“…The larger semicircle is caused by the compact thin film and appears at lower frequencies. The semicircle at the low-frequency region for the ZnO curve is associated with the charge transfer resistance at the electrode/electrolyte interface [72]. With the increasing deposition times of ZnO thin films, ions will have difficulty penetrating pores and film defects, which leads to an increase in the charge transfer resistance of ZnO thin films.…”

This investigation aims to improve the properties of 304 L stainless steel (SS) substrates for use in corrosion, mechanical, and biomedical applications by depositing ZnO thin films. The ultrasonic spraying technique was used to prepare ZnO thin films with depositional times of 1, 4, and 9 minutes. XRD and Raman studied the surface characteristics of ZnO samples. XRD analysis revealed a hexagonal structure with an average crystallite size of 22 nm for ZnO. Indentation nano measurements indicated an increase in the hardness of the films examined. To determine the type of conductivity and estimate the charge carrier density, potentiodynamic polarization, electrochemical impedance spectroscopy (EIS), and Mott-Schottky analysis were performed. The thin film deposited for 9 minutes was found to be the most effective in improving corrosion resistance.

“…They showed that the equilibrium E corr of the ZnO films before salt spray test was positively shifted compared to that of bare stainless steel. They claimed that the shift in E corr can be attributed to the improved corrosion resistance of the coated samples [ 16 ]. Also, Hosseini et al reported the anticorrosion properties of Polypyrrole (PPy) and PPy-ZnO coating on mild steel and observed the incorporation of ZnO nanorods in the PPy coating resulted in the positive shift of E corr value, indicating improved corrosion protection [ 29 ].…”

“…Kumar et al coated the SS specimen (304 L SS) by depositing nanoparticles of ZnO in 2018. Electrochemical Impedance Spectroscopy and Tafel plot parameters of the electrochemical corrosion tests indicated that the anticorrosion properties of the coated thin films were substantially higher than that of bare steel [ 16 ]. Ming Liu et al [ 17 ] investigated corrosion and passive film characteristics of 3D-printed NiTi shape memory alloys in artificial saliva.…”

Background Releasing of metal ions might implicate in allergic reaction as a negative subsequent of the corrosion of Stainless Steel (SS304) orthodontic wires. The aim of this study was to evaluate the corrosion resistance of zinc-coated (Zn-coated) SS orthodontic wires. Methods Zinc coating was applied on SS wires by PVD method. Electrochemical impedance spectroscopy (EIS), Potentiodynamic polarization tests and Tafel analysis methods were used to predict the corrosion behavior of Zn-coated and uncoated SS wires in both neutral and acidic environments. Results The values of Ecorr ,icorr and Rct ,which were the electrochemical corrosion characteristics, reported better corrosion behavior of Zn-coated SS wires against uncoated ones in both artificial saliva and fluoride-containing environments. Experimental results of the Tafel plot analyses were consistent with that of electrochemical impedance spectroscopy analyses for both biological solutions. Conclusion Applying Zn coating on bare SS orthodontic wire by PVD method might increase the corrosion resistance of the underlying stainless-steel substrate.

“…The considerable wide band gap of n-type semiconductor ZnO makes it outstanding in all rounds of applications mostly in optoelectronics application. The anticorrosion behavior of nanostructured ZnO thin films on 304L stainless steel was investigated by Muhamed et al [37]. The authors observed thatthe anticorrosion behavior of 304L steel improved with coated ZnO thin films.…”

The microstructures, electrochemical, and hardness properties of deposited Ni-doped ZnO thin films on ultrasonically cleaned 316L stainless steel (316L ST) employing a low-cost chemical spray pyrolysis technique (CSPT) was examined in this work. The films were prepared at various concentrations using commercially available purity zinc acetate and nickel acetate as the precursor sources. The result of x-ray diffractometry (XRD) showed that the films have polycrystalline structure with all the films consisting of single phase ZnO hexagonal wurtzite structure. Scanning electron microscopy (SEM) result affirmed that the coated films adhered to the substrates and equally spread through the substrate surfaces. The surface microstructure of the 316L ST improves with Ni content. The corrosion resistance of the 316L ST was observed to improve with the coated films. Hardness value of the uncoated 316L ST was observed to increase from 139.15 HV to 233.03 HV of coated S3 (9% nickel acetate (0.2 M) and 91% zinc acetate (0.2 M)).
