“…However, the surface of AlCrVN coating ( Figure 1f) was much smoother and exhibited smaller pinhole and micro-particles than other two coatings. The creation of micro-particle, pinhole, and craters on the coating surface was a typical characteristic by using arc ion plating (AIP) method, which could be explained in reference [18].…”

This study focuses on a comparative analysis of AlCrXN (X = Mo or V) coatings with the reference AlCrN coating via arc ion plating technique (AIP). The XRD and XPS results showed that the AlCrXN coatings were mainly composed of fcc-(Cr,Al)N solid solution phases. Both the AlCrMoN and AlCrVN coatings exhibited much higher hardness and adhesive strength than the AlCrN coating. The addition of Mo or V decreased the coefficient of friction (COF) and wear rate, which was due to the formation of lubricant oxides containing Mo or V on the coating surfaces. The cutting results showed that abrasive wear, adhesive wear, and oxidation wear were the main wear mechanisms for the coated tools at the cutting speeds of 60 m/min and 94 m/min. The addition of Mo or V dramatically improved the cutting performance of AlCrXN-coated tools by increasing the anti-wear ability due to the high hardness and the formed lubricant VOx or MoOx films.

“…Multilayer coatings have received specific attention in order to solve these problems. CAE-PVD coating has received much attention because of the unique characteristics that gives to the coating structure [23][24][25][26][27][28]. Creating coatings with a dense, uniform, continuous structure, excellent adhesion to the substrate, good control on the morphology of coatings during deposition using parameter modification, possibility of coating for high melting point coatings and above all possibility of deposition in various coating rates ranging from one nanometer per minute to several micrometers per hours are the remarkable features of the CAE method [29][30][31].…”

The main goal of this study is to compare the electrochemical behavior of CrN/TiN multilayer coating and TiN single-layer coating applied by cathodic arc evaporation (CAE)-physical vapor deposition (PVD) on the substrate of Ti-6Al-4 V in Hank's solution. So, a TiN single-layer coating was formed using PVD method as well as CrN/TiN multilayer coating under totally the same conditions including deposition temperature, working pressure, bias voltage, cathode current and deposition time. To identify the phases in the coatings, X-ray diffraction (XRD) was utilized in order and field emission scanning electron microscopy (FE-SEM) was used in order to study the microstructure of coating. Potentiodynamic polarization (PDP) and electrochemical impedance spectroscopy (EIS) tests were also carried out for corrosion measurements. In the corrosion evaluation, the PDP and EIS tests were performed for the samples after immersion in Hank's solution for 24 hours to reach the steady state. The obtained results from PDP curves showed that the specimen with CrN/TiN multilayer coating exhibited better corrosion behavior than the TiN single-layer coatings. This improvement in corrosion resistance is probably due to the high density of the layers in the CrN/TiN multilayer coating that prevents the penetration of the corrosive solution to the substrate.

“…Transition metals nitride such as ZrN, TiN, and CrN are widely used for industrial applications such as forming dies, cutting tools, mechanical components, and decorations because of their low friction coefficient, high hardness, and good appearance [1,2]. Multicomponent Ti-based nitride coatings such as TiAlN and TiCrN have improved the lifecycles of the coatings due to the effect of solid solutions [3,4].…”

The present study aims to determine the effect of Al on the corrosion resistance of nanostructured TiAlN coatings deposited using a pulsed direct current plasma-assisted chemical vapor deposition (pulsed-DC PACVD) technique. The nanostructured TiAlN coatings were synthesized with three different Al-content values of by distinct precursor's ratio of AlCl 3 -to-TiCl 4 . The number of AlCl 3 -to-TiCl 4 precursor ratios was changed from 1 to 3 in order to vary the Al content. FE-SEM, XRD, EPMA and a Knoop micro-hardness tester were used to characterize the coated surfaces of the specimens. Electrochemical corrosion tests were carried out at 25 ± 1°C to investigate the corrosion behavior of the substrate and the TiN and TiAlN nanostructured coatings in 3.5 wt % NaCl solution. The results indicated that the potentiodynamic polarization plots revealed the passive behavior of TiAlN(2) nanostructured coatings that were more improved than the TiN, TiAlN(1) and TiAlN(3) coatings. Moreover, these curves showed that the TiAlN(2) nanostructured coating had an exceptional polarization resistance that was considered much higher than those of the substrate, TiN, TiAlN(1) and TiAlN(3) coatings. Also, the impedance spectroscopy plots showed that the TiAlN (2) coating had an exceptionally high polarization resistance compared to the substrate and other coatings.
