要約

The experimental study of heat transfer between a direct current electric arc and its anode is of primary importance for the understanding of mechanisms involved, for example, in plasma cutting, metal purification, extractive metallurgy, powder synthesis.... 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.
