The effects of micro-hardness of Cu based friction materials to wear rates and the wear rates ratio of the pair and the friction materials

摘要

The four kinds of Cu based friction materials with different micro-hardness were fabricated by sintering method, the Ti content of four kinds of Cu based friction material is 8%, 12%, 16% and 20%, respectively. The tribological properties were carried out on ring-to-block tester. The results show that the wear rates and the wear rates ratio of the pair and the friction material with lower micro-hardness were lower than that of friction material with higher micro-hardness, and lower wear rates ratio of pair and friction materials (WRRPF) is very helpful for protecting pair of friction materials.
