When this happens an electric current is generated. Metals are listed in a series according to their activity. The highest in the series is the corroded end (anodic), least noble. The lowest end of the series is the protected end (cathodic), most noble.
網頁2013年8月12日 · Furthermore, based on common metal piping materials and how they react to each other, it is rarely the copper tube that fails because of galvanic corrosion. This … 網頁2013年8月12日 · Galvanic corrosion is caused by self-induced current created by electrical potential of two dissimilar metals in contact with an electrolyte. It can occur when two dissimilar metals (such as copper tube and steel pipe) are connected in the presence of an electrolyte. Fresh potable water is a weak electrolyte.
