What are the characteristics of laser cladding technology

Summary:
1. Metallurgical bonding between coating and substrate, with high bonding strength;
2. The hardness and thickness of the cladding layer are well controllable;
3. The dilution rate of the cladding layer is low, the grain size of the cladding layer is fine, the surface hardness is high, and the wear resistance is good;
4. High powder utilization rate and smooth cladding layer;
5. Low heat input results in fewer heat affected areas on the substrate;
6. Save materials, reduce costs, and promote energy conservation and environmental protection;
7. High degree of automation, capable of achieving three-dimensional automatic processing.

Laser cladding, as a new type of metal surface functional coating manufacturing technology, has been highly recognized in the market for its high cladding efficiency, good coating flatness, and low overall cost. The main characteristics of laser cladding are as follows:
1. The coating is metallurgical bonded with the substrate, with high bonding strength and good anti stripping performance;
2. The forming efficiency can reach 0.9 ㎡/h, with high melting efficiency;
3. High powder utilization rate, smooth cladding layer, can be directly processed by magic polishing without the need for turning process, saving materials and reducing costs;
4. Cladding materials are widely used, and most conventional and special metal powder materials can be fused onto the surface of metal parts.
5. High speed cladding has low heat input and deformation on the workpiece, which can effectively improve the mechanical and corrosion resistance properties of the material;
6. Compared with plasma spray welding, the dilution rate is low, the grain size of the fusion layer is fine, the surface hardness is high, and the wear resistance is good;
7. In laser cladding, the laser power density is high, the cooling speed is fast, and high melting point powder materials can be cladding. The cladding layer is thin and thick, with a thin coating of 0.1mm-0.3mm and a medium to thick coating of 0.3mm-1.5mm. Multiple layers of cladding can also be carried out;
8. It can achieve selective local repair and higher application rate;
9. High degree of automation, the entire processing process is controlled by computer, which can achieve three-dimensional automatic processing and high processing quality;
10. Energy conservation, environmental protection, and environmental friendliness; No three wastes are generated during the high-speed melting process.
