diener electronic : Plasma spray coating


	Plasma spray coating Method for the coating of surfaces with metals and ceramics. Herein, the powdered coating material is introduced into a gas stream of a high energetic plasma (about 12000 K). The coating material melts and is propelled onto the substrate’s surface where it solidifies immediately. Particularly useful in the manufacture of hard protecting coatings with well-defined coating thickness. The process can be applied under ambient pressure (air plasma spraying – APS) or in vacuum under an inert gas (vacuum plasma spraying – VPS).
