摘要：

Electrical contacts are core components of switch devices used in power systems, aerospace, automotive electronics, household appliances and communication equipment. The arc erosion of electrical contact materials has always been one of the crucial problems in electrical reliability. Arc erosion is a complex process, with varied factors and extreme service environments. Much work has been done to investigate the essence of arc erosion, develop new electrical contact materials, and enhance the reliability and life of contacts. In the experimental aspect, the electrical contacts' arc motion, material loss and transfer, morphology evolution, and composition changes were investigated through various characterization methods. In the numerical simulation aspect, the multi-scale and multi-physics models were used to calculate the material parameters and simulate the process of material-arc interactions, molten pool dynamic, and electric contact failure. This article states the physical process of the arc erosion of electrical contact materials, and reviews its experiment and numerical simulation research. Existing problems are discussed. The future trend is to build a coupling erosion model with the multi-scale and multiphysical field. © 2022 Cailiao Daobaoshe/ Materials Review. All rights reserved.
