Abstract

Abstract Translated from German 57 Bei einem Metall-Keramik-Verbundelement aus Keramiksubstrat (4), eutektischer Zwischenschicht (2) und Metallschicht (1) werden die thermischen Eigenschaften durch Einsatz einer Nitridkeramik verbessert. Die Haftfestigkeit der Metallschicht (1) auf der Nitridkeramik wird durch eine Oxyd-Zwischenschicht (3) erreicht, die durch thermische Oxydation in einer sauerstoffhaltigen Atmosphäre auf die Nitridkeramik augebracht wird. 57 In the case of a metal-ceramic composite element composed of ceramic substrate (4), eutectic intermediate layer (2) and metal layer (1), the thermal properties are improved by using a nitride ceramic. The adhesive strength of the metal layer (1) on the nitride ceramic is achieved by an intermediate oxide layer (3), which is applied to the nitride ceramic by thermal oxidation in an oxygen-containing atmosphere.
