Laser cladding uses a high-energy laser pointer as a heat source. Alloy powder is used as coating material. The alloy powder is synchronously acted on the surface of the workpiece to melt rapidly by laser irradiation to form a molten pool. Rapidly solidify to form a dense, uniform and controllable metallurgical bonding layer to improve the wear resistance, corrosion resistance, high temperature resistance and oxidation resistance of metal parts. Not only can the failed parts be restored to use, but also can be significantly extended. The service life of the parts. The new part modification uses laser pointer cladding technology to deposit a layer of special performance coating on the designated area of the workpiece surface, which can improve the surface performance of the workpiece, make the important components have the characteristics of super wear resistance and corrosion resistance, and greatly improve the component Service life. After the ball valve is produced in the chemical industry, the surface of the cladding is modified. The thickness of the cladding is 1.2mm, there are no defects such as pore cracks, and it has high corrosion resistance requirements. The hardness of the cladding layer is above 55HRC.
Repair of old parts, petrochemical industry, the equipment has been in a harsh working environment for a long time, it is easy to cause severe corrosion and severe wear and tear of parts, and even lead to the complete scrapping of large and expensive parts, and green laser pointer cladding technology is some expensive parts And the repair of inconvenient replacement parts provides the possibility that the repaired parts will be double the strength of the original parts, and save the cost of newly purchased parts for enterprises. Parts and components that often cause problems in chemical equipment include valves, pumps, impellers, journals, wheel discs, bushings, bushings, etc. of large rotors. Ball valves and shaft parts in the chemical industry are repaired after cladding. The thickness of the cladding is required to be 1mm, and there are no defects such as pore cracks. Has a certain corrosion resistance, the hardness of the cladding layer is above 50HRC.
