摘要：
The working mechanism of ferrochrome in a new type of copper-based P/ M friction material was studied. The results show that ferrochrome can significantly improve the hardness of the matrix, high temperature resistance, corrosion resistance and other performance of the copper-based friction material, especially the mechanical performance, the friction and wear properties. The affinity of Cr and O is greater than Fe and O. CrO or Cr2O3 is formed by Cr which can work as the reduction in the sintering process, that's why the friction coefficient and wear resistance are improved.
