Abstract

A new kind of multi-phase ceramic composite comprising of a SiC matrix reinforced with Si₃N₄ and BN was prepared by in-situ formation during nitridation of Si metal and B₂O₃. Al₂O₃ was used as a sintering additive as well as to improve oxidation and corrosion resistance. XRD and SEM techniques were effectively utilized to confirm phases and analyse the evolutionary changes in microstructure. Dry wear tests were conducted to evaluate the composite’s wear resistance. It was discovered that the SiC-Si₃N₄–BN–Al₂O₃ composite possessed exceptional properties, such as high hardness, high abrasive wear resistance, and low coefficient of friction. The examination of surface topography using atomic force microscopy indicates that the composites exhibit improved smoothness and enhanced capacity for load bearing. These characteristics make the composite material highly promising for diverse tribological applications. Furthermore, the strengthening and wear mechanisms of this composite were analysed and discussed in this paper.

期刊介绍： Tribology is the science of rubbing surfaces and contributes to every facet of our everyday life, from live cell friction to engine lubrication and seismology. As such tribology is truly multidisciplinary and this extraordinary breadth of scientific interest is reflected in the scope of Tribology International. Tribology International seeks to publish original research papers of the highest scientific quality to provide an archival resource for scientists from all backgrounds. Written contributions are invited reporting experimental and modelling studies both in established areas of tribology and emerging fields. Scientific topics include the physics or chemistry of tribo-surfaces, bio-tribology, surface engineering and materials, contact mechanics, nano-tribology, lubricants and hydrodynamic lubrication.
