氧化物腐蚀对工业应用金属表面形貌的影响是导致电接触失效的常见原因，随着现代电子器件的小型化，这一问题变得更加严重。本研究以99.9%铜/弹簧针接触件为研究对象，通过微动磨损实验，研究了三种不同气氛（氧气、空气和氮气）下接触件接触电阻的影响。结果表明，在氮气环境中，高摩擦系数下，接触电阻值最小且稳定。富氧环境促进氧化亚铜的形成，从而增加电接触电阻。采用扫描电镜和电子探针分别对磨损区的形貌和元素分布进行了分析。通过X射线光电子能谱分析研究了接触之间的表面产物，以解释微动过程中三个测试样品的不同电接触特性。
The effects of oxide etch on the surface morphology of metals for industrial application is a common cause of electrical contacts failure, and it has becomes a more severe problem with the miniaturization of modern electronic devices. This study investigated the effects of electrical contact resistance on the contactor under three different atmospheres (oxygen, air, and nitrogen) based on 99.9% copper/pogo pins contacts through fretting experiments. The results showed the minimum and stable electrical contact resistance value when shrouded in the nitrogen environment and with high friction coefficient. The rich oxygen environment promotes the formation of cuprous oxide, thereby the electrical contact resistance increases. Scanning electron microscope microscopy and electron probe microanalysis were used to analyze the morphology and distribution of elements of the wear area, respectively. The surface product between contacts was investigated by x-ray photoelectron spectroscopy analysis to explain the different electrical contact properties of the three tested samples during fretting.
