摘　　要：以纯铜粉和铜铬锆合金粉为原料,通过热压烧结法制备了由铜铬锆超细晶和铜粗晶组成的异质结构铜合金,研究了其在干摩擦条件下的摩擦磨损行为。结果表明,与均质结构铜合金相比,异质结构铜合金具有更稳定的摩擦因数、更好的耐磨性和更高的导电性能。性能的提高源于其独特的异质结构。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.
