"The main aim of the project is to prepare a new generation of nanocomposite coatings, which are simultaneously hard and tough and exhibit an enhanced resistance to cracking, and to understand the physical mechanisms of their formation. Highly elastic hard coatings with the hardness H and the lowest Young\u2019s modulus E, satisfying the ratio H/E>0.1, being resistant to cracking will be developed. Correlations between H, E, the elastic recovery We, elemental and phase composition of the coating, its properties and resistance to cracking will be found. Nanocomposites composed of oxide, nitride phases and their combinations will be investigated. Formation of oxide nanocomposites with very high deposition rates >1 \u00B5m/min will be mastered using a combined sputtering and evaporation process. Interlayers composed of many nano-bilayers, evolving a great amount of the heat in self-heating high temperature process induced by an intense heat pulse, will be developed for a new joining of the coating with the substrate."@en .
