Title: A PROCESS FOR MAKING CERAMIC/METAL AND CERAMIC/CERAMIC LAMINATES BY OXIDATION OF A METAL PRECURSOR
Abstract:
A method of preparing a laminated ceramic. The method includes preparing a precursor having at least one noble metal element component and at least two non-noble metal elements. The precursor is exposed to a first environment to form a primary ceramic phase containing the non-noble metal elements. The precursor is next exposed to a second environment to form a second oxidized zone having a second concentration of the primary ceramic phase, the second concentration being less than the first concentration. The precursor is repeatedly exposed to each environment to form a plurality of zones with the first concentration of the primary ceramic phase separated by zones with the second concentration of the ceramic.
