Abstract

The invention relates to the protection of welds and/or connections from corrosion of materials, for example materials in an electrolyte solution. In one example, a Feedthrough pin made from titanium is welded to an aluminum mandrel. At a minimum, the weld joint between the dissimilar metals can be coated with a nonconductive coating. Examples of nonconductive coatings include PVDF and other polymers, ceramics, and waxes. The nonconductive coating could be applied by spraying, roll-coating, ion deposition, sputtering, painting, pad printing, evaporative coating techniques (with solvent or other material removal by evaporation), or other methods of applying a conformal coating over a substrate.
