Modification of the materials surface layer for plain bearings

The results of investigating the possibilities of improving tribological properties of materials for bearings using a new combination of technological methods - plastic deformation of the surface layer and its subsequent break-in on a specific technology. The essence of the modification is to manage the creation of a positive stress gradient strength in depth, pre-hardened surface layer, using phenomena return, achieved earnings. There are conditions of the experiments on samples of two bearing alloys used in modern piston engines. Provides detailed evaluation of the results - in the carrying capacity of the modified surface, the length of the running, characteristics wear and temperature conditions coupled with the running process. Emphasizing the possibility of a significant increase in service properties of the study group on the basis of materials submitted by the method of inoculation.
