Once corrosive solution arrived at the substrate, galvanic corrosion occurred, and aluminum coatings acted as the sacrificialanode protecting the steel substrate from corrosion.
腐蚀介质到达基体时,将发生电偶腐蚀,铝涂层会作为牺牲阳极保护基体免受腐蚀。

The most recent developments have been in the evolution of galvanic or sacrificialanode systems.
