Abstract In this study, high temperature friction and wear property of W5Re and W25Re alloy which prepared by
powder metallurgy were tested By means of electron probe, LEICA three- dimensional optical microscope, SEM
and EDS，the composition, roughness and microstructure of wear surface were gained. The results show thal
W25Re alloy has excellent friction and wear resistance at high-temperature .
