Specific features of the wear of an iron—graphite material with molybdenum disulfide additive produced by compaction followed by sintering or infiltration with tin bronze are studied. It has been found that in the course of friction the lubricant and hard wear particles accumulate in pores on the surface of the sintered material, which leads to the abrasive wear of the counterbody. During the friction of the infiltrated materials, selective mass transfer occurs due to the morphology of the copper phase, and the wear surfaces of these materials have a sponge—capillary structure. The wear resistance of the infiltrated materials is 2.5–3.3 times higher than that of the sintered materials. © 2015, Allerton Press, Inc.
