Laser Cladding
Laser Cladding Technology: Principles and Advantages
Laser cladding ( Laser Cladding ) is an advanced surface modification technique that uses a high-energy laser beam to simultaneously melt metal powder and the substrate, followed by rapid solidification to form a dense, high-performance cladding layer.
Process Characteristics
1. High-precision joining: laser energy is highly concentrated, resulting in a small heat-affected zone, enabling 0.1-2mm Precision cladding of thickness.
2. Strong bonding: The cladding layer is metallurgically bonded to the substrate, with a bond strength of 400MPa Above, porosity < 0.5% 。
3. Wide applicability: Supports surface repair and strengthening of various substrates, including steel, titanium alloys, and nickel-based superalloys.
4. Eco-friendly and efficient: material utilization rate exceeds 95% , reduce traditional electroplating / Pollution issues in thermal spraying.
Core Application Areas
- Industrial Repair: Repairing Worn Gears, Shafts, Molds, and More / Corrosion-resistant components, reduced costs 30%-50% 。
- Additive Manufacturing: Direct Fabrication of Complex Aerospace Structural Components ( DED Craftsmanship).
