Abstract

Investigations on the surface modification of the Ti-6Al-4V alloy by plasma electrolytic oxidation are reported here. The oxidation process was carried out in a solution containing a zirconium silicate (ZrSiO4) suspension and sodium hydroxide (NaOH). Anodising was realised at voltages in a range from 100 V to 250 V. It was found that the morphology of the sample surface did not change during the oxidation of the alloy at 100 V. Application of voltages higher than 100 V led to the incorporation of zirconium silicate into the formed oxide layer and to significant changes of the surface morphology.

Abstract

Investigations of voltammetry zirconium deposition from DMSO solution on different substrates were taken. It was found that this is multi-electron process proceeding in a few stages. Moreover, zirconium layers were obtained on titanium, copper stainless steel and nickel. Obtained deposit was in form of white powder, which immediately was oxidized to ZrO2 in the presence of air.
