Powders for Laser Cladding
Introduce
| Process Heat Source | High-energy laser beam |
| Characteristics | 1. A process that deposits alloys onto material surfaces with consistent results at low dilution rates. 2. Particularly suitable for high volume automated applications. |
| Process | 1. Metal powder is fed into a melt pool created by a laser beam, which deposits the molten powder onto the substrate with minimal heat. 2. The alloy is deposited onto the component surface with low dilution (<5%). Laser cladding can be fully automated, and once the parameters are selected for a specific design, consistent results are achieved for all parts. 3. The process is very flexible, and by controlling the different powder feed rates of the dual barrel powder feeder, a uniform mix of two or more powders can be achieved during the cladding process. |
| Appliocation | It can be used to enhance the wear resistance of parts or repair the worn surface of parts. |
| Typical Process Characteristics | 1. Deposition efficiency: up to 8 kg/hour 2. Suitable for automation 3. No remelting required |
| Coating | Forms a metallurgical bond with the substrate. |
