Chromium in the high-temperature alloy matrix a very important role is the formation of Cr2O3-type oxide film, so that high-temperature alloy parts have good oxidation and corrosion resistance. At present we found 15 kinds of deformation of high temperature alloy oxidation weight gain and chromium content of the relationship between the view, although the alloy’s matrix is different, other alloying elements of the difference is also very large, but still can see, chromium on the oxidation resistance of the improvement of the role of obvious, and the higher the content of chromium, the better the antioxidant properties. The same chromium content continues to increase, the maximum corrosion depth of the alloy in the thermal corrosion environment continues to reduce, and the thermal corrosion resistance continues to improve.
