Abstract

Ar/N₂ plasma flames from the microwave-induced atmospheric jet plasma were constricted using aluminum tapered gas nozzles (with orifice diameters of 0.5, 1, and 2 cm). The Ar/N₂ plasmas were generated at forward powers of 400-1200 W with Ar and N₂ gas flow rates of 3-6 and 1-10 LPM, respectively. The effect of the orifice diameter of the nozzles on the ignition power, gas temperature, and contact angle and substrate temperature of surface treated aluminum were determined. It has been observed that the orifice diameter affects the ignition power needed by the plasma flame. The gas temperature of the plasma flame and contact angle and substrate temperature of the aluminum generally decrease with decreasing orifice diameter.
