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 ...
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 ...
Integrated procedure for recycling and valorization of useful components from secondary raw materials based on hard metals
(Savez inženjera metalurgije Srbije, Beograd, 2017)
Wide application of hard metals requires increased consumption of their constituents. Their high cost and scarcity impose the need for finding new, both ecologically and economically justified ways for their production. ...
