新型组元触点材料及其电弧侵蚀研究进展.

The electrical contact materials are widely used in various low-volt age switching devices such as electrical switches, relays, contactors and circuit breakers, and their characteristics are of great importance to the switching capacity, reliability, stability and service life of the overall electrical system. The conventional Ag- based contact materials have good performance, but still suffer from defects such as high contact resistance, low interfacial bonding strength, and poor plasticity, and their applications are limited to some extent. Tn recent years, domestic and foreign researchers have reported new group element contact materials such as Ag-Sn()2- Me(), Ag-GNPs, Ag-MAX and Ag-RE on the basis of the traditional Ag-based contact materials. This paper will review the current research status of new Ag-based contact materials in terms of their organization and properties as well as arc erosion performance, and finally summarize the key scientific issues and challenges facing new Ag-based contact materials and look forward to their future development trends.
