Abstract

Distinction between superhard coatings obtained by energetic ion bombardment during their deposition and superhard nanocomposites whose superhardness and high thermal and oxidation stability originates from a stable nanostructure is described together with the properties of the latter materials. The reasons for the poor reproducibility of our data as reported by some authors may be either an incorrect choice of a too low nitrogen pressure or temperature during the deposition or built-in impurities, or a combination of those.
