摘要

采用粉末冶金工艺制备了w（Sn）/w（Cu+Sn）比值分别为0、6%、9%和12%的Cu基耐磨材料

对其组织结构、显微硬度变化幅度和不同载荷下的摩擦磨损性能进行分析。结果表明

Cu基耐磨材料中加入Sn可明显提高其显微硬度和耐磨性;w（Sn）/w（Cu+Sn）为9%时

主要磨损机制为磨粒磨损

并且在高载荷下呈现出了较好的耐磨性。

Abstract

In order to understand the effects of copper-tin ratio on the friction and wear properties of copper-based friction materials

the copper-based friction materials with w（Sn）/w（Cu+Sn）of 0

9% and 12%（in weight）were prepared by powder metallurgy process.The microstructure and micro-hardness as well as friction and wear properties under different applied loads were analyzed.The results show that the micro-hardness of copper matrix and the wear resistance of the materials are improved obviously by adding metallic tin in copper-based friction materials.When w（Sn）/w（Cu+Sn）is 9%

the main wear mechanism is abrasive wear

demonstrating better wear resistance at high applied load.
