The effect of heat treatment on toughness and wear resistance of Fe-Cr-C-Nb alloys / Uticaj termičke obrade na žilavost i otpornost na habanje Fe-Cr-C-Nb legura
(Savez inženjera metalurgije Srbije, Beograd, 2008)
Alloying with niobium improves the mechanical properties of the high chromium irons. The alloy containing appriximately 3 %Nb gives the best compromise between wear resistance and toughness. These properties were improved ...
Alkali-lead deposits of lead refinery 'Trepča' and their influence on Ibar's waters / Alkalno-olovne deponije rafinerije olova 'Trepča' i njihov uticaj na vode Ibra
(Naučno-stručno društvo za zaštitu životne sredine Srbije - Ecologica, Beograd, 2009)
Besides lead as basic metal, flotation lead concentrates contain several accompanied metals, such as: copper, zinc, iron, antimony, silver, gold, bismuth and arsenic. Raw lead and slag are obtained by agglomeration roasting ...
Electrodeposition of Ni-Mo alloy coatings and their characterization as cathodes for hydrogen evolution in sodium hydroxide solution
(Elsevier, 2008)
The hydrogen evolution reaction on the electrodeposited Ni-Mo alloy coatings, as well as their electrochemical properties in the NaOH solutions, have been investigated by the polarization measurements, cyclic voltammetry ...
Structural characteristics of bright copper surfaces
(Journal of Electroanalytical Chemistry, 2001)
In this work, the structures of copper surfaces polished mechanically and polished both mechanically and electrochemically, as well as copper coatings obtained in the presence of basic and top brightening addition agents ...
PZT ceramics obtained from mechanochemically synthesized powders
(Kluwer Academic Publ, Dordrecht, 2003)
PZT ceramics were obtained from the mechanochemically synthesized powders. Milling and sintering conditions were optimized based on results of density measurements, as well as on microstructural and electrical characterization. ...

izvora energije. Potencira se neophodnost razvoja novih ...
Spectrophotometric study of the anodic corrosion of Ti/RuO2 electrode in acid sulfate solution
(Elsevier Ltd., 2004)
Electrochemical properties of RuO2-based electrode, particularly the oxygen evolution and anodic dissolution of RuO2 have been investigated in 0.5 mol dm-3 H2SO4 solution by means of polarization measurements and product ...
Preparation and characterization of iron(III) phosphate-oxalate using 1,2-diaminopropane as the structure-directing agent
(Elsevier, Amsterdam, 2002)
Iron(III) phosphate-oxalate (FePO-DAP) crystallizes from a clear solution containing 1,2-diaminopropane (DAP) and oxalic acid at 120 degreesC under hydrothermal conditions. Doubly protonated DAP is present inside a large ...
