Outline of Final Research Achievements

We demonstrate a method of metal surface coloring via oxidation by irradiating atmospheric pressure plasma. The atmospheric pressure plasma is generated via dielectric barrier discharge, which consists of an inverter power supply and electrodes covered with dielectric. A copper plate is used as a sample for surface coloration with the proposed technique. After plasma irradiation, the sample is observed, and the chemical composition ratios across its surface and depth are analyzed using X-ray photoelectron spectroscopy and glow discharge spectroscopy, respectively. We find that the surface color slightly changed from that of natural copper to that of gold after plasma irradiation. The oxygen ratio over the depth of the copper plate increases as a function of the duration of the irradiation. The chemical composition ratios of CuO, Cu2O, and Cu(OH)2 are confirmed from the XPS analysis with a Gauss–Lorentz fitting function.
