Plasma Coatings (Non-Transferred Arc)
In the non-transferred arc process, an arc is established between the electrode and the constricting nozzle. The non-transferred arc is then utilized as the source of dissociation, which ionizes the gas stream, melting and propelling the coating material to the work piece. Coatings can range in thickness from a few micrometers to several millimetres. Because of the extreme temperatures reached with plasma, often up to 30,000°F, Longevity Plasma is the coating process of choice for applying high melting point materials such as chromium oxide, aluminum oxide, other ceramics as well as refractory materials.
Plasma spray coating can be performed in a wide array of conditions and is an adaptable process.
