| Summary: | Title screen The study investigated the effect of hexagonal boron nitride (h-BN) content on fracture toughness and abrasive wear resistance of ZrB2–TiB2–SiC composites. Four compositions of ceramic composites were prepared from powder mixtures by pressure sintering at 1850 °C. In all the composites, the TiB2:ZrB2:SiC ratio was maintained as 16:69:15. The h-BN content in the ceramic composites was 3, 5, and 7 vol %. Sintering of the ceramic composites yielded the formation of (ZrTi)B2 solid solution, with the ratio of ZrB2 and TiB2 components remaining constant, irrespective of the h-BN content in the composites. The addition of hexagonal boron nitride into the (ZrTi)B2–SiC matrix was found to enhance fracture toughness through two mechanisms: crack propagation inhibition under residual compressive stresses and the Cook-Gordon mechanism. It was revealed that (ZrTi)B2–SiC–h-BN composites are more susceptible to abrasive wear when compared to (ZrTi)B2–SiC composites. Abrasive wear of (ZrTi)B2–SiC–h-BN composites occurs due to the formation of subsurface microcracks, their propagation to relatively weak interface between low-modulus h-BN inclusions and high-modulus (ZrTi)B2–SiC matrix, and subsequent separation of h-BN. The study showed that a greater number of subsurface microcracks are formed on the wear surface of (ZrTi)B2–SiC–h-BN composites compared to (ZrTi)B2–SiC composites. Furthermore, it was determined that composites containing 3 vol % h-BN exhibit the highest residual bending strength after abrasion Текстовый файл AM_Agreement |
