“…The predicted microstructures range from Zone I to Zone II in the ThortonMessier structure-zone diagram. The nanohardness of TiN thin films having (2 0 0) fiber orientation is determined to be 15 GPa, that is lower than that reported for ion plated TiN films with larger grain sizes [410,411]. Chen and coworkers attributed the softening of TiN films with an average grain size of $15 nm to the grain-boundary rotation or grain-boundary sliding assisted by grain-boundary diffusion [424,426].…”

“…Titanium nitride hard coatings deposited by PVD and CVD have been implemented on an industrial scale for many years. For practical purposes, nitride hard coatings must be firmly adhered to the substrates [408][409][410][411]. However, PVD is a line-of-sight process, and the adhesion of the coating to the substrate is somewhat lower that that for CVD.…”

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respect, dislocation pile-ups cannot form, and the Hall-Petch relationship for conventional coarse-grained materials is no longer valid.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. #

“…This is typical of adhesive wear and is likely to occur when a relatively soft ball is rubbed against a much harder surface. [52] AlTiN and AlTiON coatings employed in the present work are indeed much harder than the steel ball, which softens further upon thermal exposure during the test promoting the adhesive wear conditions. Further evidence for this account previously is available from the EDS analysis of the wear track in the AlTiN and AlTiON coatings, which were found to contain as much as 1.79 and 0.94 wt pct Fe, respectively ( Figure 5).…”

Thin hard coatings provide the much needed protection for steel thixoforming tools that must resist wear at high temperatures. The wear resistance of AlTiN-and AlTiON-coated hot work tool steel was investigated at 1023 K (750°C), measured to be the cavity surface temperature shortly after the steel slurry was forced into the thixoforming die. The wear tests were repeated in exactly the same fashion with uncoated tool steel samples to identify the impact of AlTiN and AlTiON coatings on the high-temperature wear performance of X32CrMoV33 tool steel. The nature, the thickness, and the adherence of the oxide scales impact the tribological behavior. The poor adherence and limited ductility of ferrous oxides promote the failure of the oxide scale impairing the resistance to wear of the hot work tool steel at elevated temperatures. The substantial softening in the X32CrMoV33 hot work tool steel is also critical in the wear volume loss it suffers. AlTiN and AlTiON coatings, on the other hand, form a stable and protective oxide surface layer at high temperatures and therefore provide an enhanced resistance to oxidation. The latter is relatively more resistant to oxidation and is thus the better of the two coatings tested in the present work.
