Comparison of advantages between traditional cladding and fiber lasers
Nowadays, maintaining market competitiveness requires reducing costs, improving efficiency, and maintaining stable part quality, which traditional technologies cannot meet. More and more manufacturers are shifting from traditional cladding technology to using fiber laser cladding
Plasma Cladding
After plasma spraying and melting, the bonding strength is low and the coating is easy to peel off
Laser Cladding
Laser cladding has advantages such as lower dilution rate, better processing flexibility, and less thermal impact on the workpiece
Thermal Spraying
Although the deposition rate of thermal spray coating is high, the powder utilization rate is only 50%. The coating has a porosity of 1% to 2%, and the corrosive medium will corrode the substrate through these voids. Thermal spraying is prone to generating noise and dust pollution during work, which affects the environment and the health of personnel
Laser Cladding
The coating prepared by laser high-speed melting has a dense and non porous structure, and the coating is metallurgical bonded to the substrate, resulting in high bonding strength
Surfacing
Surfacing technology can prepare high-quality and defect free metal coatings, with high deposition efficiency accompanied by high energy input, which can induce the transformation of the microstructure and properties of the substrate material and thermal damage
Laser Cladding
The high-speed laser cladding method absorbs most of the energy by the powder, resulting in less heat input to the substrate and relatively smaller heat affected zone and thermal deformation, making it more effective for cladding thin-walled and thin plates
