陰極防蝕用犧牲陽極材料的化學分析及其電化學性能測試之研究

Chemical Analysis and Electrochemical Performance of Sacrificial Anode Alloys for Cathodic Protection

陰極防蝕用犧牲陽極材料的成份、電化學性能及其測試方法，目前國內標準規範尚未頒布，材質分析方面，取最常用到的鋁系及鋅系合金陽極為測試樣品，以AA、AE 呈色法、及ICP儀做分析測試；電化學性能測試方面，介紹數種方法，並以鋁系合金為測試樣品，依據JSCE實驗方法，進行人工海水，天然海水，與3%氯化鈉溶液作測試實驗以比較其差異；期望這些數據與結果對相關標準規範具參考的助益。

The industrial standards for the composition, electrochemical performance and related testings of the sacrificial anodes have not been established in this country. Regarding the component analysis, Al and Zn anodes have been chosen as the test samples by means of a series of instrumental analysis, e.g., AA, AE, colorimetry and ICP. A number of methods have been applied including Al anode as the test sample in artificial and natural seawater and 3 % NaCl solution according to JSCE experimental method. The results obtained are valuable and can thus be concluded that product specifications and testing procedures of the anode materials should be standardized and the efforts should be made towards a better cathodic protection design with safety.
