PROCESS FOR MAKING COMPLEX-SHAPED CERAMIC-METAL COMPOSITE ARTICLES

摘要

The invention is a process for the preparation of a solid yet complex-shaped ceramic-metal composite article, comprising: a) forming a shaped metal body; b) contacting the shaped metal body with ceramic material to form a layer of the ceramic material on one or more suface(s) of the shaped metal body; and c) infiltrating the ceramic material with the metal of the shaped metal body such that a solid, complex-shaped ceramic-metal composite article comprising one or more metal phases and one or more ceramic phases is formed, wherein the article has substantially the net shape of the shaped metal body.
