Earlier researches have proven that sliding bearings cooperating with different surface layers of s have shown different wear. There is also a difference between cooperation characteristics, which can be measured with help of different electric potential (GRP) in sliding couple. Analyzing changes in characteristics of generated potential difference effective value u s-grp during operation allows to estimate time Tg since the beginning until to forming of oil wedge shows up and estimate time Ts — says about stabilization tribological processes infrictional contact (running-in process was finished). This work will present the investigations results of s surface layer structure influence on the size of wearing of cooperating bearing and the characteristics of this cooperation. It has been proven, that there is a definite impact of a phase structure; with a good probability it became clear that grain size and placement and size of different phases also provided some impact on cooperation of pivots and bearings. Considering pivots covered with clear metallic coating, there have been proven impact of the type of metallic coating, macrostructure (density of crack mesh) have also been proven to be very influential.
