Nanocrystalline diamond (NCD) offers great potential for many micro-mechanical systems, particularly where low friction, reliability and mechanical integrity are of great importance. The reduction of grain size in NCD films to several nanometers is, however, accompanied by a significant change in morphological, chemical, mechanical and especially tribological properties. The evaluation of the friction and wear behavior, including the running-in-period and steady-state friction is necessary before designing NCD-coated micro-mechanical components for which reliability, wear resistance and long lifetime are crucial issues. This work shows a correlation of microstructure and tribological properties in nanocrystalline diamond films.
