摘要：

The preparation of binary Ti-Cr alloys was achieved by magnetron sputtering using a titanium target with small chromium disks on it. The alloys containing 37-73 at% Cr were amorphous. Amorphous Ti-Cr alloys were spontaneously passive showing significantly lower corrosion rates in comparison with those of titanium and chromium metals in 1 M and 6 M HCl solutions. XPS analysis revealed that air-formed films and passive films on the Ti-Cr alloys were composed of a chromium-titanium oxyhydroxide rather than a mixture of chromium and titanium oxyhydroxides. The passive chromium-titanium oxyhydroxide film was more protective, stable and resistant against depassivation in comparison with passive films on chromium and titanium.
