N2 - The sliding-wear resistance of pure near fully-dense B4C is
investigated, and the wear mode/mechanisms identified, under lubrication
with water, diesel fuel, and paraffin oil. It is found that the wear is
mild in the three cases, with specific wear rates (SWRs) of 10−16–10−17 m3/N m. Nonetheless, the wear resistance of the B4C ceramic is one order of magnitude greater under oil lubrication (1016 N m/m3) than under water lubrication (1015 N m/m3),
and twice as great for the specific case of paraffin oil than diesel
fuel, attributable to the lubricant’s viscosity. It is also found that
the wear mode is always abrasion, and that the wear mechanisms are
plastic deformation and localized fracture with grain pullout. However,
in agreement with the macro-wear data, the severity of the wear damage
is lower under lubrication with paraffin oil, followed by diesel fuel,
and lastly water. Finally, microstructural considerations are discussed
with a view to enhancing the sliding-wear resistance of B4C triboceramics.
