The article presents the results of volumetric modification with synthesized nanoscale titanium carbide of the ceramic coatings obtained on eutectic silumin in the process of micro-arc oxidation. A significant effect of TiC, injected at various concentrations into the electrolyte to the structure and tribomechanical properties of the coatings has been found. This is primarily expressed in the increased (at least 3 times) content of corundum in the coating, which leads to an increase in wear resistance of 2-fold while the coefficient of friction decreased by 1,3 times.
