摘　　要：采用粉末冶金工艺制备出AgNi触点材料。系统研究了镍含量、初始镍颗粒尺寸、添加物对AgNi触点材料物理力学性能及电性能的影响。研究结果表明:镍含量的增加有利于提升材料的力学性能,但团聚镍颗粒尺寸增大,增加材料的燃弧时间、燃弧能量及熔焊力;镍颗粒细化可提升材料的力学性能,缩短材料的燃弧时间、降低燃弧能量并较少熔焊力;微量高熔点添加物对力学性能影响甚微,但可改善纵向镍颗粒分布,增加材料的燃弧时间、燃弧能量并减少熔焊力。Using powder metallurgy technology to prepare AgNi contact materials.In this paper,we have systematically studied the effects of nickel content,initial nickel particle size,and additives on the physical and mechanical properties and electrical properties of AgNi contact materials.The results show that the nickel content increase is beneficial to improving the mechanical properties of the material,but it increases the size of the agglomerated nickel particles,increasing the arc time,arc energy and welding force of the material;The refinement of nickel particles can improve the mechanical properties of the material,shorten the arc time,arc energy,and reduce the welding force of the material;Trace amount of high melting point additives have little effect on the mechanical properties,but can improve the longitudinal nickel particle distribution,increase the arc time and arc energy of the material,and reduce the welding force.
