Cooperative project categories: laser cladding high-temperature and wear-resistant coatings, 3D printing injection molds, key components of marine engineering equipment, etc.

Laser cladding technology aims at the on-site repair needs of large-scale key components in the fields of steel, petrochemical, electric power, metallurgy, automobiles, etc. (such as steel rolling mill arches, power plants, petrochemical large rotors, automobile die-casting molds, etc.). Processing integrated equipment, materials, and technology, focusing on the development of laser cladding powder materials such as wear resistance, high temperature resistance, oxidation resistance, and corrosion resistance, breakthroughs in the control of cracks in high wear resistance and high hardness coatings, large-area repair of tissue defect control, large and thin Applied technologies such as wall deformation control.

Aiming at the problem that the key parts of smelting aluminum, copper, lead, zinc and other non-ferrous metals are severely corroded by molten metal, laser cladding technology is used to develop coating materials and preparation processes that add Mo, W and oxide ceramics, and develop metal resistance A protective coating with excellent fusion corrosion performance, and is the first to realize industrial application on the representative electrolytic aluminum anode steel claw with serious fusion corrosion, and then popularize and apply it in aluminum, copper, lead, zinc and other smelting industries.

Additive manufacturing (3D printing) is an advanced manufacturing technology that integrates intelligence, digitization, informationization, and greenization. At present, with the continuous deepening of research and development of additive manufacturing and the increasingly high performance requirements of additive components, the weakness of basic research in its application has been highlighted, and a number of key core technologies are urgently needed to be broken through. For example: the porous structure of artificial joint implanted prostheses, complex cooling channels inside the conformal cooling mold, complex structural design problems of high-performance metal components such as aviation blades; metallurgical quality and mechanical performance control of high-performance additive manufacturing metal structural parts And the establishment of evaluation standards and technical specifications.

In response to the demand for 3D printing technology in molds and other fields, develop laser 3D printing technology for parts such as conformal cooling runners of injection molds, realize rapid additive manufacturing of complex precision parts, and promote the application of laser 3D printing technology in injection molds and other fields .

The marine environment is a highly corrosive environment, which is more than 10 times more serious than conventional land. Corrosion protection of related materials runs through the whole process of marine engineering. It also targets a large number of components in marine engineering equipment such as offshore platforms, drilling, oil production, ships, and offshore wind power. It only needs anti-corrosion, but also gives higher comprehensive performance, such as wear resistance, high hardness, friction reduction, self-lubrication and high temperature resistance. According to statistics, 30% of failures of marine engineering components are caused by corrosion, and 70% are caused by mechanical wear. Laser surface modification technology is one of the core technologies to solve the remanufacturing of important systems such as offshore oil and gas drilling systems, offshore ships and carrier aircraft. It can effectively solve the problem of abrasive wear caused by quartz particles in drilling systems (mud pumps, drill pipes, drill bits, drill collars, centralizers, ball valves, etc.). Marine ships (blade piston cylinder liners of power systems, transmission system shafts, propulsion devices, etc.) The problems of corrosion and wear of propellers, etc., as well as the low life of carrier-based engine systems (blades, stators, rotors, etc.) in supercritical conditions, quickly restore the functions of various marine engineering systems, and improve support and reliability.
