1. The magnitude of the mean-square deviation in heights of irregularities σ′ is not a comprehensive characteristic of the starting roughness of the counterbody for evaluating the wear of polymeric composites. The characteristic of the steel counterbody surface in magnitude of the mean radius of curvature of the peaks of the irregularities is very important.

2. On the basis of a study of profilograms of the friction surfaces and results obtained in a study of the wear of composites containing fillers of various hardnesses and dispersities which have been presented in this and preceding articles [3], it has been shown that the presence of filler particles leads to a significant change in the profile of the surface of the steel counterbody (peaks of irregularities are smoothed out, and the mean radius of curvature of the peaks of irregularities increases considerably, by a factor of severalfold). The harder the filler and the coarser the filler particles of a given type, the faster an optimum roughness is created, which ensures the lowest wear of the composite.
