在这项工作中，研究了从室温 (RT) 到 800 °C 时层状 MoAlB 陶瓷在 Al2O3 和 Inconel 718 合金 (Inc718) 上滑动的摩擦和磨损性能。研究发现 MoAlB 陶瓷的摩擦学行为受测试温度和对应温度的影响很大。从室温到 800 °C，MoAlB/Al2O3 摩擦副与 MoAlB/Inc718 摩擦副相比表现出更高的摩擦系数和磨损率。无论层状结构如何，MoAlB 陶瓷的摩擦学性能都与摩擦氧化反应引起的氧化物有关。对于 MoAlB/Al2O3 摩擦副，磨粒磨损和粘着磨损是导致不良摩擦和磨损行为的原因。然而，当MoAlB相对于Inc718滑动时，由Ni、Cr和Fe的氧化物组成的摩擦膜可以提供良好的润滑效果。
In this work, the friction and wear properties of layered MoAlB ceramics sliding against Al2O3and Inconel 718 alloy (Inc718) from room temperature (RT) to 800 °C were studied. The tribological behaviors of MoAlB ceramics are found to be greatly influenced by the test temperature and the counterpart. From RT to 800 °C, the MoAlB/Al2O3tribo-pairs exhibit a higher friction coefficient and wear rate compared with those of the MoAlB/Inc718 tribo-pairs. Irrespective of the laminate structure, the tribological properties of MoAlB ceramics are associated with the oxides that are induced by tribo-oxidation reactions. For the MoAlB/Al2O3tribo-pairs, abrasive wear and adhesive wear are responsible for the poor friction and wear behaviors. However, the tribo-film, which consists of oxides of Ni, Cr and Fe, can provide a good lubrication effect when MoAlB slides against Inc718.
