In the paper the friction film formation analysis of the new composite bearings based on powder nickel alloy EP975 with solid lubricant CaF2 powder after tribological tests has been presented. Dense films are formed during friction of contact surfaces for tribological tests at high speed (or temperature) and loads. Such films consist of chemical elements of friction pair and air oxygen. Friction film is a determining factor for the antifriction material. It is connected with the nature of friction films. The films can minimize friction and ensure stability of a friction unit. It depends on the combination of chemical elements and oxygen in the films formed. The chemical composition of friction films not only allows ex-plaining the mechanism of their formation, but also gives the possibility to forecast and control the functional properties of bearing materials in wide range of printing machines under operating conditions. New composite bearings can be successfully used in the military equipment nodes, such as sliding divices nodes of artillery weapons.
