Abstract

The invention discloses a method for preparing a corrosion and abrasion resisting coating through supersonic electric arc spraying. The method comprises the following steps that a matrix is subjected to surface roughening, and impurities on the surface of the matrix are removed; a surface roughness tester is used for carrying out quality inspection on a sprayed part of the matrix; an abrasion-proof material such as monel alloy or cobalt-gold alloy or nickel-tungsten alloy or a composite hard material is selected; supersonic electric arc spraying is carried out on the sprayed part of the matrix to prepare the metal coating, wherein the spraying speed ranges from 300 m/s to 400 m/s; and low surface energy matter is sprayed on the coating, drying is carried out at the temperature ranging from 800 DEG C to 1,200 DEG C, and the corrosion and abrasion resisting coating is prepared, wherein the hardness of the coating is HV397, the coating is of a layer texture structure, the void ratio of the coating ranges from 0.9% to 2.3%, and the average particle size of spraying particles is 4.32 micrometers. The obtained coating is better in bonding strength, lower in void ratio, more uniform in compactness, free of deformation of the sprayed matrix and very high in corrosion and abrasion resistance.
