CHARGE FOR INDUCTION SURFACING OF WEAR-RESISTANT ALLOY Russian patent published in 2021 - IPC B23K35/36 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to the field of hardening of parts by induction surfacing with wear-resistant materials. As a metal alloy, the charge contains a wear-resistant alloy of the Fe-Si-C-Cr-Cu-Mn-Ni system, obtained from acid-resistant cast iron ferrosilite grade FS-17 and high-chromium, wear-resistant cast iron grade Sormayt No. 1 and copper grade M1 with the following component ratio, wt. %: ferrosilite FS-17 55-65, Sormayt No. 1 25-20, copper M1 20-15, flux based on boron-containing components being the rest. As a flux based on boron-containing components, it contains a mixture of fused flux for induction surfacing of grade P-0.66 and boron carbide, with the following component ratio, wt. %: flux P-0.66 80-85, boron carbide 20-15.

EFFECT: increase in the wear resistance of the deposited metal under conditions of abrasive wear with alternating shock loads, a decrease in the content of scarce alloying elements (Cr, Mn) in the material, a decrease in labor intensity and an increase in manufacturability when applying a strengthening coating by induction surfacing.
