A kind of TiAl based alloy with high temperature self-lubricating property was prepared by vacuum hot pressing sintering technology, and its mechanical and physical properties were tested. The friction and wear experiments were carried out at different temperatures, and the high-temperature tribological properties of the new TiAl based alloy were studied. The results show that the new TiAl based self-lubricating material with TiC, TiB 2 and CaF 2 can effectively improve the mechanical and physical properties of the matrix, and make it have good mechanical and physical properties as well as good tribological properties above 500 °C.
