摘要：
The results of investigation of the isothermal oxidation wear mechanism of Ti-46Al-7Nb-0.7Cr-0.1Si-0.2Ni intermetallic alloy with AlCrN coating are presented. Tests in 9 %O-2 + 0.2 %HCl + 0.08 %SO2 + N-2 atmosphere were performed at a temperature of 700 degrees C. The structure of the specimen and chemical composition of the oxidation products were analysed using scanning electron microscopy and energy dispersive X-ray analysis. In addition, mass changes were investigated.
