Laser cladding uses a high-energy laser as the heat source and alloy powder as the cladding material. The alloy powder is irradiated by the laser and simultaneously acts on the surface of the workpiece to quickly melt to form a molten pool, and then rapidly solidify to form a dense, uniform and thickness-controllable metallurgical bonding layer. Improving the wear resistance, corrosion resistance, high temperature resistance and oxidation resistance of metal parts can not only restore the use of failed parts, but also significantly extend the service life of new parts.
By laser cladding technology, a coating with special properties can be applied to the specified area of the workpiece surface, which can improve the surface performance of the workpiece, make the important parts have the characteristics of super wear resistance and corrosion resistance, and greatly increase the service life of the parts.
In the petrochemical industry, the long-term harsh working environment of equipment can easily cause severe corrosion and violent wear of parts, and even lead to complete scrapping of large and expensive parts. Laser cladding technology provides some expensive parts and inconvenient replacement parts. Component repair provides the possibility, the strength of the repaired component will be twice that of the original component, and it will save the company the cost of purchasing new components.
Compared with traditional processing methods,fiber laser cladding machine has the following advantages:
1.The laser cladding has a small thermal influence zone on the substrate and the workpiece deformation is small;
2.Metallurgical bonding can be realized between the cladding layer and the matrix material, and the cladding material has a low dilution rate;
3.The cladding layer has small grains and compact structure, which can obtain high hardness, wear resistance and corrosion resistance;
4.It can achieve selective partial fine repair, effectively reducing repair costs;
5.The powder material system has high adaptability. Most of the conventional and special metal powder materials can be fused to the surface of metal parts.
In addition, laser cladding machine can also be applied to other industries such as iron and steel metallurgy, automobiles, engineering machinery, mold manufacturing and shipbuilding, and has a very broad application prospect. If you want to know more about our products, please contact senfeng.
