Abstract

Oxidation of titanium and its alloys at a high temperature for a short time was carried out with gold and platinum predeposition. Preliminary results show gold can improve the quality of the oxide and the bond strength of the metal/oxide. Gold predeposition leads to a thicker oxide layer and more absorption of oxygen. Further investigations show that the existence of the thin gold layer is beneficial for the outward diffusion of titanium during oxidation at 800C and 850C.
