The oxidation behavior of Ti50Cu50 metallic glass has been investigated. When the oxide is in amorphous state blow the glass transition temperature, the diffusion rate of Ti ion from the matrix controls the growth rate of the oxide layer. With the increase of thickness, the amorphous oxide is crystallized into TiO2, which grows in inward direction by diffusion of oxygen ion through the oxide layer. Above the crystallization temperature, fast diffusion of Ti and oxygen ions through columnar grain boundary of TiO2 results in the formation of Ti3Cu3O underneath the oxide layer and TiO2 on the surface.
