From the five, 3 were pure materials: BHA, CSHA and Al2O3.
Fig. 1e shows the conductivity [ln(S/cm)] of the samples in which the composite materials exhibit a better insulating behaviour than that of the pure materials.
Therefore it is observed that the composite materials exhibit a much better insulating behaviour than the pure materials.
While the electrical values of the composite materials started at a lower value and like the pure materials show a logarithmic decrease with increase of frequency.
The composite materials exhibit better conductivity than pure materials.

From this result, it can be understood that the materials removal in comparatively large volume was happened by the increase in the activation energy with heating.
From these results, it can be also understood that the materials removal and deformation will be activate by heating.
Conclusion In order to clarify the influence of the grinding heat on the materials removal process, nano-scratching experiments in vacuum by an atomic force microscope (AFM) and molecular dynamics simulations under room and high temperature, respectively.
