目前,外加电源用电极材料有不溶性碳系、高硅铸铁系、磁性氧化铁系、铁氧体系、铅合金系、镀铂钛系与 DSE 系等材料。电极材料的选择对电化学保护的经济性有极大的影响,尤其是电极的耐蚀性、电阻与机械强度是决定经济性的重要因素。其中,电阻大小、机械强度等已有各种文献记载,而有关在长期腐蚀试验中使用的阳极材料之耐蚀性的资料却非常少,福谷的关于电化学保护用难熔性电极的论述,对撰写这类论文有很大帮助。
Currently, the power source electrode materials are insoluble carbon, high silicon cast iron, magnetic iron oxide, ferrite, lead alloy, platinum-plated titanium and DSE Department and other materials. The choice of electrode material has great influence on the economy of electrochemical protection, especially the corrosion resistance, the resistance and the mechanical strength of the electrode are the important factors that determine the economy. Among them, the resistance size, mechanical strength, and the like have been documented in various documents. However, there is very little information on the corrosion resistance of the anode material used in the long-term corrosion test. Fugu’s discussion on the use of refractory electrodes for electrochemical protection, It is a great help to write such a paper.
