Laser Cladding is a surface modification technology that cladding alloy powder, ceramic powder or composite material to metal cladding by high-energy laser beam to form metallurgical bond with the matrix, thus significantly improving the wear resistance, corrosion resistance, heat resistance, oxidation resistance and other properties of the material surface, or realizing the repair and remanufacturing of failed parts.

Process flow Preset: The cladding material is laid on the surface of the matrix in advance, and then melted by laser beam scanning. 

Synchronous: At the same time of laser irradiation, the material is directly sent into the melt pool through the powder feeding device (mainstream way). 

Post-treatment: Heat treatment may be performed after cladding to optimize microstructure properties. Core equipment Laser: Commonly used CO₂ laser, fiber laser, disc laser (high power, high efficiency). 

Auxiliary system: powder feeding mechanism, cooling system, CNC workbench, etc.

Process characteristics High bonding strength: the cladding layer is metallurgically combined with the matrix, and the strength can reach more than 90% of the base material. 

Low dilution rate: the dilution rate of the cladding layer is less than 5%, which can retain the original properties of the material. 

Small thermal deformation: laser energy concentration, small heat affected zone, suitable for precision parts. Wide material compatibility: Support nickel base, cobalt base, iron base alloy, tungsten carbide, ceramics and so on. 

Green environmental protection: no harmful substances emissions, in line with the concept of sustainable manufacturing.
