摘要：

Some properties of the Fe-based P/M composites sintered and reinforced by infiltration with Cu-Sn alloy were described. It is shown that the hardness of the sintered material is 2.5 times lower, tensile strength is 1.7 times lower and the wear resistance is 2.5-3.3 times lower in comparison with those of the infiltrated material. The presence of pores on the friction surface of the sintered material affects the features of the wear process. Due to the specific morphology of copper in the infiltrated material, the phenomenon of selective mass transfer is observed and worn surfaces have a spongy-capillary texture.
