Ceramic-metal composites, or cermets, combine a high hardness ceramic phase with a ductile metallic ‘binder’, and are widely used in severe wear and corrosion environments. The proposed research programme involves continued development of TiC and Ti(C,N) based cermets, using high ductility Ni3Al-based binder alloys. Two novel cermet ‘architectures’ are proposed in this work: (i) hierarchically structured materials, with constituent phases on nano- to macro-length scales, for high performance wear/corrosion applications, and (ii) lightweight, controlled pore morphology materials, for high energy impact absorption.

陶瓷-金属复合材料或金属陶瓷，联合收割机将高硬度陶瓷相与延展性金属“粘合剂”结合，并且广泛用于严重磨损和腐蚀环境中。拟议的研究计划涉及继续发展TiC和Ti（C，N）基金属陶瓷，使用高延展性Ni 3Al基粘结剂合金。在这项工作中提出了两种新的金属陶瓷“架构”：（i）层次结构的材料，与纳米到宏观长度尺度上的组成相，用于高性能磨损/腐蚀应用，和（ii）轻质，可控的孔形态材料，用于高能量冲击吸收。
