Laser cladding metal powder
Laser Cladding Technology: Principles and Advantages
Laser Cladding (Laser Cladding) is an advanced surface modification technology that uses a high-energy laser beam to simultaneously melt metal powder and the substrate, rapidly solidifying to form a dense, high-performance cladding layer.
Process Characteristics
1.High-precision bonding: The laser energy is concentrated, the heat affected zone is small, and it can achieve0.1-2mmprecise cladding of thickness.
2.Strong bonding force: The cladding layer and the substrate are metallurgically bonded, with a bonding strength of400MPaor more, and porosity <0.5%。
3.Wide applicability: Supports surface repair and strengthening of various substrates such as steel, titanium alloys, and nickel-based superalloys.
4.Environmentally friendly and efficient: Material utilization rate exceeds95%reducing pollution problems of traditional electroplating/and thermal spraying.
Core Applications
-Industrial repair: Repairing worn/and corroded parts such as gears, shafts, and molds, reducing costs by30%-50%。
-Additive manufacturing: Used for direct forming of complex components in aerospace (DEDprocess).
-Surface strengthening: Improving the wear and corrosion resistance of parts such as oil drills and hydraulic rods.
