中文摘要：
分析了纯铜及合金Cu-Cr、Cu-Zr、Cu-Cr-Zr的力学性能、导电性能和耐蚀性能,研究了微量元素Cr、Zr的添加对纯铜性能的影响.结果表明,微量元素Cr、Zr的添加可显著提高纯铜的强度,强化方式为析出强化;时效过程中析出的弥散相从一定程度上阻碍了电子的运动,使合金的导电性能降低;在中性盐雾环境中,纯铜及合金的失重速度随时间延长呈上升趋势,微量Cr的添加可以提高纯铜的耐蚀性能,而微量Zr的添加则使纯铜的耐蚀性有降低的趋势.
英文摘要：
Effect of microelement Cr and Zr on performance of copper alloy was studied through mechanial performance, electric conductivity performance and corrosion performance tests of pure copper and Cu-Cr.Cu-Zr.Cu-Cr-Zr alloy. It shows that Cr and Zr alloying element can improve the strength notably, strengthing method is precipitation strength, the electric conductivity of copper alloy falls as dispersion phase yielded in aging treatment blocks the movement of electron, weight-loss rate of pure copper and alloy increases with exposure time in NaCl fog environment, the corrosion resistance of alloy increases with addition of Cr and contrarily decreases with addition of Zr.
