Ultra-high-speed laser cladding technology is mainly used to improve the wear resistance, corrosion resistance, high temperature resistance, and oxidation resistance of the surface of the parts, so as to achieve the goal of surface modification or repair, and meet the requirements for the specific performance of the material surface. In the conventional laser cladding process, the laser energy is mainly used to melt the base material to form a molten pool. The powder is poured into the molten pool and melted, and then solidified to form a protective coating.
The ultra-high-speed laser cladding technology essentially changes the melting position of the powder, so that the powder will be melted by the laser at the top of the workpiece, and then uniformly coated on the surface of the workpiece. Its cladding rate can be as high as 20-200m/min. Due to the low heat input, this technology can be used for surface cladding of heat-sensitive materials, thin-walled and small-sized components, and it can be used for brand-new material combinations, such as aluminum-based materials, Preparation of coatings on titanium-based materials or cast iron materials. Because the surface quality of the coating is significantly higher than that of ordinary laser cladding, it can be applied only by simple grinding or polishing, so the waste of materials and subsequent processing are greatly reduced. Ultra-high-speed laser melting is in terms of cost, efficiency, and thermal impact on parts. Covering has irreplaceable application advantages.
