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 ...
Influence of acidic solutions on the strain distribution in glasspolyester composite pipes subjected to internal pressure / Uticaj rastvora kiselina na raspodelu deformacija kod staklo-poliestar kompozitnih cevi istaloženih dejstvu unutrašnjeg pritiska
(Engineering Society for Corrosion, Belgrade, Serbia, 2016)
The basic subject of this paper was the determination of the strain distribution in glass-polyester composite pipes subjected to internal pressure. Firstly, the test was performed on virgin pipe segments (without the ...
PtAu catalyst with enhanced activity for formic acid oxidation / PtAu katalizator sa poboljšanom aktivnošću za reakciju oksidacije mravlje kiseline
(Engineering Society for Corrosion, Belgrade, Serbia, 2018)
PtAu systems are recognized as good catalysts for the oxidation of formic acid electrooxidation, which is investigated as a possible anodic reaction in low-temperature fuel cells. In this research, bimetallic PtAu ...

(Association of Metallurgical Engineers of Serbia, 2016)
This work presents the laboratory testing results of kinetics the oxidation process and sample processing of the sulphide polymetallic concentrate Blagojev Kamen. The aim of investigation is recovery of these types of raw ...
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 ...
Treatment of dispersed iron-bearing raw materials and modeling of the protection systems against air-pollution
(Association of Metallurgical Engineers of Serbia, 2016)
Based on the analysis of the non-standard iron-bearing raw materials treatment process and the results of real composition measurements of the flue gas, the study of hazards by identification of harmful substances that ...
Ni-pd/al(2)o(3) catalyst supported on reticulated ceramic foam for dry methane reforming
(Savez inženjera metalurgije Srbije, Beograd, 2015)
In the present study, Ni-Pd/Al2O3 catalyst supported on alpha-Al2O3 based foam was prepared and evaluated in the dry methane reforming process. Corresponding metal chlorides were deposited to the foam surface by impregnation ...
Effect of vibration on the variation of residual stresses and impact energy in butt-welded joints / Uticaj vibracija na promenu zaostalih napona i energije udara kod sučeono zavarenih spojeva
(Society for Structural Integrity and Life, Institute for Material Testing, 2012)
The effect of vibration on the variation of residual stresses in butt-welded steel plates and on the impact energy in characteristic zones of a welded joint is analysed in this paper. An important segment occurring as a ...
Influence of the fabrication process of copper matrix composites on cavitation erosion resistance
(Savez inženjera metalurgije Srbije, Beograd, 2017)
Copper matrix composites reinforced with ZrB2 particles were produced in two ways: by hot pressing (HP) and laser-sintering process. Powder mixture Cu-Zr-B was mechanically alloyed before densification processes. Variations ...
Impedance characteristics of aluminum with sol-gel ceria protective coating during the exposure to chloride corrosion agent / Impedansni odgovor aluminijuma sa zaštitnom prevlakom oksida cerijuma tokom izlaganja hloridnoj korozionoj sredini
(Engineering Society for Corrosion, Belgrade, Serbia, 2016)
Electrochemical impedance characteristics of bare Al and Al with CeO2 coating prepared sol-gel procedure from the ceria sol are investigated. The corrosion behavior is monitored during the exposure to 3 wt. % NaCl aqueous ...
