【 摘 要 】

Sliding of metal composites against copper counterbody under severe conditions (i.e. at the contact current density higher 50 A/cm2and at high roughness of counterbody) is carried out. It is shown that the composite of composition of Cu-30% of graphite shows low wear resistance in these conditions. Higher wear resistance is inherent in the composites containing lead and bearing steel. Impregnation of these composites by industrial oil hasn't led to noticeable increase in wear resistance.
