Introduction High temperature oxidation resistanceof alloys depends on the formation of adense oxide scale with slow growing rateon its top surface. The α-Al;O;films appearto be the oxide with the lowest growingrate. In the CoCrAl systems, the continuousα-Al;O;can not be formed if the contentof aluminium in the alloy is less than severalhundredths. For the improvement ofoxidation resistance of MCrAl （M=Co,Ni and Fe）, many studies have been conducted展开更多
