Abstract: Ceramics materials have the characteristics of high hardness, high melting point, and high corrosion resistance. They are often used in the surface strengthening modification and remanufacturing repair of key parts of mechanical equipment. With the increasingly harsh service conditions of equipment, the moving parts of equipment made of traditional metal materials are prone to wear, corrosion, deformation, and other failures in the service process, which will lead to the degradation of service performance and even lead to malignant faults of equipment. As an efficient surface strengthening and remanufacturing technology, laser cladding has important application prospects in improving the wear resistance, corrosion resistance, heat resistance, and high-temperature oxidation resistance of substrate surface. The preparation of ceramic coating on the surface of parts by laser cladding technology is of great significance for prolonging the service life of key parts, improving resource utilization, and saving rare and precious metal materials. Firstly, laser cladding ceramic coatings are classified and introduced according to the microstructure and forming mechanism of ceramic coatings; Then, combined with the typical defects of the ceramic coating prepared by laser cladding, the common methods of coating quality optimization are described in detail; Then the application of laser cladding ceramic coating in improving the corrosion resistance, wear resistance, high-temperature resistance and biocompatibility of parts are reviewed; Finally, the development status of laser cladding ceramic coating technology is summarized, and the development trend of laser cladding ceramic coating technology prospects.
