Deforming cutting is a modern method of surface plastic deformation of a material. To date, a lot of studies have been carried out on the heat treatment of parts after deforming cutting, however, the combination of this method of material surface treatment with subsequent chemical-thermal treatment has been studied to a much lesser extent. The paper presents the results of studies of steel 20H after deforming cutting and subsequent chemical-thermal and heat treatment. The results of studies are presented of ribbed surfaces structure after vacuum carburizing, vacuum nitriding and liquid boriding. The depth of saturating elements penetration into intercostal gaps during chemical-thermal treatment by various methods has been investigated.
