Abstract

Abstract: A heterogeneous microstructure copper alloy composed of Cu-Cr-Zr ultrafine grains and copper coarse grains was prepared by hot pressing sintering using pure copper powder and Cu-Cr-Zr alloy powder as raw materials, and its friction and wear behavior under dry friction conditions was studied. The results show that compared with homogeneous microstructure copper alloy, heterogeneous microstructure copper alloy has more stable friction factor, better wear resistance and higher electrical conductivity. The improvement in performance is due to its unique heterogeneous structure.

Key words: heterogeneous microstructure, Cu-Cr-Zr alloy, hot pressing sintering, friction factor, fatigue wear
