摘要
触点材料微动特性是电连接器类机电元件的重要特性之一。微动失效机理复杂多样,影响因素众多,近年来一直是电接触领域的研究热点。本文总结了近年来国内外关于微动磨损特性的测试分析方法,主要涉及微动机构的设计、接触电阻的测量及材料分析测试等,可为微动磨损失效机理的确定、触点基体材料和镀层材料的优选及制备工艺的优化提供借鉴和参考。
The fretting wear of contact materials is one of the most important characteristics of the electromechanical components like electrical connectors. The failure mechanism, influenced by many factors, is very complicated, making it the research focus in electrical contact fields recently. This paper summarizes the testing analysis methods of the fretting wear characteristics in recent years, involving the design of fretting wear devices, the measurement of contact resistance and the testing analysis methods for contact materials. Thus it can provide references for the determination of fretting wear failure mechanism, the best combination of substrate materials and coating materials and the optimization of manufacturing processes.
