ABSTRACT:
Galvanically incompatible materials are isolated from each other to prevent galvanic corrosion while providing for electrical conductivity therebetween. A two-sided shim is interposed between the galvanically incompatible materials and each side of the shim is galvanically compatible and placed in contact with one of the galvanically incompatible materials. The shim itself is sealed against moisture to prevent galvanic corrosion in a central contact area between the two sides. Holes through the shim to permit the insertion of fasteners therethrough must similarly be sealed.
