Wear mechanism of ceramics during friction against tool and carbon structural steels has the resembling mode and the similar trends in its change with sliding speed increasing are displayed. Wear data are characterized by nice reproducibility. Similar trends in the change of wear with speeds were not revealed. Wear data in this case are characterized by poor reproducibility. Methodological problems of creating and designing.
Criteria are advanced to rate the rejection limits for the considered types of damage.
Theoretical and experimental means of solving contact problems and evaluating the applicability of topocomposites are considered. Leading problems of studies are treated. The mechanism of brinelling working surfaces of rolling bearings. The fine crystalline structure in the contact zone is modified, it softens and a prefailure nucleus originates. In rolling the moving balls and products of mechanical cracking of the lubricating material produce a pit in the prefailure nucleus.
