Thermal spraying technology is a common surface treatment technology

       Thermal spraying technology has a history of decades of development in my country. Since its introduction into China, its development momentum has been very rapid, and it has developed into the most important and commonly used technology in surface treatment engineering today. Thermal spraying technology occupies such an important position in the surface treatment project, how is it manifested? Today will be popularized by Feize Technology for everyone.

  Thermal spraying technology is an important technology in surface treatment engineering. It can strengthen and protect the surface of the workpiece. It has a wealth of spraying materials and can give the surface abrasion resistance, corrosion resistance, oxidation resistance and high temperature wear, heat insulation, insulation, etc. This kind of function is unique and easy to operate, flexible, especially suitable for on-site construction and partial repair of workpieces. Thermal spraying technology is not only an effective method for surface strengthening and pre-protection of new equipment, but also an economical and effective method for on-site construction and partial repair of workpieces. Over the years, it has been widely used in various industrial fields and various general mechanical parts. , Such as the strengthening and repair of various shafts, valves, fans, etc., and has achieved significant social and economic benefits. In the past ten years, thermal spray technology has developed rapidly at an annual growth rate of 5-10%. So far, the global thermal spray application output value has reached 1.35 billion US dollars.

With the continuous progress of thermal spraying technology, such as the advent of supersonic flame spraying and supersonic plasma spraying technology, as well as the continuous development of various new spraying materials, the weaknesses of low bonding strength and poor impact resistance of thermal spray coatings in the past have been overcome. The application of the new thermal spraying method has brought a qualitative leap in the quality of the coating. The porosity of the coating can be reduced to 0.5%-1.0%; the bonding strength of the coating can reach 70MPa-140Mpa. With the continuous progress of industrial production technology, the application range of thermal spraying technology in various industrial fields will continue to expand.
