银基电接触材料的研究现状及发展趋势

摘要

从电接触材料的电学、力学和加工性能等要求出发,介绍了银基电接触材料的种类、特点、性能及研究进展.分析比较了常用银基合金(Ag-Ni系、Ag-W系和Ag-RE系)和银基氧化物(Ag-ZnO、Ag-CuO和Ag-SnO2)电接触材料的制备方法及优缺点.发展无公害环保型并能广泛适用的新型节银电接触材料,已成为目前银基电接触材料研究、应用的重点.%According to the requirements on electrical, mechanical and processing performance of the electrical contact materials, the type, features, performance and research progress of silver-based electrical contact materials were reviewed. The advantages and disadvantages and preparation of the commonly used silver-based alloys (Ag-Ni, Ag-W and Ag-RE department) and silver-based oxide (Ag-ZnO, Ag-CuO and Ag-SnO2) electrical contact materials were analyzed and compared. Developing pollution-free, environment-friendly and widely applicable new section of silver-based electrical contact materials has become the research and application focus of the silver-based electrical contact materials.
