研究了添加铝粉或锡粉以及用６－６－３青铜粉全部或部分代替铜粉所制得的粉末冶金铜基摩擦材料，分析了基体成份对材料硬度、摩擦因数和磨损量的影响．研究结果表明：与纯铜基材料相比，铝含量为３．５％（质量分数）或含少量６－６－３青铜粉的摩擦材料，在低转整、小比压时，摩擦因数不降低，而磨损量减小，硬度得到提高；含锡摩擦材料的摩擦因数和磨损量都急剧降低，但硬度增加．
The effects of matrix composition on the hardness, friction coefficient and wear amount of the powder metallurgy copper-based friction material prepared by adding aluminum powder or tin powder and replacing all or part of copper powder with 6-6-3 bronze powder were studied. The results show that compared with the pure copper base material, the friction material with 3.5% aluminum content or a small amount of 6-6-3 bronze powder has lower friction coefficient Decreased, and the amount of wear decreased, and the hardness increased. The friction coefficient and wear amount of tin-containing friction material decreased sharply, but the hardness increased.
