    • An electrolytic electrode having an interlayer having more excellent peeling resistance and corrosion resistance and longer electrolytic life than conventional electrolytic electrodes and capable of flowing a large amount of current at the industrial level and a process of producing the same are provided. The electrolytic electrode includes a valve metal or valve metal alloy electrode substrate on the surface of which is formed a high-temperature oxidation film by oxidation, and which is coated with an electrode catalyst. The high-temperature oxidation film is integrated with the electrode substrate, whereby peeling resistance is enhanced. Further, by heating the high-temperature oxidation film together with the electrode catalyst, non-electron conductivity of the interlayer is modified, thereby making it possible to flow a large amount of current.
    • 提供一种具有中间层的电解电极,其具有比常规电解电极更好的耐剥离性,耐腐蚀性和更长的电解寿命,并且能够在工业级流动大量电流及其制造方法。 电解电极包括阀金属或阀金属合金电极基板,其表面通过氧化形成高温氧化膜,并且涂覆有电极催化剂。 高温氧化膜与电极基板一体化,从而提高耐剥离性。 此外,通过与电极催化剂一起加热高温氧化膜,改变了中间层的非电子传导性,从而可以流过大量的电流。
