The article provides a tribological study of new strain-thermal method of achieving friction surfaces of materials for sliding bearings improved antifriction properties (high resistance to scoring, running-in, etc.). by creating a modified surface layer. The method is based on the use of surface plastic impact with subsequent implementation of thermal phenomena return by frictional heating of a thin surface layer. Considered a number of the most important indicators of friction providing performance tribosystems in extreme conditions. On the basis of the laws of mechanics of deformable bodies, foundations of materials science and the laws of friction and wear evaluated possible transformation of these indicators in the favorable direction by using the new method are given conditions of experiments on samples bearing alloys used in modern piston engines. The results of an experimental study tribodeformation phenomena for these alloys in the base case and conducted a pre-modification of the surface layer. Noted a fundamental possibility of a significant increase of service properties of the study group on the basis of the application materials submitted by a method modification.
