Abstract

In paper the research results of effect the operating parameters of new composite bearing materials based on nickel alloyed by molybdenum and tungsten with solid lubricant — calcium fluoride CaF2 for formation of dissipative secondary structures (friction films) have been presented. It was shown friction parameters have an essential influence for secondary structure’s nature in charge of antifriction properties level. Wear mechanism of materials has been researched in different conditions of friction. It was shown antiscoring friction films with smoothing microgeometry of surface contact relief are formed at speeds of rotarion 800−1000 turns/min., loads 6 МPа on air. It was determined formed friction films ensure high wear-resistance of bearing materials based on nickel at such friction conditions for rotation offset printing machines.
