摘要: Abstract To prepare epoxy-based composites with low frictional coefficient and high wear resistance, nanometer silicon nitride particles were added. Dry sliding tests indicate that the composite materials exhibit significantly improved tribological performance mechanical properties at rather filler content (typically less than 1 vol.%). Unlike severe observed in unfilled epoxy dominated by fatigue-delamination mechanism, mode of nano-Si 3 N 4 is characterized mild polishing. It believed strong interfacial adhesion between Si nanoparticles matrix, reduced damping ability enhanced resistance to thermal distortion composites, tribochemical reactions involving account for rate composites.
