“…According to the methods described by Kim et al [31], a Brinell method was utilized to determine the effects of various parameters on the hardness of the specimens and to draw a plot of the effects of the crack tip size (r ) vs. the applied force ( p). d p/dr was calculated as a factor that indicates the adhesion between the coated layer and the sublayer [32][33][34].…”

This research investigated consecutive multilayer thermal barrier coatings, including Ni 3 Al-Al 2 O 3-Al 2 O 3 /MgO, produced by plasma spray with outer layer thicknesses of 50, 100 and 150 μm deposited on an AISI 316 stainless steel. X-ray diffraction, scanning electron microscopy, Rockwell-B hardness measurements, pin-on-disk wear test and potentiodynamic polarization test were performed to evaluate the specimens. The results revealed that the structure of the produced coatings was completely crystalline. An increase in the coating thickness formed a smooth surface and a low degree of roughness and promoted grain growth. According to the Hall-Petch equation, the degree of hardness decreased from 99 to 92 HRB, and the friction coefficient decreased from 1.25 to 0.6 because of low surface roughness. An adherence test performed with a Brinell hardness test showed that an increase in the layer thickness improved the coating adherence coefficient (d p/dr) from 0.083 to 0.118 kg μm −1. The corrosion test results indicated that the increase in the coating thickness caused a decrease in corrosion current density from 1.1 to 0.008 mA cm −2 .

“…The high crystalline quality of the film, which has an effect on the corrosion resistance, is one of the most important characteristics of the coatings, which can be improved by using the appropriate deposition procedure. Corrosion resistance of ZrN films can be improved by changing the coating parameters [ 40–44 ] and the PVD processes are widely used for deposition of ZrN coating with better corrosion resistance than other methods. However, there is no investigation and understanding of the effect of nitrogen percentage on the corrosion behavior, in hank's solution, of stainless steel AISI 316L coated with Zr‐N by radio frequency magnetron sputtering.…”

Zirconium nitride films are deposited onto stainless steel AISI 316L and silicon (100) by radio frequency magnetron sputtering at different nitrogen flow ratios [N2/(Ar+N2)] varied between 0 and 0.25). Scanning electron microscope, atomic force microscopy, X‐ray diffraction (XRD), and Raman are used to investigate the surface morphology and microstructure of the thin films. The mechanical and electrochemical properties of all coatings are evaluated and compared with the uncoated AISI 316L to explore the efficiency of surface modification. The XRD and Raman analysis show that all the films are crystalline. This shows that the increased nitrogen content leads to a transformation from hexagonal α‐Zr phase to cubic c‐Zr and then to mixed α‐Zr and face centered cubic c‐ZrN phases. The films deposited with nitrogen flow ratio of 0.2 show the highest hardness of 32.2 GPa. Using the potentiodynamic polarization method, the corrosion behavior of the films is studied in Hank's solution. The comparison between uncoated and coated substrates shows a decrease in corrosion current density for all coated samples.

“…Kiahosseini and Larijani [ 30 ] reported that corrosion resistance and adhesion could be improved by modifying the nitrogen admixture. They demonstrated that uniform and crystalline Zr x N y thin films could be fabricated by sputtering on biodegradable metals and alloys, [ 30 ] and furthermore, the films were improved by substrate biasing. [ 31 ] The correlation between the concentration of N vacancies versus the corrosion resistance of Zr x N y films was deliberated by Pei et al [ 32 ] A relatively high content of 0.3 vacancies provided the lowest corrosion rate.…”

Herein, highly crystalline ZrxNy and ZrxNyOz coatings are achieved by the deposition via high‐power impulse magnetron sputtering. Various N2 and N2/O2 gas mixtures with argon are investigated. The chemical composition and, as a result, mechanical properties of the deposited layer can be tailored along with morphological and crystallographic structural changes. The corrosion resistance behavior is studied by potentiodynamic measurements and electrochemical impedance spectroscopy in a sample of synthetic wastewater designed to imitate real‐life domestic wastewater. The corrosion current density of the ZrxNyOz coating is in the range of 33–70 μA cm−2, whereas for the zirconium nitride layers, values below 1.0 μA cm−2 are achieved. The highest corrosion resistance of 64 nm year−1 is observed for the ZrxNy coating deposited with 1.00% N2 content in the gas mixture with a corrosion potential of −0.41 V Ag/AgCl.
