【摘要】 对不同含量、不同粒径金刚石超细颗粒增强Ａｇ基复合镀层的电接触性能进行了研究。结果表明，复合镀层中金刚石粒径越小，含量越高，其强化效果越好，电磨损率越小，而对接触电阻影响不大。更多还原

【Abstract】 The electric contacting properties of Ag-based composite coatings reinforced by ultrafine diamond powders with different powder contents and dimensions have been studied systematically in this paper. The experimental results manifest that: with the powder dimension decreasing and the contents increasing, the reinforcing effect increases and the electric wear decreases, while there is almost no effect on electric contact resistance.更多还原
