Understanding Mechanism of Super-Lubrication Driven by Graphite/Fullerene Composite using in-situ TEM

利用透射电子显微镜（TEM）对类金刚石（DLC）超润滑机理进行了研究。在我们以前的工作中，纳米尺度的轴承形成在DLC-DLC界面与50 nm的凹凸在循环摩擦测试。纳米尺度的轴承也形成在DLC-DLC界面只有几个纳米的粗糙。因此，DLC超润滑机制可以通过DLC纳米球在界面处的旋转来驱动。然而，我们不能想象石墨/富勒烯复合材料，我们应该了解它的机制，在最初的建议，使用我们的TEM装置

We revealed a mechanism of super-lubrication of diamond-like carbon (DLC) using in-situ transmission electron microscopy (TEM). In our previous work, nano-scaled bearings formed at a DLC-DLC interface with 50 nm asperities during a cyclic friction test. The nano-scaled bearings also formed at a DLC-DLC interface just with a few nm asperities. With this, the mechanism of DLC super-lubrication could be driven by the rotation of DLC nanoballs at the interface. However, we could not visualize a graphite/fullerene composite, which we supposed to understand its mechanism in theinitial proposal, using our TEM setup
