Galvanic corrosion is an electrochemical action of two dissimilar metals in the presence of an electrolyte and an electron conductive path (Figure 15.9).A potential difference usually exists when two dissimilar metals are in contact. In such case, corrosion of less resistant metal is increased while corrosion for more resistant metal is reduced; whereas, more active metal acts …
