THE WORDING OF FERROCHROME IN COPPER- BASED P/M FRICTION MATERIAL

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.
