In the Plasma Spraying Process powder is softened or melted in the plasma gas stream, which also transfers the particles to the work piece.
The plasma arc is not transferred to the work piece, it is contained within the plasma torch between an axial electrode and a water cooled nozzle. The process is operated in normal atmosphere, in a shielding gas stream (e.g. Argon), in a vacuum or under water.
Due to the high temperature of the plasma gas stream the Plasma process is especially suitable for spraying high melting point metals as well as their oxides and carbides.
Benefits of Plasma Spraying are:
Operates In Several Environments
Ideal for High Melting Point Materials
