Web10 de set. de 2024 · In the following phase of low current, the radiation emitted by the arc plasma no longer causes sufficient wall ablation to sustain the high pressure in the nozzle (cf. spectrum at 0.7 ms before CZ). The consequences are a reversal of the gas flow direction, disappearance of the fluorine line, and a spectrum dominated by C II line … WebThe concentration of dissolved oxygen was changed and the results compared.
