    Galvanic Corrosion an overview | ScienceDirect Topics

    Galvanic corrosion occurs when two different metals have physical or electric contact with each other and are immersed in a common electrolyte or when the same metal is exposed to an electrolyte with different concentrations. In a galvanic couple, the more active metal (anode) corrodes at an accelerated rate and the more noble metal (the ...
