It was established that the corrosion resistance of the coatings in neutral and weakly acidic media inversely-proportional to their chemical microhetrogeneity (KMG). The chemical composition of cored wires in the shell of steel 08 kp for generating of wear resistant coatings with enhanced corrosion resistance in neutral aqueous solutions have been justified. It has been found, that adding to charge composition components (ferrophosphorus, ferrosilicon or self-fluxing PG-10H-01) which are capable to form a low melting eutectic, provides a complete fusion between the powder charge and its shell in the combustion zone of the electric arc, thereby improving the chemical homogeneity of the coating. The formulas for calculating the amount of chromium in the composition of the cored wires, which is necessary to ensure its content in the lamellae of coatings not less than 12 wt. % have been proposed.
