The thermal spraying technology of Osaka Fuji Industrial, active in a wide range of industrial fields.

In an operating gas such as argon or helium, a voltage is applied between a tungsten cathode and a copper nozzle anode, generating a direct current arc that dissociates and ionizes the operating gas, continuously producing a plasma arc. This is then constricted by a cooled nozzle, ejecting a high-temperature, high-speed jet of over 15,000°C. By feeding powder into the plasma jet and accelerating it while melting, it is possible to spray high melting point materials such as ceramics. Furthermore, the plasma jet stream can blow molten particles onto the material at high speed, allowing for the formation of high-quality spray coatings compared to other spraying methods, and there is a wide variety of spray materials available. ● For more details, please download the catalog or contact us.
