LPPS – Low Pressure Plasma Spraying

Low pressure plasma spraying provides a significant increase in the bond strength, density and purity of the coatings compared to atmospheric plasma spraying.

A low pressure plasma coater basically consists of the following components:

Plasma gun and control unit (plasma gases, powder feed gas, powder supply, current, voltage, cooling water, etc.), power supply (DC), HF-plasma ignition, powder feeders, vacuum tank with motion system for workpiece and plasma gun, filter system, pumping station.

Furthermore, a prechamber is useful where, parallel to the coating process, preheating of the next workpiece takes place. In addition, the relatively big vacuum tank of the main chamber does not have to be evacuated with each change of workpiece.
