Abstract

To produce the micro scale oxidation film on the metal surface, this study use a radio frequency (RF) electromagnetic oscillation circuit and a high voltage pulse discharge circuit combined at atmospheric pressure, which generated a discharge micro plasma beam. The rough metal surface is irradiated by the plasma directly. After the irradiation on the metal surface for a few minutes, the rough metal surface got smooth and clean with lots of micro scale oxidation film on it. Experimental results showed that the oxidation film on the metal surface can effectively improve the metal surface of producing rust in a long time, thereby, improving the metal surface performance.
