The anisotropic removal behavior of single crystal calcium fluoride (CaF2) severely restricts the improvement of surface quality in ultra-precision machining. In this study, the anisotropic mechanical removal of CaF2 material was investigated quantitatively along various crystal orientations on CaF2(111), (110), and (001) surfaces by a conical diamond tip. With the increase of load, the wear of CaF...
The present study evaluated the wear behavior of human root canal dentin and the lubricating effect of EDTA pastes using nano-scratch tests in vitro. The human root canal wall specimens were tested under a constant load of 80mN and the lubricating effect of different concentrations of EDTA pastes were analyzed. EDTA lubrication strengthened wear effect on the root canal dentin. The application of...
