ELECTRICAL CONTACT COMPOSITES AND METHOD FOR PRODUCING ELECTRICAL CONTACT COMPOSITES

摘要

An electrical contact composite is described. The electrical contact composite has 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 is provided with at least one metal and/or metal alloy, the sprayed layer being arranged between the conductive coating and the contact element. 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. The sprayed layer can also be used as the electrode for the conductive coating.
