Another method used to prevent galvanic corrosion is by electrically insulating the two metals from each other by using non-conductive materials such as plastics because if the two metals are not in electrical contact, no corrosion will occur. Not, however, on sterling silver. Unlike steel, aluminum resists corrosion by moisture and air when exposed to the elements, but salt spray and road salts can cause a condition caused oxidation, which discolors the aluminum surface. The process is called anodizing because the part to be treated forms the anode electrode of an electrolytic cell.Anodizing increases resistance to corrosion and wear, and provides better adhesion for paint primers and glues than bare metal does. One metal (the cathode) is protected, whilst the other (the anode) is corroded. Used in one of the world's tallest buildings - the Willis Tower in Chicago, Illinois.
