AB  - The main aim of this paper is to present the results of the morphological and chemical changes on the surface of a ceramic sample irradiated by the Nd:YAG laser. The tested sample is a part of an aqueduct tile, originating from the archaeological site of Yazd, Iran. The laser irradiation effects were studied as a function of the number of laser pulses and laser fluences around and over the damage threshold. The obtained modifications were investigated because these are essential in laser cleaning of aqueduct ceramics. The Nd: YAG laser with a wavelength, lambda, of 1064 nm and full width at half maximum (FWHM) pulse, tau, of 150 ps has been used for the surface treatment. The ceramic surface morphology modifications, induced by laser, were characterized by a scanning electron microscope (SEM), while the composition was examined by energy-dispersive (EDX) and X-ray fluorescence (XRF) spectroscopy. The results show that there are significant differences depending on the applied laser fluences and whether the surface is glazed or not.

AB  - This paper presents the results of 3D numerical flow simulation in the ventilation mill (VM) and air mixture channel (AMC) of Kostolac B power plant, where a centrifugal separator with adjustable blade angle is used. Numerical simulations of multiphase flow were performed using the Euler-Euler and the Euler-Lagrange approach of the ANSYS FLUENT software package. The geometry of the numerical model was almost identical to the VM and AMC of Kostolac B, except for the smallest details. An unstructured tetrahedral grid, consisted of almost three million cells, was generated. The main contribution of this paper is the original analysis of the influence of centrifugal separator (CFS) geometry modification on the coal powder distribution at the horizontal burners. The modification of the blade angle, blade shape, and vertical position of the separator and its effect on the coal powder distribution at the burners were analyzed and are published for the first time. Results of the numerical simulations were compared with the measurements and can be used in modifying the separator geometry and position to obtain optimal distribution of the pulverized coal at the burners. Application of these results, obtained by numerical methods, ensures significant savings in time and money, in the process of finding the optimal geometry of CFS.

AB  - This paper presents the results of the laser cleaning effects on textile samples with corroded metallic threads. In many museum collections, there are textile exhibits like uniforms, national costumes, flags and home textile, embroidered with metallic threads. Corrosion of metal threads is one of the most common problems that damage embroidered items. In the practice, the application of conventional cleaning methods rarely gives the expected results, and the implementation of laser technology was the next step for corrosion products cleaning. The Nd: YAG laser was used to clean the corrosion of embroidered items from a museum study collection. The effects on the laser irradiated zones were investigated by optical and SEM microscopy and the EDX analysis. The laser irradiation process parameters of the metal threads corrosion.

A considerable attention has been given to the characteristics of

tion for the desalination process. The procedures for cleaning the 
surface before the application of protective coatings and the appli-
cation of chemicals that transform rust into stable compounds we-
re discussed. As protective coatings, different types of organic co-
atings plated on well-prepared steel surfaces were used and so-
metimes special types of waxes as well. This paper presents the

AB  - The degree of preservation of iron artifacts depends on the type of underground environment and the type of corrosion products formed on their surface. This paper analyses the conditions of an archaeological find made of iron and originating from the Roman period and belonging to the collections of the Museum of Science and Technology in Belgrade. The radiographic method has been used to determine the quantity of non-corroded metal as well as to determine the presence of cracks and other defects in the artefact. The composition of the corrosion products has been analyzed by the X-ray diffraction method (XRD). In addition to iron corrosion products (goethite α-FeO(OH) and magnetite Fe3O4), the presence of a significant quantity of akaganeite β-Fe8O8(OH)8Cl1.35, has been noticed on the artifact. The content of chloride, sulphate and other ions in the corrosion products has been determined by ion chromatography (IC). The analyses have pointed to the necessity of having artifacts treated in adequate solutions immediately after their excavation in order to eliminate chloride and sulphate anions. The aim of this paper is to determine the type of corrosion products and their influence on the corrosion behavior of an archaeological artefact.

AB  - This paper analyzes the state of the French Cannon 75/27 model 1911. Déport made of steel. The amount of non-corroded materials, the presence of cracks and other defects in the cannon were determined by the radiographic method. The composition of corrosion products were analyzed using diffraction of X-rays (XRD method). In addition to goethite α-FeO(OH), lepidocrocite γ-FeO(OH) and magnetite Fe3O4, the presence of akaganeite was observed in the corrosion products, β-Fe8O8(OH)8Cl1.35 which indicates the accelerated corrosion of the base metal. With the ion chromatography method, the content of chloride, sulphate and other ions in corrosion products were examined. On the basis of conducted experiments, it can be concluded that it is necessary to treat the cannon in appropriate solutions, as quickly as possible, to remove chloride and sulphate ions.

Za određivanje količine nekorodiralog materijala, prisustva prslina i drugih defekata u eksponatu korišćena je radiografska metoda. Sastav korozionih produkata je analiziran metodom difrakcije rendgenskih zraka (XRD). Pored getita, α-FeO(OH), lepidokrokita, γ-FeO(OH) i magnetita, Fe3O4, na eksponatima je uočeno prisustvo akaganita koje ukazuje na aktivnu koroziju osnovnog metala. Metodom jonske hromatografije je određen sadržaj hloridnih i drugih anjona u korozionim produktima. Na osnovu izvedenih eksperimenata nameće se zaključak o neophodnosti tretmana topa u odgovarajućim rastvorima što je moguće pre u cilju uklanjanja hloridnih i drugih koroziono aktivnih jona.

abstract = "This paper analyzes the state of the French Cannon 75/27 model 1911. Déport made of steel. The amount of non-corroded materials, the presence of cracks and other defects in the cannon were determined by the radiographic method. The composition of corrosion products were analyzed using diffraction of X-rays (XRD method). In addition to goethite α-FeO(OH), lepidocrocite γ-FeO(OH) and magnetite Fe3O4, the presence of akaganeite was observed in the corrosion products, β-Fe8O8(OH)8Cl1.35 which indicates the accelerated corrosion of the base metal. With the ion chromatography method, the content of chloride, sulphate and other ions in corrosion products were examined. On the basis of conducted experiments, it can be concluded that it is necessary to treat the cannon in appropriate solutions, as quickly as possible, to remove chloride and sulphate ions., U ovom radu analizirano je stanje francuskog topa 75/27 model 1911 Déport izrađenog od čelika. Za određivanje količine nekorodiralog materijala, prisustva prslina i drugih defekata u eksponatu korišćena je radiografska metoda. Sastav korozionih produkata je analiziran metodom difrakcije rendgenskih zraka (XRD). Pored getita, α-FeO(OH), lepidokrokita, γ-FeO(OH) i magnetita, Fe3O4, na eksponatima je uočeno prisustvo akaganita koje ukazuje na aktivnu koroziju osnovnog metala. Metodom jonske hromatografije je određen sadržaj hloridnih i drugih anjona u korozionim produktima. Na osnovu izvedenih eksperimenata nameće se zaključak o neophodnosti tretmana topa u odgovarajućim rastvorima što je moguće pre u cilju uklanjanja hloridnih i drugih koroziono aktivnih jona.",

AB  - One artefact of the archaeological cultural heritage from Roman period (IV century) that was 
found near Šabac in Serbia, was analysed. In corrosion products of the artefact (knife), 
dominant phases were goethite (α-FeOOH) and magnetite (Fe3O4). Presence of these types 
of corrosion products explains a good preservation of the base metal (iron) over the centuries 
and stability after excavation. Also, the less stable lepidocrocite (γ-FeOOH) and the phases 
that come from rocks and land surrounding environment (like SiO2) were identified in the 
corrosion products. Phases containing chloride ions (i.e. akaganéite) have not been detected 
in the corrosion products. This indirectly indicates that the amount chloride ions were rather 
low in underground exploitation conditions.
