摘　　要：从电接触材料与环境作用所产生不同类型的腐蚀出发,概述了电接触材料发生腐蚀的主要类型,分析了其腐蚀机制和特征,主要介绍了环境因素对电接触材料大气腐蚀的影响,并展望了电接触材料腐蚀机制的研究趋势。This paper is a state of the art survey on the current understanding of the corrosion mechanism in connection degradation of contact materials.Oxidation,Sulfuration,Atmospheric corrosion and Fretting corrosion in the processe of contact are considered.The mechanism of each type and its influencing factors are analysed.It is shown that the corrosion mechanisms of contacts in the actual environment are not well known.A number of conclusions are made which may improve further work in order to obtain a better understanding of the corrosion mechanism and the controlling factors in the corrosion behavior of contact materials in the atmosphere.
