Large values of the H/E ratio up to 0.09 are observed for grain sizes in the nanometer range along with a hardness above 10 GPa and Young's modulus below 230 GPa.

The friction coefficient of such films against diamond tip was in the range 0.08-0.15, similarly to metallic glass surfaces. (C) 2011 Elsevier Ltd. All rights reserved.
