Abstract

The invention discloses a metal matrix wear-resisting and corrosion-resisting surface coating composite material. The metal matrix wear-resisting and corrosion-resisting surface coating composite material is composed of a metal matrix, a metal matrix surface transition layer, a middle strengthening layer and an outer-layer surface coating. The metal matrix is composed of two or more kinds of metal powder. The metal matrix surface transition layer is composed of copper fluoride, boron carbide and zinc powder. The middle strengthening layer is composed of titanium dioxide and aluminum oxide, and the outer-layer surface coating is made of enamel. The metal matrix wear-resisting and corrosion-resisting surface coating composite material has good functions of wear resistance, corrosion resistance, high temperature resistance and oxidization resistance, and the metal matrix can be effectively protected against atmosphere oxidation, acid-base corrosion and other external damage. A preparing method of the metal matrix wear-resisting and corrosion-resisting surface coating composite material is scientific and simple, the obtained product surface coating is good in density, high in toughness and clear and firm in interface, no bubble or impurity can be generated, and the obtained product surface coating can be widely applied to the field of metal surface coatings and is worthy of popularization.

Description

Technical field [0001] The invention relates to the technical field of coatings, in particular to a metal-based wear-resistant and corrosion-resistant surface coating composite material and a preparation method thereof. Background technique [0002] Coating is a solid continuous film obtained by one application of paint. It is a thin plastic layer coated on metal, fabric, plastic and other substrates for protection, insulation, decoration, etc. The coating can be gaseous, liquid or solid, and the type and state of the coating are usually determined according to the substrate to be sprayed. Modern industry requires workpieces to be able to work under severe conditions such as high temperature and corrosion. Therefore, the requirements for workpiece materials are getting higher and higher. At the same time, coating protection is implemented on key parts of the workpiece, which can effectively protect the workpiece and save Cost of production. At present, the existing coating mate...
