“…Comparative analysis shows that the coatings are erased, but not peeled during scratching. That is cohesive failure associated with plastic deformation [23][24][25], and formation of fatigue cracks in the coating's material takes place. The cohesive strength of multi-component coating (Zr-Ti-Cr-Nb)N was determined from the measurements (L C = 62.06 N).…”

This work presents the results of (Zr-Ti-Cr-Nb)N superhard coatings research. The samples were fabricated by the vacuum-arc deposition method (Arc-PVD). Structure, composition and properties of these coatings were studied. The study of coatings was carried out using scanning electron microscopy, energy dispersive spectroscopy, and X-ray diffraction. Hardness measurements and adhesion tests were performed. The coatings thickness was up to 6.2 µm, nanocrystallites sizes ranged from 4 to 7.3 nm. Values of hardness and cohesive strength were H = 43.7 GPa and LC = 62.06 N, respectively. The optimal conditions for coating deposition were found.

“…In addition to these studies, there are several other available studies in the literature targeting TiN coatings along with their processing techniques and analyses [29][30][31][32][33][34][35][36]. In addition to TiN coating, different types of hard coatings developed under various conditions have also been published extensively [37][38][39][40][41][42][43][44][45][46][47][48]. The basic idea discussed in those studies is related to the properties and characteristic of deposited coatings, which are subjected mainly to the change of process parameters, types of material and processing approach.…”

Coatings of suitable materials having thickness of few atoms to several microns on a substrate have caught the regular attention of scientific community working in various fields of science and technology. Decorative and protective coatings, transparent and insulating coatings, coatings of medical implants and surgical instruments, coatings for drug delivery, ultra-precision machine-tool coatings and coatings for miscellaneous uses are in the routine demand. Different hard coatings develop under the significant composition of suitably different natured atoms where their force-energy behaviors, when in their certain transition states, provide the provision to bind (adhere). In the binding mechanism of different nature suitable atoms, electron (of outer ring) belonging to filled state gaseous nature atom takes another clamp of energy knot (of outer ring) belonging to unfilled state solid-natured atom. Set conditions of the process provide the provision of binding different nature atoms in a technique or method meant for it. Different natures of atoms develop structure in the form of hard coating by locating ground points between their original ones where gaseous nature atoms increase potential energy under the decreasing levitational force at electron-level while the solid atoms decrease potential energy under the decreasing gravitational force at electron-level. Ti–Ti binding occurs through the difference of expansion of their energy knots nets when one atom just lands on the already landed atom while the adhered nitrogen atom incorporates at their interstitial position. Under suitable set parameters, differently natured atoms deposit in the form of coating at substrate surface under the given conditions. The rate of solid-natured atoms ejecting or dissociating from the source depend on its nature, process parameters and the processing technique or approach. In random arc-based vapor deposition system, depositing differently natured atoms at substrate surface depends on the input power. In addition to intrinsic nature of atoms, different properties and characteristics of coatings emerge as per engaged forces under the involved energy. The present study sets new trends in the field of coatings involving the diversified class of materials and their counterparts.

“…In this connection one may expect a considerable sensitivity to the physicotechnical param eters of the deposition of structural states and properties of coatings based on MoN and CrN as layers of a mul tilayer system. The highest effects may be expected in the case that the layers are of nanometric thicknesses, which stems from the fact that nitrides exhibit the highest mechanical properties in this dimensional range [10][11][12].…”

Abstract-A complex study has been performed of the effect of the technological parameters, which are responsible for the energy states of deposited particles, on the elemental, phase and structure composi tions, hardness, and tribological characteristics of formed vacuum-arc multilayer Mo 2 N/CrN systems with a nanometric thickness. The formation of two phase and structure types has been defined in combined nitride layers: γ Mo 2 N/CrN with the isostructural cubic crystalline lattices and γ Mo 2 N/CrN with non isostructural cubic and hexagonal lattices.
