“…Hardness around 20 GPa was reported by Musil et al [32] for magnetron sputtered Cr-Cu-N films with 25-at.% Cu, which is caused by the ion-bombardment (high energy)-induced grain refinement. Other studies of Musil et al [33] report that a Cu content of 1-2% leads to a maximum hardness of 50 GPa.…”

“…In the literature [30][31][32], the maximum hardness of MeCu-N nanocomposite coatings is reported to be due to the solution hardening effect and occurs at around 1-5-at% Cu. Hardness around 20 GPa was reported by Musil et al [32] for magnetron sputtered Cr-Cu-N films with 25-at.% Cu, which is caused by the ion-bombardment (high energy)-induced grain refinement.…”

“…This trend is in good agreement with the hardness measurements of the coatings discussed above in Sect. 3.3 and the solid solution hardening effect [30][31][32]. The coatings with minimum Cu content, namely 3 at.% (C3), presented the lowest wear in comparison with the substoichiometric Cr-N and the remaining Cu-Cr-N coatings.…”

Cu-Cr-N coatings with Cu contents between 3 and 65 at.%, Cu/Cr ratios in the 0.04-4.5 range and 21-27 at.% N, synthesized by twin electron-beam Physical Vapor Deposition at 450°C, were investigated and compared against substoichiometric Cr-N reference samples. The main objective of this study is to study the influence of Cu on the structure, and the subsequent effects on the mechanical properties, room (22°C) and high temperature (500 and 840°C) tribological performance of Cu-Cr-N coatings. Using X-ray photoelectron spectroscopy, glancing angle X-ray diffraction and scanning electron microscopy, in combination with nanoindentation mechanical property measurements and laboratory-controlled ball-ondisc sliding experiments, it is shown that Cu-Cr-N coatings with low Cu content (3 at.%) possess sufficient wear resistance for high-temperature demanding tribological applications. The lubricious effect of oxide formation at high temperatures is also evaluated.

“…For inorganic nanofillers, the types of nanoparticles are carbides [58], nitrites [59][60][61][73][74][75][76][77], borides [55], oxides [4,5,62,65], metallic particles [17,78], clay [4,5,35], CNT [54], and nanodiamond [56,79]. For organic nanoparticles (organic nanofiller), the most used nanoparticles were PTFE [80][81][82], PEO [83], PANi [31], or nanocellulose and cellulose nanocrystal [18,40].…”

“…By adding nanocrystal phase into the metal matrix, the volume fraction of grain boundaries might increase. Mitterer et al [153] [75,76], and CrN in Cu [77]. In these coatings, one metal may be converted into nitride in the nanocrystalline phase and the other may be transported into the growing film unreacted.…”

Incorporation of nanofillers into the organic coatings might enhance their barrier performance, by decreasing the porosity and zigzagging the diffusion path for deleterious species. Thus, the coatings containing nanofillers are expected to have significant barrier properties for corrosion protection and reduce the trend for the coating to blister or delaminate. On the other hand, high hardness could be obtained for metallic coatings by producing the hard nanocrystalline phases within a metallic matrix. This article presents a review on recent development of nanocomposite coatings, providing an overview of nanocomposite coatings in various aspects dealing with the classification, preparative method, the nanocomposite coating properties, and characterization methods. It covers potential applications in areas such as the anticorrosion, antiwear, superhydrophobic area, self-cleaning, antifouling/antibacterial area, and electronics. Finally, conclusion and future trends will be also reported.
