激光熔覆技术是一种用各种熔覆材料的方式在工件的表面上放置所需的熔覆层材

Laser cladding technology is a method that uses various cladding materials to place the required cladding layer material on the surface of the workpiece. Under high-energy laser irradiation, the coating and the thin layer on the surface of the workpiece are melted and combined. After rapid solidification, a high-wetting and low-dilution cladding surface coating is formed, which significantly improves the new processing technology of the workpiece surface with excellent properties such as wear resistance, corrosion resistance, and oxidation resistance. Today, laser cladding has gradually advanced to industrial production and other fields after many years of development, and has a certain position in aviation, automobiles, petroleum, coal mines, electric power, and biomedical industries.

激光熔覆技术是一种用各种熔覆材料的方式在工件的表面上放置所需的熔覆层材料，在激光高能量的照射下使涂层和工件表面薄层两两熔化而结合，而后经快冷凝固后形成润湿度高、稀释度低的优良性能熔覆表面涂层，从而显著的改善了工件表面的抗磨损、抗腐蚀性、抗氧化性等优良性质的新型加工技术。现如今激光熔覆历经多年发展逐渐向工业生产等范围推进，在航空、汽车、石油、煤矿、电力、生物医用工业等方面占有着一定的地位。
