A method for manufacturing a high abrasion resistant alloy liner plate

Abstract

The application provides a preparation method of a high wear-resistant alloy lining plate and relates to the technical field of wear-resistant alloys. Carbon steel and pig iron are mixed, heated and melted, high-carbon manganese iron, medium-carbon chromium iron and ferrosilicon are added, temperature is refined, aluminum powder is added, a mold is entered, temperature is lowered and the mold is removed, temperature is homogenized, quenching is performed, cooling is performed, and a mother plate is prepared. Double male imide, composite powder and sepiolite fiber are mixed, heated and stirred, and then coated on the mother plate. Negative pressure is applied first, then positive pressure is applied, temperature is raised, and cooling is performed to obtain a base layer. The mother plate is placed in a magnetron sputtering device, chromium nitride functional layer is sputtered on the base layer, and cooling is performed to obtain the high wear-resistant alloy lining plate. The composite powder is prepared by mixing chromium carbide powder and hydrogen peroxide solution, heating, filtering, mixing with an ethanol solution and gamma-aminopropyl triethoxysilane, heating, condensing and refluxing, washing and drying, and mixing with an amino-terminated polyether and N,N-dimethylformamide and heating. The application can improve the wear-resistant stability of the alloy lining plate.
