US Patent 7804172 Electrical connections made with dissimilar metals

Electrical connections between different materials. An electrical connection system includes electrical components and an electrical connection between the electrical components. The electrical connection includes a functionally graded material. A method of making an electrical connection between different materials includes the steps of: providing an electrical component which includes a material; providing another electrical component which includes another material; and electrically connecting a functionally graded material between the electrical components. An electrical connection system includes an electrical component and a functionally graded material electrically connected to the electrical component. The functionally graded material provides a gradual transition between at least two dissimilar materials.
