Corrosion resistant Ti-Cr-Ni alloy containing a platinum group metal

摘要

A corrosion resistant Ti based alloy comprising: Cr: 0.005-2.0 wt %, and further comprising one or more of elements selected from: -Ni: 0.005-2.0 wt %, Pd: 0.005-2.0 wt %, -Ru: 0.005-2.0 wt %, Pt: 0.005-2.0 wt %, -Os: 0.005-2.0 wt %, Ir: 0.005-2.0 wt %, -Rh: 0.005-2.0 wt %, and - the balance of Ti and inevitable impurities. Cr may be replaced with one or more of 0.005-1.5 wt % of Cu and 0.005-1.5 wt % of Si, or 0.005-2.0 wt % of Al. The corrosion resistant Ti based alloy has excellent corrosion resistance also in a non-oxidative atmosphere and also has an excellent crevice corrosion resistance.
