Abstract

This paper presents the results of investigations on electrolytic polishing and anodic passivation of Ti-15Mo alloy. The influence of chemical composition of the bath used in electrolytic polishing and anodic passivation process on the morphology, wettability and corrosion resistance of the electrochemically modified vanadium-free Ti-15Mo alloy was presented. The electropolishing process was carried out in a solution containing: sulphuric acid, ethylene glycol, ammonium fluoride and oxalic acid. Moreover, the anodic oxidation process was carried out in a 1.0 M H2SO4, 1.0 M H3PO4 and 0.5 M solution of K2SiO3 and 5 g/dm3 KOH. It was found that the electrolytic polishing and anodic passivation led to significant improvement of the surface morphology. The electrolytic polishing and anodic passivation of Ti-15Mo improved corrosion resistance of the alloy in contact with of Ringer's physiological solution. The samples anodized at 100 V in 1.0 M H3PO4 presented the highest corrosion resistance.
