Spraying environment
Air plasma spraying (APS)
Controlled atmosphere plasma spraying (CAPS)
Either filled with inert gas or evacuated
A gas, usually argon, but occasionally including nitrogen, hydrogen, or helium, is allowed to flow between a tungsten cathode and a water-cooled copper anode
An electric arc is initiated between the two electrodes
The arc ionizes the gas, creating a high-pressure gas plasma.
Powder is both heated and accelerated by the high-temperature, high-velocity plasma gas stream - Наука та технологія
