Název v původním jazyce

Physical and mechanical properties of hard nanocomposite films prepared by reactive magnetron sputtering

Popis výsledku v původním jazyce

Nanocomposite coatings represent a new generation of materials, which exhibit new unique properties. The article reviews the present state of the art in magnetron sputtering of hard and superhard nanocomposite coatings and reports on recent advances in this field. At first, the information of nanocrystalline and nanocomposite films and the microstructure of single-phase and two-phase films are described in detail. Next, an attention is devoted to the enhanced hardness. It is shown that the hardness of the nanocomposite film can be more than two times higher than the hardness of its hardest component, there are two groups of hard and superhard nanocomposites: nc-MeN/hard hard phase and nc-MeN/soft phase, H correlates well with the film structure and there are four possible origins of the enhanced hardness: dislocation-dominated plastic deformation, cohesive forces between atoms, nanostructure of materials and macrostress generated by ion bombardment.
