The oxidation mechanisms and failure mechanisms of W-based alloys indicate that the oxidation process can be divided into two distinct phases. The rate of oxide film formation and the stability of the structure are the key factors affecting the oxidation resistance of W-Cr alloys. the Si and Cr elements are easily oxidized to form a stable protective film. Therefore, the oxidation properties of W-Si-based alloys and W-Cr-based alloys have been extensively investigated.

The mS values vs. time of W-Cr-Zr oxidation tests at 1000 temperature image

Researchers prepared W-Cr-Y-Zr alloy and investigated its oxidation behavior. Elisa et al. prepared W-10Cr-0.5Y and W-10Cr-0.5Y-0.5Zr (wt%) alloys by HIP and heat treatment (HT) techniques. The surface image results show the morphology of the heat-treated W-10Cr-0.5Y and W-10Cr-0.5Y-0.5Zr (wt%) alloys with heat treatment temperatures and times of 1550°C and 1.5 h.
