Abstract
A contact assembly for an electrical device and a method for making such an assembly are presented. The contact assembly comprises a substrate and a contact material disposed on the substrate. The contact material comprises a composite material comprising a refractory material and a matrix material. The matrix material has a higher ductility than the refractory material. The composite material further comprises a core region and an outer region bounding the core region, the core region having a higher concentration of the refractory material than the outer region. The method applies cold spraying a blended feedstock to produce a layer that includes the composite material described above.
