摘要

研究了Co元素对Cu-Ni-Si合金的电导率、硬度和耐腐蚀性能的影响。结果表明

添加0.1%的Co可以提高合金的电导率

过量添加Co则导致电导率下降。试样的硬度及其在3.5%的NaCl水溶液中的耐腐蚀性能均随着Co添加量的增大而逐渐增强。通过调整Co添加量和时效时间

试样的硬度（HV）可调范围为200～266

电导率的可调范围为17.40～26.10 MS/m。

Abstract

The effects of Co addition on the electrical conductivity

hardness and corrosion resistance of Cu-Ni-Si alloy were investigated. The results show that the electrical conductivity of alloy is increased by adding 0.1%Co

and the excessive addition of Co leads to the decrease of electrical conductivity. The hardness and corrosion resistance in 3.5%NaCl aqueous solution of specimens are gradually enhanced with the increase of Co addition. By adjusting the amount of Co addition and the aging time

the adjustable range of hardness is 200～266 HV and that of electrical conductivity is 17.40～26.10 MS/m.
