  • DEVEOPMENT OF THE INSTITUTE :: Nontransferred Plasma Arc Spraying

            Nontransferred Plasma Arc Spraying a thermal spray process in which a nontransterred arc is a source of heat that ionizes a gas which melts the coating material and propels it to the workpiece.

            Plasma is present in any electrical discharge even one as in an ordinary arc or in a vacuum tube. It is cold plasma that excites the phosphors within a fluorescent tube.

            Today's plasma spray guns are sufficiently robust to produce temperatures from 5,000C (9,032F) to 16,000C (28,832F) for long periods. These guns are referred to as "nontransferred arc plasma generators". The generator is essentially an electric arc working in a constricted space. Two electrodes, front (anode) and rear (cathode), are contained in a chamber, as is the arc through which the effluent (the operating gas) passes.

            Typical plasma forming gases include argon, nitrogen, hydrogen and helium. They may be used either alone or in combination: viz, argon-hydrogen, argon-helium, nitrogen-hydrogen, etc.
