[0002] Laser cladding technology is a new surface modification technology that emerged in the 1970s with the development of high-power lasers. It refers to the rapid heating and melting of alloy powder or ceramic powder and the substrate surface under the action of a laser beam, and the self-excited cooling after the beam is removed to form a surface coating with a very low dilution rate and metallurgical bonding with the substrate material, thereby significantly improving the wear resistance, corrosion resistance, heat resistance, oxidation resistance and electrical properties of the substrate surface. Laser cladding technology can greatly improve the hardness, wear resistance and corrosion resistance of the surface of parts.
