Superlubricity of hydrogenated diamond-like carbon (H-DLC) film in vacuum was achieved against four different friction pairs (ZrO₂, Al₂O₃, Si₃N₄ and SiC) due to the formation of graphene and nanoscrolls in transfer layer as well as the graphitization of contacted substrate; however, the durability of superlubricity was significantly diverse. The Al₂O₃/H-DLC pair presents much longer superlubricity lifetime than other three tribology systems. Combining with the experimental characterizations and the first principles calculation results, the synergistic effects from mechanical action and interfacial adhesion interaction between two sliding surfaces were found to mainly respond to the superlubricity failure of H-DLC films. High mechanical action or/and strong interfacial adhesion interaction facilitated the wear of counterface or H-DLC substrate, either of which would largely weaken the durability of superlubricity. Through with the similar mechanical action compared to the Si₃N₄/H-DLC interface, the Al₂O₃/H-DLC interface was capable of durable superlubricity since the much weaker interfacial adhesion interaction helps maintain the stable transfer layer on the ball surface and form smoothly graphitized substrate surface in the contacted region.

由于在传输层中形成了石墨烯和纳米滚动体，在四个不同的摩擦对（ZrO ₂，Al ₂ O ₃，Si ₃ N ₄和SiC）上获得了氢化的类金刚石碳（H-DLC）薄膜在真空中的超润滑性。以及接触基材的石墨化；但是，超润滑性的持久性差异很大。铝₂ O ₃/ H-DLC对具有比其他三种摩擦学系统更长的超润滑寿命。结合实验表征和第一性原理计算结果，发现机械作用和两个滑动表面之间的界面粘附相互作用的协同作用主要是对H-DLC薄膜的超润滑失效的响应。较高的机械作用力和/或较强的界面粘合力促进了对接面或H-DLC基材的磨损，这两种情况都将大大削弱超润滑性的耐久性。与Si ₃ N ₄ / H-DLC界面相比，Al ₂ O ₃具有类似的机械作用/ H-DLC界面具有持久的超润滑性，因为较弱的界面粘合力有助于保持球形表面上的稳定转移层，并在接触区域内形成平滑的石墨化基材表面。
