Abstract: Laser cladding technology is a new technology for surface coating, which has been widely used at home and abroad. Laser cladding alloy materials include self-fluxing alloy materials, composite materials, ceramic materials, and so on. Laser cladding technology has some advantages, such as convenient operation, fast cooling speed, easy automation realization, and so on. It is easy to form a coating with high precision and good comprehensive performances on the surface of substrate. This study mainly focuses on the laser cladding ceramic coatings. The research status and development trend of oxides, carbides and bioceramic coating are addressed, and some problems about the laser cladding ceramic coating are discussed.

Key words: laser cladding; ceramic coating; surface modification
