The effect of cooling rate of slag from primary copper production in the valorization of copper in the flotation process
(Savez inženjera metalurgije Srbije, Beograd, 2015)
Technological procedure of slow cooling slag from primary copper production is applied in the purpose of copper recovery in the level of 98.5% to blister. This technological procedure is divided into two phases, first slow ...
The characterization of ternary Zn-Ni-Co alloy coatings electrochemically deposited on steel from sulfate solution / Karakterizacija prevlaka trojnih legura Zn-Ni-Co na čeliku elektrolitički taloženih iz sulfatnog rastvora
(Engineering Society for Corrosion, Belgrade, Serbia, 2016)
In this work the electrochemical deposition of ternary Zn-Ni-Co alloy coatings on steel from sulfate, additive-free electrolyte, was investigated. The ratio of metal cations [Co2+]/[Ni2+] in the plating solution was analysed, ...
Development of an effective method for internal pipeline corrosion control in the presence of CO2 / Razvijanje efikasne metode zaštite cevovovoda od unutrašnje korozije u prisustvu CO2
(Engineering Society for Corrosion, Belgrade, Serbia, 2016)
This paper reports on progress in developing an effective method for internal pipeline corrosion control in the presence of CO2. The inhibition effect of talloil diethylenetriamine imidazoline (TOFA/DETA imidazoline) on ...
Fluoride ion adsorption onto Al-alginate particles / Adsorpcija fluoridnih jona na Al-alginatnim česticama
(Engineering Society for Corrosion, Belgrade, Serbia, 2017)
Fluoride ions are increasingly present in the groundwater mainly due to the anthropogenic activity. On the other hand, increased awareness of harmful effects caused by high concentrations of F-in drinking water, leads to ...
CO tolerant Pt/Ru0.7Ti0.3O2 nanocatalyst for hydrogen oxidation reaction / Pt/Ru0,7Ti0,3O2 kao nanokatalizator za oksidaciju vodonika i njegova tolerancija na CO
(Engineering Society for Corrosion, Belgrade, Serbia, 2018)
The oxidation of pure H2 and H2/CO mixture (100 ppm CO) was investigated on Pt nanocatalyst supported on Ru0.7Ti0.3O2 (Pt /Ru0.7Ti0.3O2) by linear sweep voltammetry at a rotating disc electrode in 0.1 M HClO4. The results ...
Kinetics of barite reduction from refractory barite-sulphide ore
(Savez inženjera metalurgije Srbije, Beograd, 2016)
Refractory sulphide-barite ore was reduced with carbon in order to release lead, zinc, and copper sulphide from barite-pyrite base. Mineralogical investigations showed that due to the complex structural-textural relationships ...
The comparative study of the corrosion stability of Zn-Ni-Co alloy coatings deposited from chloride and sulphate baths / Uporedna analiza korozione stabilnosti prevlaka Zn-Ni-Co legura elektrohemijski taloženih iz hloridnih i sulfatnih rastvora
(Engineering Society for Corrosion, Belgrade, Serbia, 2017)
The ternary Zn-Ni-Co alloy coatings were electrodeposited on steel from chloride and sulphate baths. The deposition was carried out galvanostatically at different current densities at ambient temperatures from additives ...
Tailoring the corrosion resistance of Zn-Mn coating by electrodeposition from deep eutectic solvents / Poboljšanje korozione postojanosti Zn-Mn prevlake, elektrohemijskim taloženjem iz dubokih eutektičkih smeša
(Engineering Society for Corrosion, Belgrade, Serbia, 2018)
Well adhered, homogenous coatings were obtained from deep eutectic solvents (DES) based on choline chloride and urea, at current densities up to 20 mA cm-2. The coatings' morphology was analyzed by atomic force microscopy, ...
Hardness and assessment of adhesion of monolayer and multilayer nickel thin films electrochemically deposited on silicon substrates with and without the ultrasonic agitation / Tvrdoća i procena adhezije jednoslojnih i višeslojnih tankih filmova nikla elektrohemijski deponovanih na silicijumskim podlogama sa i bez ultrazvučnog mešanja
(Academy of Criminalistic and Police Studies, Belgrade, 2019)
Composite systems of monolayer and multilayer nickel films electrochemically deposited on single crystal (100)-oriented silicon wafers were fabricated with and without the ultrasonic agitation. The hardness and adhesion ...
Simulation of velocity profile inside turbulent boundary layer
(Association of Metallurgical Engineers of Serbia, 2020)
The second-order differential equation with a general polynomial solution [1], is adapted for simulation of complex velocity profile inside the turbulent boundary layer. Consequently, the simulation strategy is suggested.
