Abstract

The invention discloses a powder core wire material for wear-resistant electric arc spraying and a coating preparation method, belonging to the technical field of metal surface corrosion and protection. The powder core wire material is composed of a cladding layer and a powder core, the cladding layer is stainless steel, the filling rate of the powder core is 25-35%, and the mass percentage of the powder core composition of the wire material is as follows: Cr 2 C 3 Powder: 25%‑40%, WC powder: 7%‑15%, V powder: 4%‑15%, Mo powder: 5%‑15%, Nb powder: 2%‑10%, Al powder: 8%‑ 20%, the balance is Fe powder. Surface preparation is required to prepare the coating before spraying. The coating prepared by the wire material of the present invention has no obvious defects, can form a continuous and dense coating, has good wear resistance and corrosion resistance, high coating hardness, high bonding strength, good mechanical properties and corrosion resistance. grinding performance.

Description

technical field [0001] The invention belongs to the technical field of metal surface corrosion and protection, and in particular relates to a wear-resistant electric arc spraying powder core wire material and a coating preparation method. Background technique [0002] Wear is one of the main forms of failure of metal equipment and components. According to incomplete statistics, 1 / 3 to 1 / 2 of energy is consumed in friction and wear, resulting in a large amount of energy consumption and huge economic losses, and even some disasters sex accident. At present, there are two main types of wire materials for arc spraying: solid core and powder core. Adding different elements to prepare a coating with strong adaptability, which has broad application prospects in the field of arc spraying. Surface treatment technology is one of the effective methods to improve the wear resistance and corrosion resistance of materials, and arc spraying is one of the important surface technologies. I...
