The origin of superhardness of nanocomposite coatings: analysis of nanoindentation and scratch tests

Nanocomposite coatings characterized by superhardness exhibit unique microstructures and deformation mechanisms at the nanometre scale. Based on the studies of nano-indentation size effect, we show that dislocation-based deformation is gradually replaced by grain-boundary mediated deformation as the...
