通过动电位技术和连续监测电偶电流，研究了碳钢和六种电镀涂层材料（包括 SIGAL®-铝、镉、锌以及与铜、镍和锡的双相组合）之间的电偶相互作用。这里报告了 12 个电偶浸入不同酸度的氩气和空气饱和硫酸盐和氯化物溶液中的结果。在潮湿的城市、工业和海洋大气中，钢不仅可以受到镉和锌的阴极保护，还可以受到 SIGAL® 铝的阴极保护。双面涂层中的超薄中间层，例如镍或锡对铝顶层和钢基底的影响实际上可以忽略不计。
Galvanic interaction between carbon steel and six galvanic coating materials including SIGAL®-aluminum, cadmium, zinc and duplex combinations with copper, nickel and tin has been studied by potentiodynamic techniques and continuous monitoring of the galvanic current. Results for 12 galvanic couples are reported here for immersion in argon and air saturated sulfate and chloride solutions of various acidity. Steel can cathodically be protected not only by cadmium and zinc, but also by SIGAL®-aluminum, in moist urban, industrial, and marine atmospheres. Ultrathin intermediate layers in duplex coatings, of e.g. nickel or tin, have practically negligible influence on the aluminum top layer and the steel base.
