In this work, the effect of laser pulsed radiation on the surface of 12Cr18Ni10T stainless steel with a layer of graphite coating previously applied to it was experimentally investigated. It was established that as a result of laser pulsed irradiation, a significant increase in the microhardness of the surface layer of the experimental samples occurs to H=9.56±0.1 GPa. The results of studying the elemental composition of the surface structure showed an increase in the concentration of diffused carbon in the surface layer of steel.
