Manufacturing method of bronze-based sintered friction material

摘要

A sintered friction material for use in a braking system for automobiles, heavy equipment, and trains is disclosed, and in particular, a method for producing a sintered bronze sintered friction material having excellent friction characteristics and wear resistance under severe conditions of high load and high speed. The bronze sintered friction material according to this method comprises 50 to 80 wt% of copper powder, 5 to 15 wt% of tin powder of bronze base metal, 10 to 50 wt% of friction modifier and 2 to 10 wt% of solid lubricant Wherein the friction modifier is composed of 5-15 wt% of iron powder, 7-15 wt% of molybdenum powder, 2 ~ 10 wt% of wear resistant additive powder and 2 ~ 10 wt% of ceramic short fibers have.
