Abstract: Multimodal cermet compositions comprise a multimodal grit distribution of the ceramic phase. The compositions include a) a ceramic phase and b) a metal binder phase, wherein the ceramic phase is a metal boride with a multimodal distribution of particles, wherein a metal is a Group IV, V, or Vl metal, and wherein the metal binder phase comprises (i) Fe, Ni, Co or Mn and (ii) Cr, Al, Si, Y or Ti. The method of making multimodal boride cermets includes mixing multimodal ceramic phase particles, pressing the particle, liquid phase sintering of the compresses mixture at elevated temperatures, and finally cooling the multimodal cermet composition. Advantages of the multimodal cermets are high packing density, high fracture toughness and improved erosion resistance at up to 100 deg C. The multimodal cermets are suitable in high temperature erosion/corrosion chemical and petroleum environments.
