The ultimate objective of this work is to produce nanometric particles from the condensation of metallic vapors obtained by controlled evaporation of the anode material. A transferred arc reactor was designed to generate a stable arc jet, less than 3mm in diameter, using pure argon, argon-hydrogen mixture or nitrogen as plasma forming gases (4−10 slm) and power supplied by a current regulated source (I = 15−40A). According to the nozzle internal diameter used to constrict the arc, the jet velocity is over 1000 m.s−1 and the angle between the jet axis and the normal to the anode surface can be changed from 0° to 85°. Arc voltage fluctuations and heat power to the anode were measured for various experimental conditions, leading to different attachment modes, as testified by video-records. %8 2004-12-01
