Numerous investigations testify that technological methods of friction part surface modification are effective means of fight against wear. Wild dissemination of technological lasers for given property surface layer formation is kept back because of potential possibilities of different materials laser treatment are completely not unveiled yet. The conditions of laser radiation interaction with structural steel used for making of high-loaded rolling-contact bearings worked under conditions where cyclic contact loads are in action have been investigated by us. The regularity of physical mechanical properties and microstructure variations in laser affected zone have been revealed and the main characteristics effected on resistibility of surface layers to flaking and wear have been determined. The optimum characteristics of laser treatment process have been established. The influence of laser track disposition on operating surface on service properties has been studied. The recommendations for application of investigation results for increasing in carrying capacity of high-loaded rolling-contact bearing have been elaborated.
