Atmospheric and Shrouded Plasma Spray

Product Details

(Click to enlarge image) Atmospheric Plasma Spray is the most flexible of thermal spray processes with ability to coat virtually any material while achieving excellent control of coating thickness and surface characteristics. A strong electric arc is generated between a positively charged pole (anode) and a negatively charged pole (cathode). This ionizes the flowing process gases into the plasma state. Powdered feedstock material is injected into the plasma jet, melting the powder particles and propelling them to the surface of the workpiece.

Shrouded Plasma Spray offers the versatility of atmospheric plasma spray within an inert atmosphere. A shroud of protective gas surrounds the plasma jet and reduces the amount of oxygen available to oxidize the material being deposited. Shrouded Plasma Spray is used for oxygen-sensitive applications where functionality, size and budget do not require vacuum plasma spray deposition.

Applications:
Oxidation-resistant coatings
Thermal barrier coatings
Corrosion-resistance
Neutron absorbing materials
Medical device and implant coatings
