An assembly for limiting corrosion between a first member made of a first material and a second member made of a second material, different from the first material, includes a plurality of cylindrical dimples defined in the first member. The cylindrical dimples are formed as a one-piece structure with the first member. The cylindrical dimples and the second member interact to define a plurality of galvanic contact zones. An electrocoat covers substantially all of the first member and the second member, but does not cover the galvanic contact zones. Therefore, the galvanic contact zones are not in contact with the electrocoat and are sealed to prevent contact with an electrolyte. A method of assembling a first member to a second member, to limit corrosion therebetween, is also provided.
An assembly for limiting corrosion between a first member made of a first material and a second member made of a second material different from the first material, the assembly comprising:
A method of assembling a first member to a second member, comprising:
