In advanced energy systems, ceramics may allow higher operating temperatures for greater efficiency. However, compressive contacts at joints with metals are required by the poor tensile behavior of ceramics. Compression at these interfaces excludes oxygen, and oxides do not form. Reactions under inert or reducing conditions (as in metal matrix composites) have been studied,(1,2) as have reactions of complex superalloys with SiC,(3) Si/SiC(4) and Si3N4.(5) The reactions were complex, dictating a phenomenological study with no treatment of their basic nature or the phase equilibria. With a model alloy containing only Ni, Cr and A1, the present experiments and analyses are an attempt to gain a more basic understanding of metal/ceramic reactions.
