Arrangement for preventing galvanic corrosion and method for assembling the same

摘要

An arrangement for restricting corrosion between a first element made of a first material and a second element made of a second material that is different from the first material comprises a plurality of cylindrical recesses defined in the first element. The cylindrical recesses are formed as a one-piece structure with the first element. The cylindrical recesses and the second element interact to define a plurality of galvanic contact zones. An electrodeposition coating covers the first element and the second element essentially completely, but does not cover the galvanic contact zones. Therefore, the galvanic contact zones are not in contact with the electrocoating and are sealed to prevent contact with an electrolyte. A method of assembling a first member with a second member to limit corrosion therebetween is also provided.
