What is the Laser Cladding Process
The laser cladding process is a precision surface engineering technology where a high-powered laser melts a layer of metallic or composite material onto a substrate. The resulting bond creates a dense, wear-resistant coating that enhances the component’s durability and functionality, which applies to various industrial surfaces.
How Does Laser Cladding Work?
The process begins by delivering a cladding material onto the component’s surface, typically in powder or wire form. A high-energy laser melts this material, fusing it seamlessly with the substrate. By carefully controlling the laser beam’s intensity and movement, the laser cladding process achieves an ultra-smooth and uniform layer tailored to the application’s needs.
The ability to independently mix and control the feed rates of two or more powders makes laser cladding a versatile technique for creating heterogeneous components or functionally graded materials. The localised fusion and mixing within the melt pool also enable microstructural-level customisation, allowing clad materials to be specifically engineered for optimal performance in targeted applications.
Advantages of Laser Cladding
- Fusion bond – metallurgical bond, not a surface coat (mechanical bond)
- Entirely different from spray metal & HVOF reclamation processes
- Can be applied to any machined surface in a static or dynamic role, including bearing journals and seal surfaces
- Very low weld dilution – doesn’t dilute the parent material (typically 3%)
- Low heat input – allows rectification of journal on electrical rotors without removing windings
- Isolate and laser-damaged area only – no masking or dipping
- Reclaim components that would otherwise be beyond economical repair with minimal workpiece distortion
- Dense microstructure – not porous
- Chemically clean – more environmentally friendly than chroming and HVOF
- Thin or layered coating – single or multiple passes
- Minimal after machining – one to two passes then linish
- Fast turnaround – compared to chrome or new
- Wide material selection – Stainless 431, Stainless 316, Stellite-6, Tungsten Carbide and more
