Embodiment Construction

[0012] The wear-resistant metal nickel ceramic coating for a pot is characterized in that it is made of the following raw materials in parts by weight: nano cerium dioxide 15, nickel powder 42, iron powder 14, boron oxide 18, antimony trioxide 14. PTFE wax powder 9, aluminum dihydrogen phosphate 10, hydrogenated silicone oil 8, steel fiber 6, pure benzene emulsion 15, kaolin 23, appropriate amount of water.

[0013] The preparation method comprises the following steps:

[0014] (1) Treat nano ceria at 620-740°C for 30-50 minutes at high temperature, quickly cool to room temperature with liquid nitrogen, add aluminum dihydrogen phosphate and ultrasonically shake for 20-40 minutes, add pure benzene emulsion and stir to mix, Stir for 5-8h, dry to constant weight;

[0015] (2) Add boron oxide into a ball mill, spray into mist hydrogenated silicone oil and mix well, add polytetrafluoroethylene wax powder, and perform ball milling, mixing, and dispersing at room temperature to obta...

Abstract

The invention discloses a wear-resistant metal nickel ceramic coating layer for a pot; a ceramic coating layer prepared by selecting metal nickel as a metal base and adopting boron oxide, antimony trioxide and other refractory substances as a ceramic phase is coated on a substrate metal surface; an alloy element in the substrate metal can be spread to an interface and generates NiO+M->MO+Ni and other interface reactions with NiO and other substances in the coating layer; reduced and precipitated active nickel atoms and the substrate metal M form Ni-M metallic bonds, and thus the adherence between the metal ceramic coating layer and the substrate metal is improved, rare earth nano cerium dioxide can strengthen interaction with atomic orbits among adsorbed molecules due to active high energy, and the wear resistance of the product is improved; an added iron powder and nickel powder are combined to enhance the permeability of the coating layer; the method is simple to operate and high in efficiency, and the ceramic coating layer is long in life and not easy to damage.

Description

technical field [0001] The invention relates to the technical field of cermet coating materials, in particular to a wear-resistant metallic nickel ceramic coating for pots 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-sp...
