ELECTRICAL CONTACT COMPOSITES AND METHOD FOR PRODUCING ELECTRICAL CONTACT COMPOSITES.

摘要

The invention relates to an electrical contact composite, comprising a substrate and an electrically conductive coating applied to the substrate, which coating is connected to an electrode. A metal contact element is connected to the electrode, which contact element is used to connect the conductive coating to a current/voltage source. Furthermore, at least one sprayed layer produced by means of a thermal spraying method, in particular gas dynamic cold spray, and comprising at least one metal and/or metal alloy is provided, which sprayed layer is arranged between the conductive coating and the contact element, wherein the sprayed layer has a coefficient of thermal expansion that is between the coefficients of thermal expansion of the carrier and of the contact element. In one variant, the sprayed layer is used as the electrode for the conductive coating.
