“…showed that the introduction of the ZrNbN barrier layer between the TiAlN and CrN layers led to an increase of its thermal stability [15]. This is because TiAlN and CrN compounds dissolve in one another; therefore, the ZrNbN layer creates a barrier to their mutual solvency.…”

“…Coatings may have multiple physical purposes; on the one hand, the coating in spite of its tiny thickness (few micrometers), improves substrate properties such as surface hardness, physical-chemical passivity towards workpiece material, antifriction and thermal insulation. On the other hand, during the cutting process, the coating transforms the contact characteristics such as adhesion interaction, friction and inter-diffusion between workpiece and tool materials [1,3,8,[13][14][15][16]. The reduction of these characteristics allows lowering stresses (normal and shear), frictional heat capacity and thermal stresses acting at the contact areas of tool.…”

“…With this approach the hardness of the coatings can reach 45-50 GPa [10][11][12][13][14]. The coatings retain an appreciably high viscosity because they dissipate the brittle fracture energy at the inter-grain and interlayer boundaries [15]. The high hardness and resistance to plastic deformation of these type nanolayered composite coatings are determined by the increased strength of their adhesion to various substrates compared to that of coatings without a multilayered structure [16].…”

In coated tools, the grain boundaries and coating layers are areas of intense energy dissipation, which hardens the coating material by increasing its toughness and its resistance to the formation and development of cracks. An increase in the efficiency of the coatings was achieved by applying nano-dispersed multilayer composite structure. This paper proposes using nano-scale multilayer composite coating based on TiN-CrN compound to improve thermal stability, where, barrier layers based on ZrNbN have been introduced. The ZrNbN barrier does not interact with TiN and CrN at temperatures around 1000°C. The influence of process parameters of the filtered cathodic vacuum arc deposition on the composition, structure and properties of the coatings based on variation of TiAlN-ZrNbN-CrN was analyzed. The results presented here show that the hardness of the developed coatings was as high as 38 GPa. Subsequently, the carbide tools used in this study with the new coatings had an increased lifetime of 1.5-2.0 times compared to tools with commercial coatings. The coated tools were tested in turning and milling of steels, nickel and titanium alloys.

“…Transition nitride multilayer thin films were deposited with ultrahigh vacuum (UHV) direct current (dc) magnetron sputtering in a Leybold L400Sp system on h100i-oriented silicon substrates at a substrate temperature of $70 C. 50,51 Three different types of multilayer combinations, namely TiN/NbN, NbN/CrN, and TiN/CrN 49 and corresponding single-layer reference coatings of TiN, NbN, and CrN were deposited (see Table I). 45,49 Hardness and Young's modulus values of the coatings were obtained by nanoindentation using a TriboIndenter (Hysitron, Inc., Minneapolis, MN) equipped with a Berkovich-shape diamond tip.…”

Systematic studies of the deformation mechanisms of multilayer transition metal nitride coatings TiN/CrN, TiN/NbN, and NbN/CrN, and corresponding reference coatings of TiN, NbN, and CrN deposited by a direct current (dc) magnetron sputtering process onto silicon h100i have been performed. Mechanical characterization was conducted using a combination of microindentation and nanoindentation in the load range 30 to 150 mN and 0.5 to 3.5 mN, respectively. For both load ranges, scanning electron microscopy (SEM) in situ indentation was used to observe the indentation process including any pileup, sink-in, and fracture mechanisms specific to each coating. The coatings' microstructure, both before and after indentation, was analyzed using transmission electron microscopy (TEM). It was possible to both correlate the indentation load-displacement response to surface roughness effects and fracture modes (substrate and film cracking) and observe deformation mechanisms within the coatings.

“…A similar behavior was reported by Marulanda et al [34] where an increase in wear volume for coatings with a bimodal period of 20 nm was found. The behavior was associated to the weak interface bonding strength and residual stresses present in the coatings [35]. Therefore, it is supposed that a deterioration of the mechanical properties of Cr0.25/CrN0.25 coating can be related to the 96 layers which are a part of the coating architecture.…”

The wear of metallic components used in gas and steam turbines due to erosive sand particles leads to a tremendous decrease in their lifetime. This wear can be reduced by the use of suitable erosion resistant coatings resulting in lower maintenance costs. In this context, multilayer Cr/CrN PVD coatings using an industrial coater were designed and applied on Inconel 718, a material which finds its application in gas turbines. A variation in the bimodal period has been induced in order to achieve an optimal coating architecture providing optimum properties needed for the erosion resistant coatings. The coating was deposited using a single Crtarget with an induction of N 2 during the nitriding phase at a temperature of 480-500 ∘ C and the coating thickness of 24-26 m was kept constant throughout. The erosion tests were conducted at angles of 30 ∘ , 60 ∘ , and 90 ∘ . The sand used for the test is an irregular shaped SiO 2 . The erosion tests were followed by a detailed microscopic examination of the eroded coating structure in combination with nanoindentation and scratch tests.
