The Wording of Ferrochrome in Copper-Based P/M Friction Material

Abstract:

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, thats why the friction coefficient and wear resistance are improved.
