Estimation of the Corrosion Resistance of the Metal Coatings Formed by Powder Metallurgy

详细

A method is suggested to restore the worn surfaces of the components of food-processing equipment, which operate in an aggressive medium and are subjected to corrosive mechanical wear, by electrocontact welding of metallic powders placed in metallic-network containers. A combined additive, which allows one to exclude the losses of adding powder, is used. The corrosion penetration depth in an aggressive medium for metal coatings with a cast-iron addition is studied experimentally.
