<p>The purpose of this study is to establish a multiphase AC arc (MPA) system for nanomaterial fabrication without electrode erosion issues. An innovative method to generate MPA with diode rectification was proposed to solve electrode erosion. Multi-diodes were placed between the electrodes and the transformer. Then, the electrodes were divided into pairs of W cathode and Cu anode. The electrode erosion rate in diode-rectified MPA was less than one-third of that in conventional MPA. The high-speed imaging of the electrode region revealed that the electrode temperature was successfully decreased in diode-rectified MPA due to its polarity characteristics. Moreover, the high-speed imaging of arc phenomena suggested that the stable arc discharge was successfully generated in diode-rectified MPA. Obtained results indicated that the diode-rectified MPA enabled us to establish nanomaterial fabrication process at high-productivity.</p>
