Galvanic corrosion of Al alloys coupled to stainless steel decreased in the order Al-5%Mg>Al-5%Ca>99.98%Al>Al-1%Mg>Al-1%Ca>Al-1%Mn>Al-5%Mn. Results of the galvanic anode test showed that the galvanic efficiency of Al-1%Mn and Al-1%Ca was higher than that of the other Al alloys. ...
Dealloying occurs when one or more components of an alloy are more susceptible to corrosion than the rest, and are preferentially dissolved. The most important example of dealloying is the removal of zinc from brass, known as dezincification. Another common example is graphitic corrosion, which ...
Although hot-dip galvanized coatings offer envelope protection for steel, zinc contained in the coating will also safeguard the steel cathodically in case the coating is destroyed and the bare steel exposed. Preventing Corrosion in Galvanized Steel The galvanized coating’s rate of consumption will be...

Galvanizing followed by passivation of fasteners is a procedure which has proven itself in terms of both corrosion resistance and appearance.
