“…The EIS results obtained in both corrosion media, chloride and alkaline, were modeled with the same EEC. The EEC depicted in Figure 8 is composed of two time-constants ( R // CPE ) representing a hierarchically distributed circuit, where the first time-constant, found at high frequencies, corresponds to the passive film-electrolyte interface ( R film // CPE film ), where a non-uniform current distribution along the interface is denoted by the constant phase element of the passive film ( CPE film ) and the resistance of the passive film ( R film ), and the second time constant, found at low frequencies corresponds to the electrochemical double layer represented by ( CPE dl ), including the charge transfer resistance ( R ct ), which is inversely proportional to the corrosion rate ( v corr ), and denotes an electrode process ( R ct // CPE dl ) [ 55 , 56 , 57 ]. The ECC also accounts for the solution ohmic drop denoted by the electrolyte resistance ( R s ).…”

The corrosion behavior of austenitic Fe–Mn–Al–Cr–C twinning-induced plasticity (TWIP) and microband-induced plasticity (MBIP) steels with different alloying elements ranging from 22.6–30 wt.% Mn, 5.2–8.5 wt.% Al, 3.1–5.1 wt.% Cr, to 0.68–1.0 wt.% C was studied in 3.5 wt.% NaCl (pH 7) and 10 wt.% NaOH (pH 14) solutions. The results obtained using potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) techniques, alongside optical microscopy analysis, revealed pitting as the dominant corrosion mechanism in high-Mn TWIP steels. An X-ray diffraction analysis of the surface revealed that the main corrosion products were hematite (Fe2O3), braunite (Mn2O3), and hausmannite (Mn3O4), and binary oxide spinels were also identified, such as galaxite (MnAl2O4) and jacobsite (MnFe2O4). This is due to the higher dissolution rate of Fe and Mn, which present a more active redox potential. In addition, a protective Al2O3 passive film was also revealed, showing enhanced corrosion protection. The highest corrosion susceptibility in both electrolytes was exhibited by the MBIP steel (30 wt.% Mn). Pitting corrosion was observed in both chloride and alkaline solutions.

“…In the Electrochemical impedance spectroscopy (EIS) investigation, the amount of impedance depends on the vertical and horizontal axes. A larger ring diameter means a higher impedance value and higher corrosion resistance 57 . The EISs results showed an irregular semicircle for the substrate and two irregular semicircles for the HZ20 and HZC coatings, which are due to the coating/substrate and coating/solution interfaces.…”

In this article, the effects of the simultaneous addition of the 3 mol % yttria‐stabilized zirconia (3YSZ) and carbon nanotubes (CNTs) reinforcements on different properties of the natural hydroxyapatite (HAP) coating were studied. The electrophoretic deposition (EPD) process was implemented to prepare thin coatings on the Ti6Al4V substrate. The coatings were then sintered at 1000 ° C under vacuum for 2 hr and the mechanical properties of them were studied by the nano‐indentation method. The microsture and phase content of the coatings were investigated by the scanning electron microscope and X‐ray diffraction methods, respectively. The electrochemical properties of the samples were studied by potentiodynamic polarization and electrochemical impedance spectroscopy. The biocompatibility of the coatings was evaluated by the MTT test under standard conditions. It was found that the proper voltage and duration for the deposition of the coatings were 20 V and 4 min, while the longer deposition time of up to 6 min. Was tolerable in the coatings containing 5 wt % of the CNTs. The hardness and Young's modulus of the coatings were improved significantly by the siumultaneous addition of 3YSZ and CNTs, but the effect of nanotubes was more prominent. It was also found that the composite coating had marginally lower biocompatibility, as compared to the natural HAP, which was probably due to their lower roughness. The corrosion resistance of the HAP was not affected by the presence of 3YSZ particles, while the addition of CNTs improved the corrosion resistance of the coatings.

“…The main reason for using Al 2 O 3 ball as the counter body is that both the coating layer and the ball are ceramic materials. 44 Another reason is that Al 2 O 3 is the most common ceramic material used in the tribological applications of nitride-based coatings. 45 In addition, the hardness of Al 2 O 3 ceramic balls is at a level to obtain reasonable results in the investigation of the wear performance of the thin hard films.…”

In this study, TiAlZrN films were coated on the hardened 1.2344 (X 40 CrMoV 5 1) steels using DC power supplied closed field unbalanced magnetron sputtering (CFUBMS) technique. Structural investigations of coatings were carried out using scanning electron microscope and X-ray diffraction. The thickness of coatings was measured from the cross-sectional scanning electron microscope images, and the grain size value and residual stress were calculated by using X-ray diffraction data in the Scherrer formula. Nano indentation method was used to investigate the surface hardness for reducing the substrate effect due to very thin coating thickness (∼2–3 µm). Scratch test was performed for determining the adhesion strength of the coatings. As a tribo-test, a ball-on-disk system was used. From the results, it was understood why TiAlZrN coatings were attractive. The highest hardness was observed as 50.67 GPa, and the highest scratch resistance was reached to 56 N. Also, it was determined that the coating having the highest tribological properties (5.46 × 10−5 mm3/Nm) increased the wear resistance of the substrate six times (3.06 × 10−4 mm3/Nm).
