Description :

Plasma Spray process:

The plasma spray system is versatile process in thermal spray systems and by using this system ceramics, carbides, metals and plastics can be applied onto base materials for wear and corrosion protection, electrical insulation, thermal insulation, repair, and restoration.

Process description:

In plasma spray system, an electric arc created between two fixed electrodes. Process gasses (argon, nitrogen, hydrogen, helium) flows around the cathode and through the anode which is shaped as a constricting nozzle. The plasma is initiated by a high voltage discharge which causes localised ionisation. Powder is fed into the plasma flame most commonly via an external powder port mounted near the anode nozzle exit. The powder is so rapidly heated and accelerated to deposit on work piece.
