Anisotropic friction properties of biomimetic Cf/ZrB2-SiC ceramic composites with bouligand structures

The anisotropic friction properties of biomimetic C f /ZrB 2 -SiC ceramic composites with fibers disposed along Bouligand structures are analyzed. First, the friction properties parallel to and vertical to the hot-pressing surfaces are analyzed for the C f /ZrB 2 -SiC ceramic composites with different carbon fiber contents. The anisotropy of friction properties of the biomimetic C f /ZrB 2 -SiC ceramic composites with Bouligand structures is analyzed based on the microstructures of wear surfaces. Second, the anisotropic friction properties of biomimetic C f /ZrB 2 -SiC ceramic composites with Bouligand structures under high speed and wet conditions are also explored. Under various working environments, the wear mechanisms including abrasive wear , adhesive wear , oxidation wear, and fatigue wear are analyzed in detail based on the microstructures of the wear surfaces. This paper provides a good reference for analyzing the anisotropic friction properties of ceramic composites with Bouligand structures.
