“…3). It is clear how the macroparticle has grown since the beginning of the deposition and the gradual development of macroparticles during the entire coating deposition is also observable in the image [20][21][22][23][24][25]. Macroparticles formed during the deposition in the coating structure can adversely affect the overall properties of the substrate-coating system.…”

The continuous development of thin coatings for different applications and using various coating methods require the characterization of these newly formed surfaces to evaluate their utility properties. Binary thin coatings of titanium (TiN) and zirconium (ZrN) nitrides were prepared using the Arc-PVD (Cathodic Arc Deposition) method. Differences were observed in the structure and morphology of the thin coatings and the change in tribological properties at room and elevated temperatures (150 °C and 300 °C). The research is focused on evaluating the frictional properties of the coating using the Ballon-Disc method in the dry friction mode. The emphasis is placed on the resistance of the thin coating to wear. The nanohardness was measured to be 26.2 GPa for TiN and 24.8 GPa for ZrN. Index of resistivity against plastic deformation H³/E² (plastic deformation resistance) for ZrN coating -0.087 and TiN coating -0.095, H/E (plasticity index) for ZrN -0.059 and TiN -0.060. Better friction properties and wear resistance (at 150 °C) were found for the TiN coating compared to the ZrN coating.

“…The different atom sizes, while increasing the lattice distortion, may also weaken the interatomic bonding or form a eutectic structure, both of which would reduce the melting temperature of the target material. Alternatively, to reduce droplet formation, measures can be taken to effectively cool the cathodes or to accelerate the arc spot motion to reduce the size of the melt pool [31]. Another approach is utilizing filtering techniques to remove the molten droplets using an electric or magnetic filter [43].…”

Microstructure, Mechanical Properties, Wear and Erosion Performance of a Novel High Entropy Nitride (AlCrTiMoV)N Coating Produced by Cathodic Arc Evaporation

2023

(AlCrTiMoV)N high entropy nitride film was prepared on 17-4PH stainless steel substrate using cathodic arc evaporation (CAE). The composition, microstructure, and thermal stability were investigated using scanning electron microscopy (SEM), transmission electron microscopy (TEM), and X-ray diffraction (XRD). Mechanical properties such as hardness and Young’s modulus and coating performance against wear and erosion were also evaluated. The results show that the (AlCrTiMoV)N coating assumes a single-phased solid solution B1 FCC structure. It has excellent thermal stability and retains its structure with no decomposition observed up to a temperature of 1000 °C. The hardness and elastic modulus are measured as 21.3 GPa and 304 GPa, respectively. The coating contains some metallic droplets. As a potential protective coating, the (AlCrTiMoV)N coating has a lower wear rate but a higher erosion rate when compared to the TiN baseline coating.

“…Several explanations were proposed, including blocking of dislocations by layer boundaries, Hall–Petch hardening, deformation effects at layer boundaries, and the effect of super hardness [ 30 ]. Reducing the thickness of the bilayer down to the nanoscale at a constant value of the total thickness of the coating makes it possible to increase the number of interfaces between the layers, which act as a barrier to dislocation migration and the propagation of microcracks [ 31 , 32 ]. A deeper understanding of this issue is the basis for the subsequent development of functional multilayer coatings.…”

Effect of Bilayer Thickness and Bias Potential on the Structure and Properties of (TiZr/Nb)N Multilayer Coatings as a Result of Arc-PVD Deposition

This work is devoted to the study of the formation of nanostructured multilayer coatings (TiZr/Nb)N on the surface of an AISI 321 steel substrate depending on the deposition parameters of the Arc-PVD method. The results of the X-ray diffraction analysis showed the formation of solid solution (TiNb)N and ZrN in the multilayer coatings with an FCC structure, ε-NbN with a hexagonal structure, as well as with a small volume fraction of the ε-Ti2N and β-Nb2N phase. On the basis of phase composition data, it is possible to assume that an increase in the number of bilayers leads to a decrease in the nitrogen concentration in the bilayers and, consequently, to a decrease in the volume fraction of ε-NbN and β-Nb2N nitrides. In all investigated systems obtained at −100 V and −200 V bias potentials, ε-NbN is the main phase. The study of the element distribution over the thickness of the (TiZr/Nb)N coating confirms the results of the X-ray diffraction analysis. The use of the structure model in the form of alternating layers allows for significantly improving the adhesion characteristics of the protective coating, as well as ensuring their high hardness. Based on the experimental results, it is possible to analyze changes in the mechanical and tribological properties of multilayer coatings depending on the number of applied bilayers. The results of the study of the elastic modulus and hardness of multilayer coatings (TiZrNb)N with different numbers of bilayers showed that a large number of bilayers (small thickness of each individual layer) shows the lowest value of hardness. It is assumed that as the bilayer thickness decreases, the coating characteristics are closer to the monolayer alloy than to the multilayer structure.
