“…The wear protection of TiN coatings is deteriorated accordingly [427,428]. CrN is more resistant to oxidation than TiN owing to the formation of a dense and passive oxide layer of Cr 2 O 3 that restricts further oxidation [429]. For the most part, IBAD has been utilized in fundamental scientific research rather than in the mass production sectors.…”

In recent years, near-nano (submicron) and nanostructured materials have attracted increasingly more attention from the materials community. Nanocrystalline materials are characterized by a microstructural length or grain size of up to about 100 nm. Materials having grain size of $0.1 to 0.3 mm are classified as submicron materials. Nanocrystalline materials exhibit various shapes or forms, and possess unique chemical, physical or mechanical properties. When the grain size is below a critical value ($10-20 nm), more than 50 vol.% of atoms is associated with grain boundaries or interfacial boundaries. In this respect, dislocation pile-ups cannot form, and the Hall-Petch relationship for conventional coarse-grained materials is no longer valid. Therefore, grain boundaries play a major role in the deformation of nanocrystalline materials. Nanocrystalline materials exhibit creep and super plasticity at lower temperatures than conventional micro-grained counterparts. Similarly, plastic deformation of nanocrystalline coatings is considered to be associated with grain boundary sliding assisted by grain boundary diffusion or rotation. In this review paper, current developments in fabrication, microstructure, physical and mechanical properties of nanocrystalline materials and coatings will be addressed. Particular attention is paid to the properties of transition metal nitride nanocrystalline films formed by ion beam assisted deposition process. #

“…They have become one of the most promising materials in widening application fields such as magnetics [3], electronics [4], and high temperature structure ceramics [5]. Among these nitrides, chromium nitride (CrN) is one of the most important compounds, based on its promising characteristics, such as good corrosion resistance [6,7], lower friction coefficient [8], and good oxidation resistance [9,10]. In addition, it shows a paramagnetic to antiferromagnetic transition, with a Néel temperature T N of 273-290 K [11].…”

“…[37][38][39] Recent research shows that the AE signal can give a more precise determination of the initiation of local failure compared to the coefficient of friction. 39 A burst of AE signal is often observed when a local failure happens, which can be used to detect the critical load for scratch damage.…”

Ion implantation has been widely used to improve the mechanical and tribological properties of single crystalline silicon, an essential material for the semiconductor industry. In this study, the effects of four different ion implantations, Ar, C, N, and Ne ions, on the mechanical and tribological properties of single crystal Si were investigated at both the nanoscale and the microscale. Nanoindentation and microindentation were used to measure the mechanical properties and fracture toughness of ion-implanted Si. Nano and micro scratch and wear tests were performed to study the tribological behaviors of different ion-implanted Si. The relationship between the mechanical properties and tribological behavior and the damage mechanism of scratch and wear were also discussed.
