Abstract
A new synthesis route, based on internal oxidation reactions in multiphase alloys, is proposed for the controlled production of near-surface, complex ceramic-ceramic or ceramic-metallic composite structures. Using this approa ch, a microdispersion of a complex nitride perovskite, Cr3PtN, was formed i n Cr2N or Cr(Pt) by internal nitridation of a two-phase Cr(Pt) + Cr3Pt prec ursor alloy. A framework for use of this phenomenon to synthesize island mi cro- (and potentially meso- or nano-) composite functional surface structur es is presented.
