Laser cladding technology uses high-energy laser beam irradiation to clad a layer of material with special physical, chemical or mechanical properties on the surface of the substrate through rapid melting, expansion and solidification, thereby forming a new material different from the substrate.

In the marine environment, improving the corrosion resistance of metal materials is an effective protective measure. Among many surface treatment technologies, laser surface cladding technology has a good effect in improving the corrosion resistance of metal surfaces.

However, the use of laser cladding machine to repair worn parts does not require preheating of the workpiece, and the size of the journal can be restored, and the subsequent processing volume is small, and no metallurgical cracks are generated.

Laser cladding equipment uses a high-energy laser beam as a heat source to cladding powder materials on the surface of parts to prepare high-performance protective coatings, thereby improving the surface hardness, wear resistance, corrosion resistance, oxidation resistance, high temperature resistance and other properties of the material. Compared with other metal repair processes, the metal additive manufacturing processes has significant advantages.

The metal additive manufacturing processes has been widely used in the metallurgical industry, coal industry, petrochemical industry, power machinery industry, machinery manufacturing, textile industry, hardware tools and other industries.
