Powder plasma spray (also known as Welding Electrode) is the use of compression heat generated by plasma arc melting metal powder, in the surface layer and the substrate to form metallurgical bonding, with specific performance cladding layer on a surface enhancement technology. Powder plasma spray welding layer diluted with low technology, low consumption of spray materials, spray equipment, a high degree of mechanization and automation, spray speed, welding layer of the advantages of stable quality, very suitable for small area, high demand, large volume surfacing.
Materials Protection, Wuhan Research Institute of the late sixties of last century the first in China to carry out powder plasma spray equipment, technology, complete sets of spray materials, technology research, commercialization of the mid-seventies to launch series of spray equipment and spray powder. The technology used in the domestic first valve sealing surface spray, and gradually expand to other industries. After three years of continuous efforts, I have formed a mature and reliable spray equipment, spray technology, special materials, spray three systems, a number of typical products spray technology outcomes (such as the valve body seal hole surface welding technology, large-diameter valve sealing surface welding technology, large-diameter cast iron valve sealing surface spray copper and iron-based alloy technology, internal combustion engine exhaust valve into the spray cone and the top technology, composite tungsten carbide powder spray welding technology, etc.) to the domestic advanced level, has won the Ministry of Machinery Industry and Technology Achievement Award, and has long charged under the jurisdiction of domestic plasma spray technology leadership, responsible for the formulation of the powder plasma spray gun and spray supply technical conditions the national standards, access to The first field of welding technology of domestic invention patents, in the "welding", "Material Protection" and other professional journals have published several papers. Production of powder material has iron, nickel, cobalt, copper, composites five series of dozens of varieties, according to user requirements developed special powder. Developed three generations of spray equipment is widely used in machinery, metallurgy, petrochemical, shipbuilding, automobiles, mining and other industries, creating a considerable technical and economic benefits.
I have a skilled professional and technical personnel and supporting a complete spray equipment, long-term external spray process to undertake a variety of products processing business. Especially in the high-pressure spray valve sealing surface of cobalt-based alloy technology has extensive operational experience, as one of the four major power plant boiler plant of Wuhan Boiler Factory bear the high pressure valve sealing surface of the work has been sprayed up to fifth years, creating hundreds of million of economic benefits. Quality of products by users praise.
I have developed series of special and general PTA plasma spray welding powder summary of many years research experience in technology, programming reasonably high degree of automation, easy operation, flexible, can reduce the human factors on the spray quality. Overall equipment reliability, easy maintenance, support after the completion of different mechanical parts of different shapes of the spray. Plasma torch has been supporting the formation of different power and different uses of the park, outside the park, deep hole and other series, all have job stability, long life wearing parts, solder powder deposition efficiency, and can be sprayed boron and various types of non-boron iron-based, nickel, cobalt, copper alloy powder, better adapted to the requirements of the development of modern spray powder. Development of the PTA-400D and PTA-400E Series valve sealing surface plasma spray powder have been widely used in welding of large diameter high pressure valve sealing surface Welding Flux, the overall technology in domestic industry leader.
I have a complete integrated technology R & D capabilities, according to user requirements for various types of specially developed special spray equipment and spray gun, the development of various matching technology to provide users with high quality, efficient technical support and technical advice, training personnel. Plasma spray technology has a complete independent intellectual property rights, is one of the few at the same time have the equipment and technology R & D capabilities of state-owned science and technology enterprises.
