On April 29, the first production line of the new laser cladding alloy material project was put into operation in the equipment manufacturing park of Qinghai National High-tech Industrial Development Zone. The project was led by the Aerospace Information Research Institute of the Chinese Academy of Sciences.
Laser cladding alloy material is a general name for materials consumed during cladding. It belongs to new metal alloy materials. It is used to melt different additives at the same time with the surface of the substrate by laser irradiation or melting, and forms intermolecular bonds with the surface of the substrate This will significantly improve the wear resistance, corrosion resistance, heat resistance, oxidation resistance, salt and alkali resistance of the substrate surface, and significantly improve the mechanical properties such as tensile strength and yield strength of structural steel. This material has outstanding advanced nature, environmental protection and extensive promotion. It is the basic material for high-end equipment manufacturing, and it is also a consumable material. The laser cladding alloy material resources can be processed to produce flux-cored wire products. This product is the "sewing thread" and "adhesive" of steel. It is mainly used in equipment manufacturing, shipbuilding, petroleum and petrochemicals, infrastructure construction, and energy. The connection and reinforcement of key parts in transportation, marine engineering and other fields have an irreplaceable special effect on the quality of equipment manufacturing, and the market has a bright future.
The high-strength, high-wear-resistance, heat-resistant, laser-clad alloy materials developed and produced by the laser cladding technology team of the Chinese Academy of Sciences are important varieties of cladding materials with high technical difficulty and wide application scope. It has achieved remarkable application results and is a classic representative of new materials in the Made in China 2025 plan.
The project was undertaken by QHZK Laser Cladding New Materials Co., Ltd. According to the company's general manager Ma Youzhen, Qinghai has a dry climate and is upgrading its green development model, which is very suitable for the production of environmentally-friendly new laser cladding alloy materials. At the same time, laser cladding and high-speed spraying are additive manufacturing and remanufacturing technologies. They are used in the maintenance and repair of large machinery, and can serve many industrial enterprises in Qinghai and even the northwestern region. Implementation.
