Fig. 6: Bright-field transmission electron microscopy images and electron energy loss spectra.

From: Humidity-dependent lubrication of highly loaded contacts by graphite and a structural transition to turbostratic carbon

Fig. 6

BF-TEM image of the regions of interests (left column) with the corresponding EELS spectra which were taken in a broad, bar-like fashion (right column). a Unworn reference layer, b graphite after sliding experiment at 50 MPa, c graphite after sliding experiment at 1 GPa. The error for the determination of the sp2 content is estimated to be 2%. For the sample at 50 MPa six ROI were taken instead of three, as the TEM analysis exhibited a more changing morphology throughout the whole layer than the other lamellae.
