“…We have developed carbon based (Ti, Al)(N, C)/a-C nanocomposite thin films combining nanocrystalline fcc titanium aluminium carbonitride and amorphous carbon phases in one layer structure. These coatings were synthesized for example by reactive magnetron sputtering from a TiAl 50:50 alloy target [125][126][127]. Keeping all deposition parameters fixed at constant values (i.e.…”

“…11). A five-step growth model of these coatings was suggested [127]. Disregarding that issues addressing the growth of such nanocomposite coatings require more detailed experimental and theoretical research work, one can clearly state that the specific design of such coatings by completely covering nanocrystals with an amorphous phase (which means by introducing new phase boundaries) might be a tool to optimize both hardness and toughness in a coating by generating an elastic coupling between hard nanocrystals via sp 2 -or sp 3 -hybridized carbon atoms.…”

“…The first approach is to create coatings with a limited number of advanced properties, primarily increased hardness. Nanocomposite coatings are mostly developed based on this approach [2,27,47,[89][90][91][92][93][94][95][96][97]. Recently there have been claims that nanocomposite coatings have strong potential for high-speed machining of hard to cut materials [47,98].…”

Adaptive wear-resistant coatings produced by physical vapor deposition (PVD) are a relatively new generation of coatings which are attracting attention in the development of nanostructured materials for extreme tribological applications. An excellent example of such extreme operating conditions is high performance machining of hard-to-cut materials. The adaptive characteristics of such coatings develop fully during interaction with the severe environment. Modern adaptive coatings could be regarded as hierarchical surface-engineered nanostructural materials. They exhibit dynamic hierarchy on two major structural scales: (a) nanoscale surface layers of protective tribofilms generated during friction and (b) an underlying nano/microscaled layer. The tribofilms are responsible for some critical nanoscale effects that strongly impact the wear resistance of adaptive coatings. A new direction in nanomaterial research is discussed: compositional and microstructural optimization of the dynamically regenerating nanoscaled tribofilms on the surface of the adaptive coatings during friction. In this review we demonstrate the correlation between the microstructure, physical, chemical and micromechanical properties of hard coatings in their dynamic interaction (adaptation) with environment and the involvement of complex natural processes associated with self-organization during friction. Major physical, chemical and mechanical characteristics of the adaptive coating, which play a significant role in its operating properties, such as enhanced mass transfer, and the ability of the layer to provide dissipation and accumulation of frictional energy during operation are presented as well. Strategies for adaptive nanostructural coating Topical Review design that enhance beneficial natural processes are outlined. The coatings exhibit emergent behavior during operation when their improved features work as a whole. In this way, as higher-ordered systems, they achieve multifunctionality and high wear resistance under extreme tribological conditions.

“…Under optimum conditions nanocomposite coatings with a structure of a coexisting metastable hard, nanocrystalline fcc TiAlNC phase and an amorphous carbon phase (a-C) have been deposited. Stueber et al [5] considers different aspects of the synthesis, deposition methods, growth, microstructural evolution and properties of multifunctional, wear resistant and lubricious nanocomposite coatings. These coatings have a special nano-architecture and are composed of the different carbon-based nanocomposite layers.…”

Abstract. The aim of this work was to investigate mechanical and cutting properties, as well as the nature of wear and failure of carbide cutting tools with modifying coatings of two types: nanostructured multi-layered coating Zr-ZrN-(ZrCrAl)N, applied through the use of the technology of filtered cathodic vacuum arc deposition, and multi-layered nano-structured and gradient coating Ti-(TiAl)N-(TiAl)N, applied through the use of the technology of LARC ® (Lateral Rotating Cathodes). It is found out that the both types of coatings under test significantly improve tool life of a carbide cutting tool. The studies of mechanisms of wear and failure of carbide tools with coatings under test, conducted at macro and micro levels, have identified their major differences and revealed their most preferable field of application. The carbide tools, equipped with cutting inserts with the nano-structured multi-layered coating under study, provided a significant increase in cutting properties (tool life) of the tool in comparison with the uncoated carbide tool and in comparison with the reference carbide tool with TiN coating. The tool with the coating Ti-(TiAl)N-(TiAl)N under study demonstrated the increased wear resistance during 30-35 min of cutting, and then, the process of coating failure and tool wear was sharply intensified. For the tool with coating Zr-ZrN-(ZrCrAl)N, the tests revealed more evenly-balanced wear during the whole operating time between failures. It should be noted that NMCC Zr-ZrN-(ZrCrAl)N are substantially thinner, and that fact predetermines their better resistance to failure because of crack formation, and the technology of its generation is more cost-effective.
