“…Recently, CrN/MoN coating has been deposited on 12X18H9T stainless steel using Vacuum arc evaporation method by Pogrebnjak et al [109]. Multilayers of chromium and molybdenum are believed to induce the high value of hardness [110][111][112][113][114][115][116], and the observation on the well-defined multilayer structure of this study confirms it. The coating exerts high hardness value at 42.3 GPa, due to Hall-Petch strengthening mechanism.…”

Earning trust among high strength material industrialists for its sophistication, thin protective coating has gained its own maturity to date. As a result of active development in the industries, working tool has the capability of fabricating high strength materials with remarkable durability. For example, unwanted tool wear due to thermally softening problems can be avoided. Therefore, the solution for that is protecting the tool with a thin protective coating that can be coated by various coating deposition methods. With the thin protective coating itself possessing remarkable degree of chemical and mechanical properties, the combination of both makes the thin protective coating lead to a useful extend. This paper provides a review of various research activities and various developments in the wear prone industries. Researchers have explored a number of thin protective coatings for the last century to provide a valuable guide for a most practical option. With the state of the art development of the coating methods such as electrodepositing, radio frequency ion source implantation, electron beam implantation, plasma-sprayed coating deposition, flame-sprayed coating deposition, chemical catalytic reduction deposition, vacuum-diffused deposition, vapor deposition, chemical vapor deposition, physical vapor deposition, plasma arc deposition, and some others, this paper presents the continuous development on the enhancement of the capability of the working tool chronologically since the last century. Such development was studied in connection with the ability to outlast the performance of working tool, which elevates expectations that thin protective coatings are no longer extended far beyond.

“…Figure 11, where the light lines correspond to MoN and the dark ones correspond to TiN layers [120,125]. It may be caused by different time evaporation of cathodes and deposition rates of nitride layers [126]. TEM studies of TiN/MoN coatings showed a growth of the columnar structure ( Figure 12).…”

Nanocomposite Multilayer Binary Nitride Coatings Based on Transition and Refractory Metals: Structure and Properties

2019

One area of constant interest in many fields of industry is development of functional multilayer coatings that possess excellent performance characteristics. That is why in our brief review the results of studies of structure and properties of multilayer structures based on binary nitrides of transition or refractory metals obtained by various physical-vapor deposition (PVD) techniques are presented. The influence of substrate temperature, substrate bias voltage, bilayer thickness and interface boundaries on the structure of coatings and their properties, such as hardness, plasticity, wear and corrosion resistance, are discussed in detail. This review may be useful for students and growing community of researchers interested in the synthesis-structure-properties relationship in multilayer coatings based on metal nitrides.

“…On the other hand, the design of multilayer coatings with different composition of bilayers (soft and solid phases) allows to reduce internal stresses and brittleness while high values of hardness from 30 to 45 GPa are maintained [18][19][20][21][22][23][24][25][26][27][28]. One of the promising multilayer systems is the combination of chromium and molybdenum nitrides [29][30][31][32][33][34].…”

The main regularities of the formation of microstructure and properties of multilayer nanostructured CrN/MoN films with periodically changing architecture of layers were considered. The transition metal nitride coatings with high hardness and wear resistance were obtained by vacuum-arc evaporation of the cathodes (Arc-PVD) in nitrogen atmosphere at several sets of predetermined deposition parameters. CrN/MoN multilayers were fabricated using constant nitrogen pressure of 0.4, 0.09 and 0.03 Pa. All samples were divided into three main series depending on the values of bias voltage applied to the substrates (-20,-150 and-300 V). Each serial of samples contain multilayer films varying in the individual layer deposition time and, hence, thickness, which is in range from 1.7 µm to 20 nm. The morphology of surface and microstructure of cross-sections were studied by scanning electron microscopy (SEM). Elemental composition and elemental depth profiles were characterised by energy-dispersive X-ray spectroscopy (EDS), secondary-ion mass spectrometry (SIMS), Rutherford backscattering spectrometry (RBS) and high-resolution transmission electron microscopy (HRTEM) EDS. Micro-and nanostructural analysis of the films was performed by X-ray diffractometry (XRD), grazing incidence XRD (GIXRD), in-plane XRD, electron backscatter diffraction (EBSD) and HRTEM selected area electron diffraction (SAED). The main phases formed in films were two CrN and γ-Mo 2 N nitride phases with cubic lattice of NaCl type and not significant volume of additional metastable MoN cubic phase depending on nitrogen pressure and bias voltage. The preferential orientation of planes changes from [311] to [111] and [200] with the increase of absolute value of bias voltage from-20 V to-150 V and-300 V respectively. The size of nanograins in coatings with a nanometre bilayers thickness was about 12 nm, while micro-deformation of nanocrystallites was about 0.5-0.6%. Coatings with thin nanoscale bilayers have shown high hardness (38-42 GPa) and strong wear resistance, which makes them appropriate and promising for industrial applications as protective ones. The relations between deposition conditions and obtained composition, structure and features were studied. The best parameters and deposition conditions were discussed as recommended to achieve superior mechanical and physical properties of coatings with long lifetime and applicable for harsh environment.
