Abstract

See full text

Plasma applications are disclosed that operate with argon or helium at atmospheric pressure, and at low temperatures, and with high concentrations of reactive species in the effluent stream. Laminar gas flow is developed prior to forming the plasma and at least one of the electrodes can be heated which enables operation at conditions where the argon or helium plasma would otherwise be unstable and either extinguish, or transition into an arc. The techniques can be employed to clean and activate a metal substrate, including removal of oxidation, thereby enhancing the bonding of at least one other material to the metal.
