How plasma spraying works
We use a non-transferred arc plasma process. An arc between an electrode and a constricting nozzle ionizes the gas stream into a high-energy plasma reaching up to 30,000 °F. Powder injected into the plasma melts and is propelled onto the workpiece, forming coatings from a few micrometers to several millimeters thick.
What we apply
Plasma is our process for high-melting-point materials: chromium oxide, aluminum oxide and other ceramics, and refractory materials. We also use it to produce abradable coatings for clearance control in rotating machinery.
Applications
- Clearance control: abradable coatings hold tight clearances in rotating machinery such as gas turbines.
- Thermal barriers: shield gas turbine blades, engine parts and industrial furnace linings from extreme heat.
- Energy equipment: heat and corrosion resistance for boiler tubes and wind turbine parts.
- Valve parts: protection from corrosion, wear and high temperatures in automotive, oil and gas, and industrial systems.
- Chemically inert surfaces: for chemical processing and medical equipment.
- Semiconductor manufacturing: wafer processing equipment exposed to chemicals and high temperatures.
Finished in-house
We diamond grind, diamond lap or diamond super finish plasma coatings to your specifications. Plasma-sprayed ceramics can be ground and lapped to a 4 Ra finish.
