Abstract: A preparation method of an electrical contact material includes steps of: adopting chemical plating to cover nickel coating on aquadag or metallic oxide, then covering with silver coating, and forming Ag—Ni—C or Ag—Ni—MeO core-shell structure, which improves interface wettability of aquadag, metallic oxide and silver matrix, and removes the adverse effect on the electrical contact material mechanical property due to bad interface wettability in conventional powder metallurgy method. What is important is that the silver in intermediate composite particles is replaced by nickel coating, thus reduce the silver use level. The main function of silver coating is to improve inoxidizability of composite particles, sintering granulation property and the deformability during the manufacturing process of intermediate composite particles, thus improve the technological property.

Abstract translation: 电接触材料的制备方法包括以下步骤：采用化学镀以覆盖水溶液或金属氧化物上的镍涂层，然后用银涂层覆盖，形成Ag-Ni-C或Ag-Ni-MeO核 - 壳结构，其中 提高了aquadag，金属氧化物和银基体的界面润湿性，并且消除了由于常规粉末冶金方法中的界面润湿性差而导致的电接触材料机械性能的不利影响。 重要的是中间复合颗粒中的银被镍涂层所取代，从而降低了银的使用水平。 银涂层的主要功能是提高复合颗粒的不可氧化性，烧结造粒性能和中间复合颗粒制造过程中的变形能力，从而提高技术性能。

Abstract: An iron-based sintered alloy of the present invention is an iron-based sintered alloy, which is completed by sintering a powder compact made by press forming a raw material powder composed of Fe mainly, and is such that: when the entirety is taken as 100% by mass, carbon is 0.1-1.0% by mass; Mn is 0.01-1.5% by mass; the sum of the Mn and Si is 0.02-3.5% by mass; and the major balance is Fe. It was found out that, by means of an adequate amount of Mn and Si, iron-based sintered alloys are strengthened and additionally a good dimensional stability is demonstrated. As a result, it is possible to suppress or obsolete the employment of Cu or Ni, which has been believed to be essential virtually, the recyclability of iron-based sintered alloys can be enhanced, and further their cost reduction can be intended.
