Cavitation of refratory samples based on talc and domestic zeolite / Ispitivanje vatrostalnih uzoraka na bazi talka i domaćeg zeolita na dejstvo kavitacije
(Savez inženjera i tehničara Srbije, Beograd, 2018)
Using domestic zeolite from Igroš as row material for ceramic samples for application in condition of cavitation erosion. Samples based on talc with 15 % of zeolite, from Igroš, sintered at 1200oC were used in this ...
Oxygen reduction reaction on electrochemically deposited sub-monolayers and ultra-thin layers of Pt on (Nb-Ti)2AlC substrate / Reakcija redukcije kiseonika na elektrohemijski istaloženim tankim slojevima platine na (Nb-Ti)2alc nosaču
(Engineers Society for Corrosion, 2022)
Catalytic activity towards the oxygen reduction reaction (ORR) in 0.5 M H2SO4 was investigated at sub-monolayers and ultra-thin layers (corresponding to 10, 30 and 100 monolayers, (MLs)) of Pt electrochemically deposited ...
Characterization of NiAl layers deposited by atmospheric plasma spray (APS) / Karakterizacija NiAl slojeva deponovanih atmosferskim plazma sprejom (APS)
(Engineering Society for Corrosion, Belgrade, Serbia, 2020)
In this paper analyzed were the mechanical properties and microstructure of the Ni30Al coating layers deposited using atmospheric plasma spray (APS). For deposition of the coating applied was a composite Ni30wt.% Al powder, ...
