What is thermal spraying?

The "melt" in thermal spraying means to melt, and the "spray" in thermal spraying corresponds to collision and deposition!

Thermal spraying is a type of surface modification technology that involves heating metals or ceramics to a molten or semi-molten state, then colliding and depositing them onto a material surface to form a coating. The "melt" in thermal spraying refers to the act of melting, while the "spray" corresponds to the collision and deposition. Therefore, to create a good thermal spray coating, a high-temperature state is necessary to achieve sufficient melting, along with a high-speed state for spraying the particles. In the film formation process of thermal spraying, the molten particles collide with the substrate and simultaneously flatten out. Some particles may also splatter as droplets. The coating is formed as the molten raw material particles layer upon each other. 【Various Thermal Spraying Methods】 ■ Water Plasma Spraying ■ Gas Plasma Spraying ■ High-Speed Flame Spraying ■ Arc Spraying ■ Flame Spraying *For more details, please refer to the PDF document or feel free to contact us.
