摘要
以金和锡作为贵金属镀层和非贵金属镀层的代表，进行不涂和涂覆润滑剂的微动实验，除测量接触电阻外，还在扫描电子显微镜和Ｘ射线能谱仪下对接触区域进行了观察和分析．发现微动条件下镀金层磨损明显；镀锡表面接触电阻在某一时刻迅速升高．涂覆润滑剂后，镀金层磨损减轻，镀锡表面接触电阻始终低于失效限．微动实验台的振荡频率为０．００３Ｈｚ，微动幅度为３０μｍ．
Effect of fretting on goldplated and tinplated contacts has been studied.In addition to contact resistance measurement, scanning electron microscopy (SEM) and Xray energy spectroscopy (XES) were used to study the contact zone.The fretting tests were carried out with a simulated contact apparatus at a frequency of oscillation of 0.003 Hz, microdisplacement of 30 μm.The results show that appropriate water soluble lubricant could reduce the wear of gold plating during certain number of fretting cycles and lubricant 9300 could effectively improve contact resistance behavior on tinplated surface during fretting.
