摘要
在KI体系中采用电刷镀方法在铜基体上制备了银/银-石墨烯复合镀层,研究了镀液中石墨稀含量对所制备复合镀层附着力、接触电阻、物相、耐蚀性和耐磨性的影响.结果表明:纯银镀层和复合镀层的附着力都达到标准要求;在NaCl和H2SO4腐蚀介质中,复合镀层的腐蚀速率均小于纯银镀层,在NaOH腐蚀介质中则相反;复合镀层的平均摩擦因数和磨损率最低,分别为0.274和5.68×10-6 mg/(m·N),远小于纯银镀层,接触电阻与纯银镀层相差不大.
Abstract
The silver/silver-graphene composite coatings were prepared on copper substrate in KI system by electric brush plating technology.The effects of graphite content in electrolytes on adhesion,contact resistance,material phase,corrosion resistance and wear resistance of the composite coatings were investigated.The results show that the adhesion of both pure silver coating and composite coating met the standard requirements.The corrosion rates of the composite coatings were less than that of pure silver coating in NaCl and H2SO4 corrosive media,which was inverse in NaOH corrosion medium.The lowest average friction factor and wear rate of composite coatings were 0.274 and 5.68×10-6 mg/(m·N),respectively,which was much smaller than that of pure silver coating,and the contact resistance of composite coating was not much different from that of pure silver coating.
