“…Among the three samples, the Cr concentration of the passive film surface that formed on A0, A1, and A2 samples is approximately 11.1 at %, 11.8 at %, and 10.3 at %, which is in a trend of A1 > A0 > A2. The surface enrichment of the Cr element could accelerate the formation of a passive film with greater resistance to the attack of Cl – ions in acid media [ 54 ]. Therefore, a better corrosion-resistant performance can be expected for the A1 sample.…”

This study investigated the structural heterogeneity, mechanical property, electrochemical behavior, and passive film characteristics of Fe–Cr–Mo–W–C–B–Y metallic glasses (MGs), which were modified through annealing at different temperatures. Results showed that annealing MGs below the glass transition temperature enhanced corrosion resistance in HCl solution owing to a highly protective passive film formed, originating from the decreased free volume and the shrinkage of the first coordination shell, which was found by pair distribution function analysis. In contrast, the enlarged first coordination shell and nanoscale crystal-like clusters were identified for MGs annealed in the supercooled liquid region, which led to a destabilized passive film and thereby deteriorated corrosion resistance. This finding reveals the crucial role of structural heterogeneity in tuning the corrosion performance of MGs.

“…The Tafel extrapolation method was used to calculate the corrosion potential ( E corr ), corrosion current density ( I corr ), Tafel anode slope (β a ), and Tafel cathode slope (β c ), and the results are listed in Table . A displacement of E corr greater than 85 mV could be considered as an anodic or cathodic corrosion inhibition mechanism, and the CNZO coating E corr value shifted the most in the positive potential direction relative to the blank coating, 89 mV, indicating that the corrosion inhibitor acted as an anodic inhibitor. In addition, the cathodic curves of all samples did not show the typical plateau area due to dissolved oxygen reduction, indicating that the cathodic reaction was basically under charge transfer control .…”

The micromagnetic field of magnetic materials helps to improve the anticorrosion properties, so magnetic enhancement measures may bring considerable corrosion inhibition ability. Based on the magnetic generation mechanism of ZnO, the concentration of oxygen vacancy in the crystal lattice was regulated by the doping of magnetic metal Co, the introduction of nonmetallic N, and light treatment, so as to achieve a gradual increase in magnetism. The increased magnetism meant that micromagnetic fields could control electron transport to a greater extent, slowing the rate of corrosion. Moreover, an external magnetic field was applied to the corrosion system and resulted in the formation of a dense secondary protective film on the surface. Results showed that for the corrosion resistance of Co/N codoped ZnO (CNZO) dilute magnetic solid solutions (DMSs), the composite impedance value increased by 1204.0% compared to the pure epoxy coating, and the impedance value increased again by 4100 ohm·cm2 after the application of an external magnetic field and is 5.73 times that of ZnO. This work also confirmed that the magnetic properties of ZnO-based DMSs were positively correlated with the corrosion resistance, which provided guidance for the design of corrosion inhibition materials in other systems.

“…Al and Ti were, in fact, firstly chosen as the major elements because AlTiN coating has demonstrated outstanding mechanical properties and tribological performance and has been widely used for cutting tools [22][23][24]. Cr, V and Mo elements were also incorporated into the coating, with the goal to improve the thermal stability [25], oxidation/corrosion resistance and solid lubricity of the coating [26,27]. This composition continues to build upon existing (AlCrTiV)N, which was reported to have excellent mechanical properties [28].…”

(AlCrTiMoV)N high entropy nitride film was prepared on 17-4PH stainless steel substrate using cathodic arc evaporation (CAE). The composition, microstructure, and thermal stability were investigated using scanning electron microscopy (SEM), transmission electron microscopy (TEM), and X-ray diffraction (XRD). Mechanical properties such as hardness and Young’s modulus and coating performance against wear and erosion were also evaluated. The results show that the (AlCrTiMoV)N coating assumes a single-phased solid solution B1 FCC structure. It has excellent thermal stability and retains its structure with no decomposition observed up to a temperature of 1000 °C. The hardness and elastic modulus are measured as 21.3 GPa and 304 GPa, respectively. The coating contains some metallic droplets. As a potential protective coating, the (AlCrTiMoV)N coating has a lower wear rate but a higher erosion rate when compared to the TiN baseline coating.
