... Protection , Volume 13A of the ASM Handbook , 2003. Although sometimes considered a form of corrosion, galvanic corrosion is more accurately considered a type of corrosion mechanism, because galvanic action is the basis for, or can accelerate the effects of, other forms of corrosion. Uniform attack...

...), certain background elements may accelerate corrosion. Increasing the alloy iron and sulfur content, for example, increases corrosion rates when corrosion rates exceed ∼0.10 mm/yr (3.9 mils/yr) ( Ref 11 , 12 ). Thus, minor variations in alloy chemistry may be of concern only under conditions in which the...
