Wear, corrosion, and fracture are the main reasons for the failure of equipment components, widely present in metallurgy, construction, power, machinery, and other fields, among which wear problems have the most serious impact on components. Especially for transportation equipment, about 80% of the failure causes of parts are material wear. Therefore, the issue of wear and tear has received widespread attention in the field of materials science.

In order to keep up with the pace of manufacturing development, surface engineering technology has emerged. This technology can significantly improve material performance with low investment and has significant economic benefits. In recent years, the preparation of wear-resistant ceramic coatings on the substrate surface has become a hot research topic for scholars at home and abroad.

Ceramics have the characteristics of high melting point, high hardness, high strength, high chemical stability, high insulation ability, low thermal conductivity, and low coefficient of thermal expansion. When used as coatings, it can effectively improve the wear resistance, high heat resistance, corrosion resistance, and high-temperature oxidation resistance of the substrate material. Ceramics have properties that are difficult for metal materials to achieve, so they are widely used in the preparation of various ceramic coatings. Wear resistant ceramics combine the advantages of ceramics with the toughness of metal materials. Spraying on the surface of the material can make the material possess both the strong toughness and machinability of metals, as well as the wear resistance, high temperature resistance, corrosion resistance, and insulation properties of ceramics. This is of great significance for improving social and economic benefits and extending the service life of components.

In the power industry, wear-resistant ceramic coatings have great potential for application. Coating the fans of thermal power plants with wear-resistant ceramic coatings can greatly improve their service life. The use of piston rods coated with wear-resistant ceramic coatings in the opening and closing machines of large-scale hydraulic engineering can effectively overcome the oil leakage and jamming phenomena that occur with traditional piston rods used for a long time. In the electronics industry, high dielectric constant coatings such as barium titanate coatings are widely used in the field of capacitors. High performance packaging materials for integrated circuit substrates prepared using the high-temperature electrical insulation performance of alumina coatings are also widely used.
