要約(英語): We investigated the fundamental electrical characteristics of pure water using coated spherical electrodes with diamond-like carbon (DLC). When the spherical electrodes made of chromium steel, which is one of metals, were put in pure water, the resistivity of pure water decreased 23% compared to pure water alone after 120 minutes. On the other hand, when the spherical electrodes made of chromium steel coated with DLC with a thickness of 1 μm were put in pure water, the decrease in resistivity of pure water could be suppressed to 10%. Furthermore, with chromium steel spherical electrodes coated with DLC, the lightning impulse breakdown voltage of pure water was 16% higher than that with the bare chromium steel spherical electrodes.
