摘要
用化学镀在ＷＣ，Ｃ（石墨）粉末表面包复了一层Ａｇ［１］．改善了不同粉末间的浸润性，增强了颗粒间结合强度，使Ａｇ－ＷＣ－Ｃ系出头材料中备相分布均匀，性能提高．
A chemical plating method was used to coat WC and C powder with Ag. The experimental results shown that this method could improve the infiltration between WC, C and Ag powders and make phases distributed evenly. The electrical contact materials, which were made by silver plate powders, have some advantages in electrical contact materials, which were made by mechanical mixing powders. Such as: the resistivity decrease to 80-82%, the bending strength increase by a factor of 1.8, the contact resistance is lower, the experimental results of contact test at 30A, 105 cycle is stable and the property of anti-fusion welding is better.
