【Abstract】 Nb-based alloys are important high temperature structural materials because of their high melting temperature, corrosion resistance, and high temperature strength. However, one of the key problems that retards their application is their poor high temperature oxidation resistance. This paper reviews the present status of research on high temperature oxidation resistanant coating of Nb-based alloys. Existing problems are analysed and possible solutions are suggested.更多还原
