Plasma spray is a high heat thermal spray system that combines technical aspects of both flame and arc spray. Plasma spray systems were the first systems capable of creating a high enough flame temperature to reliably apply carbide coatings. This high heat is the main benefit of plasma spray and allows for the application of ceramic coatings. Plasma spray uses an electrical arc to dissociate and ionize hydrogen and argon gases. The plasma spray gun injects powder into this spray stream to apply various types of coatings
Ceramic plasma spray coatings can be used as a thermal barrier for components used in high heat environments. Plasma coatings are also wear and corrosion resistant. Plasma thermal spray also offers I.D. spray capabilities
