摘要：
Al2O3/Ni laminar ceramic composite was fabricated by aqueous tape casting with close control of the thickness of Al2O3 and nickel layers. Owing to a high flexibility and strength, green tapes of Al2O3 and Ni could be laminated easily at room temperature. The compact, defect free interfacial structures of Al2O3/Ni laminar composites sintered by hot-pressing (HP) at 1400 degrees C were investigated by X-ray diffraction (XRD) and energy dispersive X-ray analysis (EDX). It is shown that the diffusion of Al and Ni caused a progressive boundary between Al2O3 and Ni layers. The Al2O3/Ni laminar composite was mostly composed of Al2O3 and Ni phases, together with a small amount of MgAl2O4, Al4Ni3 and NiAl10O16 phases. (C) 2005 Elsevier Ltd and Techna Group S.r.l.
