Abstract
To eliminate galvanic corrosion, a housing includes a clad material. The clad material includes an interior metal disposed within an exterior metal. The exterior metal is different from the interior metal. The housing further includes a clad interface and a melt interface. The melt interface includes a layer of hardened flux disposed on a portion of the interior metal.
Claims11
A housing, comprising:
- a clad material comprising an interior metal disposed within an exterior metal, wherein the interior metal defines an internal volume and wherein the exterior metal is different from the interior metal;
- a clad interface between the interior metal and the exterior metal;
- a melt interface comprising a layer of hardened flux formed from a contiguous portion of the exterior metal;
- and
- an aperture formed through the clad material, the melt interface:
- defines a continuous boundary surface of the aperture;
- and
- extends past the clad interface and past the interior metal;
- wherein:
- the exterior metal defines a uniform grain structure portion;
- and
- the exterior metal defines a non-uniform grain structure portion at the melt interface.
9 more elements
A system configured to prevent galvanic corrosion of a housing, comprising:
- a clad structure comprising an exterior metal and an interior metal joined at a clad interface, wherein the interior metal defines an orifice at the clad interface, the orifice extends parallel with the clad interface;
- a melt interface defined by a non-uniform grain structure of the exterior metal;
- an insert disposed between the exterior metal and the interior metal within the orifice;
- an adhesive configured to bond the insert within the orifice;
- and
- an aperture formed through the clad structure and the insert, a surface of the aperture defined by the melt interface and the melt interface extends past the clad interface and past the interior metal, the aperture extends perpendicular through the clad structure, the orifice, and the clad interface.
