研究了铜含量对铁基减摩材料组织性能的影响。一方面铜是铁基材料的强化元素，能提高材料的力学性能；另一方面铁基烧结合金基体中的不少孔隙是由铜粉扩散后留下的，因而铜又间接削弱合金力学性能。研究认为含铜量为５％左右时，合金的力学性能最高，而且基体中有足够的孔隙起自润滑作用，即合金作为减摩材料综合性能最高。添加磷组元后，铜对合金力学性能特别是拉伸强度的负作用被消弱
The effect of copper content on the microstructure and properties of iron-based anti-friction materials was studied. On the one hand, copper is the strengthening element of iron-based material, which can improve the mechanical properties of the material. On the other hand, many pores in the iron-based sintered alloy matrix are left by the diffusion of copper powder, so copper indirectly weakens the mechanical properties of the alloy. The results show that when the copper content is about 5%, the mechanical properties of the alloy are the highest, and there are enough pores in the matrix to self-lubricate, that is, the alloy has the highest comprehensive performance as an antifriction material. Addition of phosphorus components, the negative effect of copper on the mechanical properties of alloys, especially the tensile strength is weakened
