.... A nanoindentation and scratching apparatus was used for the measurements. Three different indenter and scratching tool shapes were used: 200 μm radius sphere, Vickers four-sided pyramid, and a 45° wedge with a 0.5-mm radius curved edge. During indentation, over a load range of 10 mN to 1 N, continuous load versus...
