“…Together with this, it has also been observed that, parallel to the increase of the impingement angles (60°-90°), the erosion rates tend to reduce abruptly. This situation shows that, a similar erosion trend is observed as that seen in literature for ductile materials [13][14][15][16][17]. It was determined that beside the remarkable effects of ZrN coating material also have considerable effects on solid particle erosion wear.…”

The Effects of Solid Particle Erosion of ZrN Coating Material on GF/EP and CF/EP Composites by Using PVD Method ABSTRACTProtective coatings produced by using Physical Vapour Deposition (PVD) method can increase the life time of the components. Therefore; in this study, ≈0.25 m thickness ZrN coatings are applied on Glass Fiber Reinforced Epoxy (GF/EP) and Carbon Fiber Reinforced Epoxy (CF/EP) composites by magnetron sputtering to gain an improved understanding of the erosion resistance. The impingement angles used in the tests were 30, 60 and 90, while the impact velocity was 53 m/s. Al2O3 abrasive particles with an average diameter of 200 m was used. All test specimens regardless of their various properties exhibit maximum erosion rates at 30 impingement angle and thus exhibiting similar behavior as that observed for ductile materials. Optic microscopic views were performed on the surfaces in order to characterize the erosion mechanism. The erodent particles of the both coating layer and composite matrix were found of main role in governing the wear progression. The measured erosion rates were sensitively correlated with the material removal process in order to explain the changes within the coated interfaces.

“…TiN coatings on different substrates under varying process conditions employing 'cathodic arc physical vapor deposition', a different morphologystructure along with hardness, surface roughness, friction coefficient, adhesion strength and overall performance of coated tools have been studied [17][18][19][20][21][22][23][24][25][26][27][28]. 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].…”

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.
