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.

研究了在水，柴油和石蜡油的润滑下，纯近乎全密实的B ₄ C的耐滑动磨损性，并确定了磨损模式/机理。发现这三种情况下的磨损是轻微的，比磨损率（SWR）为10 ^-16 –10 ^-17  m ³ / N m。尽管如此，油润滑（10 ¹⁶  N m / m ³）下的B ₄ C陶瓷的耐磨性比水润滑（10 ¹⁵  N m / m ^{3）大一个数量级。}），并且由于润滑剂的粘度，对于石蜡油的具体情况要比柴油大两倍。还发现磨损模式始终是磨损，并且磨损机制是塑性变形和带有晶粒拉出的局部断裂。然而，与宏观磨损数据一致，在使用石蜡油，其次是柴油和最后是水的润滑条件下，磨损损坏的严重程度较低。最后，讨论了微观结构方面的考虑，以增强B ₄ C摩擦陶瓷的抗滑动磨损性。
