Abstract
An experimental study of the tribological characteristics and microgeometry surface parameters subjected to various types of machining for two antifriction copper- and aluminum-based alloys in the running-in period was carried out. The material, load, and initial surface microgeometry effects were analyzed. It is shown that at low loads microgeometry has a stronger effect on tribological characteristics than at high loads. For the minimum and average normal load values, the effect of formation of equilibrium roughness, independent of the initial friction surface quality, was revealed. For polished surfaces with low roughness, the formation of a developed anisotropic relief corresponding to the adhesive wear mechanism has been established.
