| Research Abstract |
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
