Abstract
The invention discloses a metal nickel ceramic coating good in high-temperature-cracking-resistant peeling capacity. Metal nickel is selected as a metal base. The surface of base metal is coated with a coating manufactured with barium oxide, alumina and other refractory materials as the ceramic phase. Alloy elements in the base metal will be diffused to an interface and have a reaction that NiO and M react to produce MO and Ni and other interface reactions with NiO and other matter in the coating, precipitated active nickel atoms and the base metal M are reduced to form Ni-M metallic bonds, and therefore the adherence between the metal ceramic coating and the base metal is improved; rare earth nano cerium dioxide is high in activity, and therefore the interaction between atom orbits of adsorbed molecules can be enhanced, and the reactions are promoted; and added iron powder and added nickel powder are combined so that the permeability of the coating can be enhanced. According to the metal nickel ceramic coating, an effective solution is provided for improving the high-temperature-cracking-resistant peeling capacity of metal ceramic coatings. A method is easy to operate and high in efficiency, and the service life of the coating can be longer.
