“…For example, it is necessary to increase the given pulse energy for refractory materials, but the scanning fre-quency of the surface under treatment should be also reduced in this case [1][2][3]. It is known that surface alloying of steels and alloys with titanium, tantalum, tungsten, and vanadium carbides can significantly increase their wear resistance [4][5][6].…”

An experimental study of the laser modification of the surface of 12Kh18N10T stainless steel in a layer of graphite paste and nanodispersed titanium dioxide powder (anatase) has been performed. It is found that a microheterogeneous modifying layer is formed on the surface of the samples as a result of pulsed laser treatment. The surface is characterized by increased microhardness and microroughness parameters, which largely depend on the pulse voltage. The formation of fine particles with sizes ranging from 100 to 300 nm is observed in the diffusion layer of the specimens.

“…Так, например, для тугоплавких материалов следует увеличить заданную энергию импульса, но при этом нужно умень-шить частоту сканирования обрабатываемой поверхности [1][2][3]. Известно, что поверхностное легирование сталей и сплавов карбидами титана, тантала, вольфрама и ванадия может значительно повысить их износостойкость [4][5][6].…”

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
