Improvement of Oxidation Resistance of A NiAl Eutectic Alloy Doping with Dy

Abstract:

Article Preview

The isothermal oxidation behavior of NiAl-30.9Cr-3Mo-0.1Dy alloy has been investigated in the paper. The results reveal that Dy-addition significantly improves the oxidation resistance, which is attributed to the formation of continuously compact Al2O3 layer and rich-Cr transition layer on the surface of the tested alloy.
