Embodiment Construction

[0012] The described metal nickel ceramic coating for the surface of medium and low carbon steel is characterized in that it is made of the following raw materials in parts by weight: nano cerium dioxide 16, nickel powder 39, titanium diboride 14, iron powder 17. Ferric oxide 23, ferroboron alloy powder 13, butyl oleate 11, alum ore tailings 23, calcium carbonate 8, light diesel oil 6, appropriate amount of water.

[0013] The preparation method comprises the following steps:

[0014] (1) Treat nano-cerium dioxide at 650-760°C for 30-50 minutes at high temperature, quickly cool to room temperature with liquid nitrogen, add calcium carbonate and ultrasonically shake for 20-40 minutes, add butyl oleate and stir, and stir at room temperature 5-8h, dry to constant weight;

[0015] (2) Add ferric oxide into the ball mill, spray mist light diesel oil and mix well, add alum ore tailings, ball mill, mix and disperse at 340-450°C to obtain modified ferric oxide ;

[0016] (3) Calcin...

Abstract

The invention discloses a metallic nickel-based ceramic coating for low-carbon and medium-carbon steel surfaces. According to the metallic nickel-based ceramic coating, metallic nickel is used as a metallic base, a ceramic coating prepared by using the refractory substances of titanium diboride, ferric oxide and the like as ceramic phases is coated on the surface of the base metal, alloy elements in the base metal diffuse towards an interface and carry out the interface reactions specified in the description with the substances of NiO and the like in the coating, and the reduced-precipitated activated nickel atoms form Ni-M metallic bonds with the base metal M, thus improving the adherence between the metallic ceramic coating and the base metal; rare-earth nanometre cerium oxide is capable of enhancing the atomic orbital interaction effect thereof among adsorbed molecules due to high activity, thus improving the wear resistance of the product; and combination of the added ferrous powder and nickel powder is capable of enhancing the permeability of the coating. The metallic ceramic coating prepared by the method disclosed by the invention has rust and corrosion resistance and oxidation resistance, and wide applications in low-carbon and medium-carbon steel surfaces.

Description

technical field [0001] The invention relates to the technical field of metal ceramic coating materials, in particular to a metal nickel ceramic coating used on the surface of medium and low carbon steel 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 wor...
