Blog 18 2/7/11 Galvanic Corrosion

Galvanic corrosion is another type of corrosion, that involves 2 metals. If there are two different metals in contact with a solution, the two metals and the solution turn into a closed circuit. Because the metals are different, how many ions that they give to the solution(electrolyte) is different, so electricity will flow between them, and they will corrode. The metal that gives off more ions is the anode, and the one that does not is the cathode.
