Laser cladding technology can not only restore the appearance and size of damaged parts but also make their performance meet or exceed the level of new products. The cladding layer and the matrix are bonded by metallurgy, and the bonding strength is high, not less than 95% of the original matrix material. Single-layer cladding thickness is 0.2-2mm, wide adjustable range. During laser processing, only slight melting occurs on the surface of the substrate, and the micro-melting layer is 0.05~0.1mm. The heat-affected zone of the base is very small, generally 0.05~0.1mm. There is no coarse casting structure in the cladding layer and matrix. The cladding layer and its interfacial structure are dense, the grains are fine, and there are no defects such as cavities and inclusion cracks.
the advantages of choosing laser caldding
1. The strength of the repaired parts can exceed the strength of the original matrix, the service life is increased by 1.5-3 times, and the repair cost is less than 1/5 of the replacement price.
2. Greatly shorten the maintenance time, to solve the problem of rapid repair of parts that must be solved for the continuous and reliable operation of major complete sets of equipment in large enterprises.
3. The key parts surface laser cladding super wear-resistant corrosion-resistant alloy, can greatly improve the service life of parts without deformation.
Laser cladding technology is an advanced surface engineering technology, which uses high-energy laser beam to melt metal powder and matrix surface quickly and metallurgically to form a coating with excellent performance integrated into the substrate. For example, the working conditions of oil fields are relatively harsh, and many metal parts work under heavy loads for a long time, accompanied by corrosion, friction and wear, leading to premature failure and shortening their service life. Stopping production for inspection and replacing new parts not only increases the cost of materials but also affects the production of oil fields, resulting in many losses. The wearing clearance of friction pairs of many metal parts in the oil field is in the order of nearly a millimeter. However, the conventional surface technology treatment layer is thin, and the surface repair of worn parts is difficult, which limits the application range of these technologies. Therefore, laser cladding technology can be applied to oil drill pipes, sucker rods, oil pipelines and other fields to improve its corrosion resistance, wear resistance, high-temperature resistance and other properties. It extends its service life , reduce maintenance costs, and improves oil production efficiency.
