In the present study, we propose a novel approach to exploring glassy alloys with high oxidation resistance in their supercooled liquid region. The oxidation resistance of the Zr-based metallic glasses can be strongly enhanced when the glassy surface is covered by a native amorphous metal oxide film. We have investigated the effect of codoping Al and Ti into the amorphous zirconia on glass stability of the amorphous oxide by selecting Ni45Zr35-xTi20Alx quaternary metallic glass system. The thermogravimetric analysis suggests that codoping multi-components is an effective way to enhance the glass stability of the amorphous oxide film.
