摘要: Properties of hard nanocomposite coatings, especially hardness, can be explained by their nanostructure. Hardness maxima are found for different nanocrystalline/amorphous materials deposited techniques at typically 20% the amorphous phase. A zone model is proposed which correlates hardness to relative phase content. The coatings peaks common minimum grain size crystalline and separation. For an adequate description performance a coating, thermal stability, oxidation behavior frictional should included in addition hardness. In friction situation involving least two partners, overall system determined many-body interactions. While stability properties as inherent material directly linked nanostructure coating cannot generalized independent conditions.
