metodama spektroskopije elektrohemijske impedancije (SEI) i linearne voltametrije. Detaljno je praćeno koroziono ponašanje prevlaka sa vremenom delovanja korozionog agensa. Poređenja radi, SEI analiza je sprovedena i za leguru AA6060 bez prevlake. Rezultati istraživanja potvrđuju da dobijene prevlake na bazi cerijuma predstavljaju dobru korozionu zaštitu leguri AA6060. Međutim, čak i kvalitetnija prevlaka (20 min potapanja i naknadno tretirana u fosfatnom rastvoru) obezbeđuje leguri kratkoročnu zaštitu u agresivnoj sredini usled svoje male debljine.

AB  - Cerium-based conversion coatings (CeCCs) are one of the most prospective alternatives to the widely used chromate conversion coatings (CCCs) due to their anticorrosion efficiency, environmentally friendly nature and low cost. In this work, the CeCCs on AA6060 were prepared by immersion into aqueous cerium salt solutions at room temperature, and subsequently post-treated in heated phosphate solution. The effect of counter ion (nitrate and chloride) on the coating properties was studied testing CeCCs as sole or conversion layers for the top polyester coating. Since the 60 mu m thick polyester coating was applied, an artificial defect of 0.8 mm hole was introduced to faster assess the differences between pretreatments. The system with CCC pretreatment was used as reference. Corrosion properties were investigated in 0.5 M NaCl solution by electrochemical impedance spectroscopy while the adhesion strength was measured by NMPR (N-methyl-2-pyrrolidone) and pull-off tests. As shown, the post-treated chloride-based CeCC offered better protection than crack-free thin nitrate-based CeCC, when used as sole coatings. On the other hand, it was brought to evidence that in combination with top powder polyester coating, the CeCC deposited from nitrate solution exhibited better protection compared to protective system pretreated with chloride-based one. Excellent polyester coating adhesion was found independently on aluminium surface pretreatment.

AB  - The influence of deposition temperature and concentration of NaNO2 in the phosphating bath on the surface morphology and coverage of iron-phosphate coatings on low carbon steel was investigated. The phosphate coatings were chemically deposited on steel from phosphate bath at different temperatures (30-70 degrees C) and with the addition of different amounts of accelerator, NaNO2 (0.1, 0.5 and 1.0 g dm(-3)). The morphology of phosphate coatings was investigated using scanning electron microscopy (SEM) and atomic force microscopy (AFM). The composition of iron-phosphate coatings was determined using energy dispersive X-ray spectroscopy (EDS) and X-ray diffraction (XRD). Surface coverage was evaluated by the voltammetric anodic dissolution (VAD) technique. It was shown that the increase in temperature of the NaNO2-free phosphating bath up to 70 degrees C caused an increase in surface coverage. The addition of NaNO2 in the phosphating bath significantly increased the surface coverage of phosphate coatings deposited at temperatures lower than 50 degrees C. The phosphate crystals were of laminated and needle-like structures for deposits obtained at temperatures lower than 50 degrees C, while at higher temperatures needle-like structure was transformed to laminated structure. The increase in NaNO2 concentration in the phosphating bath from 0.1 to 1.0 g dm(-3) did not significantly increase the surface coverage, but decreased the crystals size, consequently favouring the phosphate nucleation and better packing of the crystals.

AB  - The influence of steel surface pretreatment with different types of iron-phosphate coatings on the corrosion stability and adhesion characteristics of polyester coatings on steel was investigated. The phosphate coating was chemically deposited either from the simple novel plating bath, or with the addition of NaNO2, as an accelerator in the plating bath. The morphology of phosphate coatings was investigated using atomic force microscopy (AFM). The corrosion stability of polyester coatings on steel pretreated by iron-phosphate coatings was investigated by electrochemical impedance spectroscopy (EIS) in 3% NaCl solution, while "dry" and "wet" adhesion were measured by a direct pull-off standardized procedure. It was shown that greater values of pore resistance. R-p, and smaller values of coating capacitance of polyester coating, C-c, on steel pretreated with iron-phosphate coating were obtained, as compared to polyester coating on steel phosphated with accelerator, and on the bare steel. The surface roughness of phosphate coating deposited on steel from the bath without accelerator is favorable in forming stronger bonds with polyester coating. Namely, the dry and wet adhesion measurements are in accordance with EIS measurements in 3% NaCl solution, i.e. lower adhesion values were obtained for polyester coating on steel phosphated with accelerator and on the bare steel, while the iron-phosphate pretreatment from the novel bath enhanced the adhesion of polyester coating on steel.

R-p, and smaller values of coating capacitance of polyester coating, C-c, on steel pretreated with iron-phosphate coating were obtained, as compared to polyester coating on steel phosphated with accelerator, and on the bare steel. The surface roughness of phosphate coating deposited on steel from the bath without accelerator is favorable in forming stronger bonds with polyester coating. Namely, the dry and wet adhesion measurements are in accordance with EIS measurements in 3% NaCl solution, i.e. lower adhesion values were obtained for polyester coating on steel phosphated with accelerator and on the bare steel, while the iron-phosphate pretreatment from the novel bath enhanced the adhesion of polyester coating on steel.",

AB  - The iron phosphate layers on the low carbon steel surface slows steel corrosion in aggressive environments. The quality of the iron phosphate layer depends on the fraction of the total surface area covered by phosphate coating. Various factors affect this coverage fraction, in particular the composition of the deposition bath, bath temperature and additives used in the electrolyte. In this study phosphating was carried in the phosphate solution (NaOH + H3PO4 + NaNO2, pH 3.8) at different temperatures (30-70oC). The porosity of phosphate coatings on low carbon steel was determined using VAD technique in the borate solution. Surface morphology of the steel was studied using SEM and AFM technique. Anodic polarization showed that phosphate coatings formed on the steel surface resulted in the decrease of the steel dissolution rate. This effect of the phosphate coatings was more pronounced for coatings deposited at higher temperatures of phosphate solution. The decrease in the steel dissolution rate is caused by the decrease of coating porosity. The addition of NaNO2 in the phosphate solution significantly decreased phosphate coating porosity. The lowest porosity of phosphate coating (35.1%), for deposition time of 5 min, was obtained with 1.0 g dm-3 NaNO2 in the phosphate solution, at 50oC. The study of the phosphate coatings morphology showed that coating was evenly dispersed on the whole steel surface. There were two characteristic forms of phosphates present: laminated structure with needle-like forms. The average concentration of specific elements in the phosphate coatings were: oxygen 37.6%, phosphor 3.26% and iron 59.14%.

AB  - One of the most important factors in corrosion prevention by protective coatings is the coating adhesion loss under environmental influence. Thus, adhesion strength is often used when characterizing protective properties of organic coatings on a metal substrate. In order to improve the adhesion of organic coating the metal substrate is often pretreated in some way. In this work, the adhesion of polyester coatings on differently pretreated aluminium surface (by anodizing, with and without sealing, by phosphating and by silane film deposition) was examined. The dry and wet adhesion of polyester coatings were measured by a direct pull-off standardized procedure, as well as indirectly by NMP test. It was shown that under dry test conditions all polyester coatings showed very good adhesion, but that aluminium surface pretreated by silane film showed superior adhesion. The overall increase of wet adhesion for polyester coating on aluminium pretreated by silane film was maintained throughout the whole investigated time period. The different trends in the change of adhesion of polyester coatings were observed for different aluminium pretreatments during exposure to the corrosive agent (3% NaCl solution). The highest adhesion reduction was obtained for polyester coating on aluminium pretreated with phosphate coating. The corrosion stability of polyester coated aluminium was investigated by electrochemical impedance spectroscopy in 3% NaCl solution. The results confirmed good protective properties of polyester coating on aluminium pretreated with silane film, i.e. greater values of pore resistance and smaller values of coating capacitance were obtained in respect to other protective systems, whereas charge-transfer resistance and double-layer capacitance were not measurable during 2 months of exposure to a corrosive agent.

AB  - The influence of hot-dip galvanized steel (HDG) surface pretreatment with phosphate coatings on the corrosion stability and adhesion characteristics of epoxy coatings electrodeposited on HDG steel was investigated. Phosphate coatings were deposited on hot-dip galvanized steel from baths with different concentrations of NaF (0.1, 0.5 and 1.0 g dm(-3)) and at different temperatures (50, 65 and 80 degrees C). The influence of fluoride ion concentration in the phosphating bath, as well as the deposition temperature of the bath, on the adhesion characteristics and corrosion stability of epoxy coatings on phosphated HDG steel was investigated. The dry and wet adhesions were measured by a direct pull-off standardized procedure, as well as indirectly by NMP test, while corrosion stability was investigated by electrochemical impedance spectroscopy (EIS). It was shown that under dry testing conditions all the samples exhibited very good adhesion. However, the different trends of adhesion loss of different protective systems during exposure to corrosive agent (3% NaCl solution) were observed.
