“…The TiAlNbN/AlCrN coating exhibited a denser structure than the TiAlNbN coating resulted from the effect of the introduction of AlCrN and multilayer interruption, which inhibited the coalescence of columnar growth. Similar results of dense columnar structures can be observed in the AlCrN/AlTiSiN multilayer coatings with periodic thickness of ~11.6 nm [ 31 ]. The dense and multilayered structure had the effect of combining the concept of alloying of AlTiN by adding Si and the application of a multilayer architecture on the oxidation resistance and improved the mechanical properties.…”

In tribological applications, the degradation of alloy nitride coatings is an issue of increasing concern. The drawbacks of monolayer hard coatings can be overcome using a multilayer coating system. In this study, single-layer TiAlNbN and multilayer TiAlNbN/AlCrN coatings with AlCrN layer addition into TiAlNbN were prepared by cathodic arc evaporation (CAE). The multilayer TiAlNbN/AlCrN showed B1 NaCl structure, and the columnar structure continued from the bottom interlayer of CrN to the top multilayers without interruption. After AlCrN addition, the TiAlNbN/AlCrN coating consisted of TiAlNbN and AlCrN multilayers with a periodic thickness of 13.2 nm. The layer thicknesses of the TiAlNbN and AlCrN were 7 nm and 6.2 nm, respectively. The template growth of the TiAlNbN and AlCrN sublayers stabilized the cubic phases. The introduction of bottom CrN and the TiAlNbN/CrN transition layers possessed com-position-gradient that improved the adhesion strength of the coatings. The hardness of the deposited TiAlNbN was 30.2 ± 1.3 GPa. The TiAlNbN/AlCrN had higher hardness of 31.7 ± 3.5 GPa and improved tribological performance (wear rate = 8.2 ± 0.6 × 10−7 mm3/Nm) than those of TiAlNbN, which were because the multilayer architecture with AlCrN addition effectively resisted abrasion wear.

“…However, it is also important to understand that the performance of the tools is not only governed by the coating; the substrate also plays a relevant role in the deformation and fracture of the surface. Currently, most of the literature on mechanical performance of the quaternary coatings and multilayers only concentrates on the coating itself, ignoring the synergic effect with the substrate [ 25 , 26 , 27 ]. The tribological performance, oxidation resistance, and thermal stability of quaternary coating have been studied in several prior studies [ 28 , 29 , 30 , 31 , 32 ]; however, there is scarce information on the evolution of mechanical properties with thermal treatments.…”

The objective of this study was to explore the mechanical properties of AlCrSiN and AlTiSiN coatings deposited on Inconel and steel substrates after thermal treatments of 500 °C and 800 °C. Nanoindentation was used to measure the hardness and elastic modulus of the coatings, and microindentation was used for observing the contact damage with Hertzian contact loadings. Microscratch and Mercedes tests were used to evaluate the adhesive strength between coating and substrate with both progressive and static loads, respectively. The surface damage was inspected by optical microscopy and scanning electron microscopy (SEM). Focus ion beams (FIB) were used to mill the cross-sections in order to detect the extent and mode of failure. The results show that AlCrSiN coatings and Inconel substrates exhibit better mechanical performance, even after thermal treatments.

“…It is evident that the higher H IT /E IT parameter exhibits a multilayer architecture of all analyzed coatings. Conversely, H IT 3 /E IT 2 ratio is associated with the resistance of coatings against plastic deformation [30,31]. However, the multilayer structure of WN x /TiSiN coating shows the minimal value of that parameter (0.181 GPa).…”

“…Moreover, dislocation motion is hindered by grain boundaries inside the WN x /TiSiN multilayer, which leads to dislocation accumulation. Then, this process can improve the yield strength resulting in the enhanced hardness of the multilayer [30]. Figure 4 shows the H IT /E IT and H IT 3 /E IT 2 ratios of WN x , TiSiN, and WN x /TiSiN coatings.…”

The present work deals with the comparison of selected properties of WNx/TiSiN multilayer and respective WNx and TiSiN monolithic coatings that were deposited at the same parameters. The effect of the multilayer architecture on the structure and mechanical properties of WNx/TiSiN multilayer was studied in detail. The multilayers and monolayers were fabricated on high-speed steel substrates by unbalanced direct magnetron sputtering from W (purity 99.95 %) and Ti80Si20 (purity 99.50 %) targets. The chemical composition and the cross-sectional morphology of multilayer and single-layer coatings were characterized by scanning electron microscopy (SEM) equipped with wave-dispersive X-ray spectroscopy (WDS). The structure was analyzed by X-ray diffraction (XRD). The hardness and Young’s modulus of multilayer and coatings were investigated using the nanoindentation method. Results showed that the WNx/TiSiN multilayer, possessing cubic W and TiN phases and a dense layered microstructure, showed slightly improved hardness (28.5 ± 3.5 GPa) and HIT/EIT parameter (0.087), as compared with the WNx and TiSiN coatings. It has been shown that the design of multilayered structure of WNx/TiSiN coating is a promising way to tailor the microstructure and properties of the hard coatings.
