The possibility of using the anodic electrolyte-plasma carburization technology in a non-toxic electrolyte to increase the microhardness and wear resistance of commercially pure titanium is considered. The morphostructure and roughness of the material surface after saturation were studied, the distribution of microhardness in the surface layer and the tribological behavior of the modified surface were studied. Wear resistance tests were carried out under dry friction conditions using tool alloy hardened steel as a counterbody. It has been established that electrolyte-plasma cementation in an aqueous electrolyte, containing ammonium chloride and glycerin, increases surface hardness by 3.5 times, up to 900 HV0.01, due to the formation of a diffusion layer. Tribological behavior is influenced by high-temperature oxidation of the surface, leading to the formation of an outer oxide layer, the formation of a modified layer and the titanium surface relief. The friction coefficient after treatment increases by 1.2 times, and mass wear decreases by 3.4 times compared to the untreated surface of titanium parts.
