Embodiment Construction

[0012] The corrosion-resistant metallic nickel ceramic coating is characterized in that it is made of the following raw materials in parts by weight: nano cerium dioxide 15, nickel powder 38, aluminum oxide 11, boron oxide 13, iron powder 10, thorium oxide 14. Potassium nitrate 8, stearic acid 7, brucite fiber 6, methyl ethoxy silicone oil 2, konjac mannan 11, appropriate amount of water.

[0013] The preparation method comprises the following steps:

[0014] (1) Treat nano-cerium dioxide at 600-700°C for 30-50 minutes at high temperature, quickly cool to room temperature, add potassium nitrate and ultrasonically shake for 20-40 minutes, add konjac mannan and appropriate amount of water to grind for 5-8 hours, and spray dry ;

[0015] (2) Add alumina to the ball mill, spray into mist methyl ethoxy silicone oil and mix well, add stearic acid, and perform ball milling, mixing and dispersing at room temperature to obtain modified alumina;

[0016] (3) Calcining the modified alu...

Abstract

The invention discloses a corrosion resistant metal nickel ceramic coating layer; a ceramic coating layer, prepared by selecting metal nickel as a metal base and adopting such refractory matters as aluminum oxide, boron oxide and thorium oxide as ceramic phases, coats the surface of base metal; alloy elements in the base metal are dispersed to an interface to generate such interface reactions as NiO reacts with M to generate MO and Ni, with substances of NiO in the coating layer; active nickel atoms for reducing precipitates and the base metal M form Ni-M metal bonds, so that the adherence between the metal ceramic coating layer and the base metal is improved; rare earth nanometer cerium dioxide enhances atom orbital interaction among absorption molecules due to high energy of activity to promote the reactions, so that the adherence can be quickly built, and the corrosion resistance of the coating layer is improved; added iron powder and nickel powder are combined to enhance the permeability of the coating layer; and the method is simple in operation, high in efficiency and excellent in interlayer combination.

Description

technical field [0001] The invention relates to the technical field of cermet coating materials, in particular to a corrosion-resistant nickel metal ceramic coating and a manufacturing method thereof. Background technique [0002] In recent years, ceramic coating materials are ceramic materials that have received widespread attention. Traditional ceramic materials are brittle, which is not conducive to the further processing of ceramic materials, and also leads to slightly insufficient performance of ceramic materials in many fields. Metal-ceramic coating is a composite coating that not only has the good strength and toughness of metal, but also has the advantages of high temperature resistance, wear resistance and corrosion resistance of ceramics. Therefore, metal-ceramic coatings have gained important applications in many fields such as aviation and aerospace, such as rocket engine components that are subjected to complex and harsh working conditions such as high-speed, hi...
