Abstract: To eliminate galvanic corrosion, a housing includes a clad. The clad includes an interior metal disposed within an exterior metal and a clad interface. The exterior metal includes a lower electrical conductivity potential than the interior metal. An aperture can extend through the exterior metal and the clad interface and an actuator or a plug can be disposed within the aperture. The housing further includes a corrosion resistant coating disposed on a portion of the interior metal at the clad interface. The corrosion resistant coating can include a thickness between about 2 μm and about 10 μm.
