Abstract:
1. A method of fabricating a metal and ceramic layered material system, comprising: selecting a metal material and a ceramic material with respective coefficients of thermal expansion that are within 15% of each other throughout an operating temperature range plus a co-sintering temperature range; forming a substrate from a powder of the metal material; disposing a layer on the substrate, wherein the layer comprises a powder of the ceramic material containing at least 2% by volume of ceramic nano-particles having an average diameter of less than 100 nm; co-sintering the substrate and the layer within the co-sintering temperature range to a final density of the substrate of at least 97% theoretical density; and selecting the metal material, the ceramic material, and the percentage of ceramic nano-particles such that the co-sintering produces respective shrinkage amounts of the layer and the substrate that are within 1.0% of each other throughout the co-sintering thereof.
