Abstract
Silicon nitride-based nanocomposites with different amount (0, 1, 2 wt%) of multiwall carbon nanotubes (MWCNT) have been prepared by hot isostatic pressing. Tribological tests were carried out at room temperature, in dry sliding condition using pin-on-disc test apparatus, applying different normal loads and sliding speeds. Wear phenomena was analysed by scanning electron microscopic investigations of the wear tracks. Based on the controlling wear mechanisms and wear types two-dimensional wear mechanisms maps were created for all composition of the investigated ceramic nanocomposites.
