Research Abstract

Although well known for their superior resistance to corrosion, titanium and titanium alloys are unable to withstand discoloration in clinically. This study revealed the corrosion behavior of titanium alloys with electrochemical measurement, discoloration, dissolution, EQCM and EIS analysis. The results confirm that corrosion of titanium takes place in acidulated fluoride- or alkaline peroxide-containing solution, and discoloration mainly results from peroxide-induced oxidation in acidulated peroxide containing solution. The addition of chromium suppresses corrosion of titanium alloys.
