Zusammenfassung:In this paper effect of a fiber laser on the microstructure and properties of steels 95X18 and 12X18H10T is shown. The regularities of changes in the structure of a laser-treated surface by X-ray diffraction and X-ray microscopic analyzes were studied. The high efficiency of laser heat treatment of steel 95X18 with the subsequent tempering, to improve the tribological properties of the surface layers has been established. For steel 12X18H10T laser shock hardening method (405 HV) is recognized to be effective.
