Abstract

A layer of Mo(Si,Al)₂ was prepared on the sample surface of Mo substrate by powder coating method using Al-Si mixed powder and then diffusion reaction in argon atmosphere at 900°C. The results of oxidation resistance showed that the Mo samples coated with the Mo(Si,Al)₂ layer had an excellent oxidation resistance in air even at 1200°C. The reason of oxidation resistance is the formation of a dense alumina film on the sample surface. Therefore, the further oxidization of the sample can be prevented. In addition, The formation of Mo₅(Si,Al)₃ layer was also observed at the interface between the Mo substrate and the Mo(Si,Al)₂ layer.
