Plasma Spray Coating

An inert gas passes through an arc creating a plasma plume. Powder is injected into the plasma plume, which melts and propels the material onto a prepared work surface to form a coating. The plasma plume reaches temperatures of 15,000° F to more than 30,000° F however, our processing technique ensures the heat does not transfer to the part and will not cause part distortion, warping, cracking, or any changes to the base metals. The plasma process allows for the use of a wide range of coating materials: ceramics, refractory metals, alloy materials and materials containing carbides.
