Experimental studies of laser modification of the surface of 12Cr18Ni10T stainless steel in a layer of graphite paste and nanodispersed titanium dioxide powder (anatase) were carried out. It was established that as a result of laser pulsed processing, a microheterogeneous modifying layer is formed on the surface of the samples. The surface is characterized by increased microhardness and microroughness parameters, which depend to a greater extent on the pulse voltage. In the diffusion layer of the experimental samples, the formation of fine particles with sizes ranging from 100 to 300 nm was revealed
