Plasma spray is a thermal spray method in which a plasma jet is created by striking an arc between an anode and a cathode with a gas flowing through it. A material (feedstock) is then introduced into the plasma jet where it is highly energized, melted to a molten state and projected onto the substrate of the part being coated.
The plasma spray process offers a broad base of materials (powders) including metals, ceramics, polymers and composites.
