Abstract : The addition of chromium to alloys of the Ti-Mo system reduces the tendency toward repassivation caused by the presence of Mo. The alloy Ti-5Mo-10Cr, in the potential range 0.15-1.2 V, has the same low corrosion rate as titanium or the alloy Ti-10Cr. At potentials above 1.2 V the corrosion rate of Ti-Mo-Cr allosy increases. With an increase in Mo content from 5 to 20% in alloys of the Ti-Cr system the corrosion rate in the range of potentials of repassivation with respect to chromium increases. After the corrosion of alloys of the Ti-Mo system at potentials of repassivation, there occurs an increase in the surface layer of titanium and a decrease in molybdenum.
