Abstract: The paper has introduced a new type of P/M sealing materials used under high temperature with the matrix of Ni-Cr by adding appropriate anti-friction components. They reach an operating temperature of 950~1000℃ and have high oxidation and wear resistance and superior anti-friction.They are suitable for sealing under high temperature in various gasoline turbine,combustion gas turbine and Other aviation engines.
