The change in the microstructure, hardness and thickness of diffusion coatings with varying content of boron carbide salts in the melt is studied. For samples made of U10 steel, the highest saturation capacity with the formation of a carbide layer is characteristic of a composition containing 2% BC, 5-6% alloying elements (Cr, V, Ti), 10% NaCl, the rest is borax NaBO. The addition of 3-5% aluminum oxide significantly increases the stability of the melt and contributes to the preservation of the saturating capacity. The technology of complex saturation of steel with alloying elements can be used to harden parts of stamping equipment and a wide range of tractor parts.
