摘要
研究了在石墨、SiO2等非金属颗粒表面化学镀铜的工艺和配方，然后将镀Cu的非金属颗粒 加入到Cu-Fe基金属粉末中，混料、压制、烧结成试验用摩擦材料。进行了摩擦材料的抗压 、抗弯强度试验，结果表明，镀Cu的石墨比未镀Cu的石墨，能明显提高摩擦材料的强度。探 讨了镀Cu的非金属颗粒能改善摩擦材料强度的机理。
The electroless Cu plating of non-metallic particles was adopted for surface metallizing of graphite and SiO\-2 particles ,so ad to improve the bonding state of non-metallic particles with alloy particles.The surface metallized non-metallic particles were sintered with Cu-Fe alloy powder.It showed that the strength of sintered friction materials could be obvilusly improved.
