Thermal spray technology (part of surface process technology)

       

Thermal spraying technology is defined in the national standard GB/T18719-2002 "Thermal Spraying Terminology and Classification": Thermal spraying technology is to use a heat source to heat the sprayed material to a molten or semi-melted state, and spray and deposit it at a certain speed. A method of forming a coating on the surface of a substrate. Thermal spraying technology creates a special working surface on the surface of ordinary materials to achieve: anti-corrosion, wear-resistant, anti-friction, high temperature resistance, anti-oxidation, heat insulation, insulation, electrical conductivity, microwave radiation resistance, etc. To achieve the purpose of saving materials and energy, we call the special working surface coating, and the working method of making coating is called thermal spraying. Thermal spraying technology is one of the important components of surface process technology, accounting for about one third of surface engineering technology.
