Tribological Behaviors of Dense Gelcasting Nanocomposites
Keyword(s):
Gelcasting/pressure less sintered Al2O3/SiC nanocomposites has a low sinterability. Also, mechanical and wear properties of these nanocomposites was degraded. Wear mechanism of low sinterability gelcasting nanocomposites was dominated by fracture mode of surface during wear tests. In this study, gelcasting processing and followed plressureless (PL) and hot isostatic pressing (HIP) sintering was attempted to fabricate dense Al2O3/SiC nanocomposites. Wear behaviors of high densities gelcasting nanocomposites were investigated under the identical wear test condition. The comparative specimen was used to hot pressed nanocomposites. Wear rates of dense gelcasting nanocomposites were related to closely initial friction coefficient.
