A picture to understand the application of thermal spray processing technology

     Thermal spraying technology has been used for nearly a hundred years since Dr. MUSchoop of Switzerland completed the initial molten metal spraying device in 1910. The coating is mainly used for spraying decorative coatings, spraying aluminum wire and zinc with oxygen-acetylene flame or electric arc. Line master. In the 1930s and 1940s, with the advent of flame and electric arc wire and flame powder spray guns, thermal spraying technology developed from the initial spray decorative coating to repairing mechanical parts with steel wire, spraying aluminum or zinc as steel coating. In the 1950s, explosive spraying technology and subsequent plasma spraying technology were successfully developed. Thermal spraying technology has been widely used in aerospace and other fields. Self-fluxing alloy powders have been successfully prepared, so that the coating remelting process can eliminate pores in the coating, and It is possible to realize metallurgical bonding of the substrate, expanding the thermal spraying

area.

    The supersonic flame spraying technology was successfully developed in the early 1980s and was widely used in the early 1990s, which expanded the application of WC-Co cemented carbide coatings from aeronautics to various industrial fields. High-energy plasma spraying technology with power up to 200kW, supersonic plasma spraying technology, and axial powder-feeding plasma

It is the emergence of high-efficiency supersonic plasma spraying technology, which provides a powerful means for further effective use of thermal spraying technology in various industrial fields. Thermal spraying technology as a technology involves a wide range of technology, relatively simple and flexible processing technology, and a wide range of applications. Modern processing technology with great economic benefits

The surface has the functions of wear resistance, corrosion resistance, heat insulation, heat resistance, conductivity, insulation, erosion resistance, oxidation resistance, friction reduction, lubrication, and radiation protection. Not only can it be used for machine compounding and surface strengthening, but also for manufacturing. Due to the wide selection of spraying materials, it is not limited by the alloying of the overall material, and it is easier to obtain various ceramic or cermet coatings and various functional coatings, and the amount of materials used for the coating is less than that of the overall high-grade materials. Compared with the overall improvement of the material, it is undoubtedly possible to use precious materials boldly, and the cost will not increase much, but the surface performance of the material can be greatly improved, and the parts repaired by thermal spraying can reach or even exceed the new products by several times.
