电触点材料广泛应用于电气开关、继电器、接触器以及断路器等各种低压开关器件中,其特性对整体电气系统的开关容量、可靠性、稳定性以及使用寿命具有极其重要意义.传统 Ag 基触点材料具有良好的抗熔焊及耐电弧烧蚀性能,但仍然存在接触电阻大、界面结合强度低、塑性差等缺陷,其应用也在一定程度上受到限制.近年来,国内外研究工作人员在传统 Ag 基触点材料的研究基础上报道了 Ag-SnO2-MeO、Ag-GNPs、Ag-MAX 及Ag-RE等新型组元触点材料的研究工作.将从新型 Ag 基触点材料的发展背景出发,综述其组织与性能以及电弧侵蚀性能等方面的研究现状,最后总结新型Ag基触点材料面临的关键科学问题和挑战,并展望其未来的发展动向.
Research progress of new component contact materials and their arc erosion
The electrical contact materials are widely used in various low-voltage switching devices such as elec-trical 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.In recent years,domestic and foreign researchers have reported new group element contact materials such as Ag-SnO2-MeO,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 fa-cing new Ag-based contact materials and look forward to their future development trends.
