The corrosion resistance of materials composed of metal is an essential property for preventing material deterioration caused by corrosion. In this study, we demonstrate that corrosion resistance can be significantly improved through the electrodeposition of molybdenum oxide onto a metal plating containing iron-group elements. Mo oxide can be electrodeposited using a simple plating bath, low current density, and short deposition time, exhibiting a fascinating metallic gloss appearance. GI-XRD and XPS analyses revealed that amorphous Mo oxide adhered to the substrate by a seed layer partially reduced to metallic Mo by the iron-group element in the substrate, based on the principle of “induced co-deposition.” A Mo oxide coating with a thickness of approximately 100 nm decreases the corrosion current density of Ni-W plating by approximately 5 times and the passivation current density by approximately 10 times in a 3 mass% NaCl solution. Mo oxide coatings represent an attractive strategy for improving the corrosion resistance of various metal materials containing iron-group elements.

“…The protective coating technology is the most widely used of the many protection strategies. This technology usually uses techniques such as physical vapor deposition, 3,4 anodic oxidation, 5,6 chemical conversion films, 7,8 thermal spraying, 9,10 and micro-arc oxidation 11,12 to form a covering layer on a metal substrate surface to protect the metal by minimizing direct contact between the metal and the corrosive medium. Although these surface treatment techniques are effective in avoiding corrosion of metals, the complexity and high cost of the operation greatly limit the application of these techniques.…”

“…Generally, increasing the Zinc coating thickness and adding metallic components, such as Al and Mg, are considered to improve the corrosion resistance of HDG, which combines the sacrificial protection of Zn based alloy and the physical barrier of Al oxide film [4][5][6][7][8]. However, the conventional process for HDG often entails drawbacks, including catalyst impurities and large resource consumption to maintain a molten bath [9,10]. Therefore, alternative methods have been proposed.…”

Double layers composed of Sn and Mg, each 0.8 μm thick, were fabricated on a hot-dip galvanized steel (8.4 μm) sheet using DC magnetron sputtering and post-annealing processes. With an increase in temperature, the surface morphologies were agglomerated with each other. Additionally, Sn/Mg mixture sites, including an intermetallic compound of Mg2Sn, were formed at 190 °C and locally clustered at 220 °C. In the salt-spray test, the corrosion resistance of the Sn/Mg film prepared at 190 °C was 960 h, which is longer than that at non-heat for 528 h or 220 °C for 480 h. In the polarization test, the Sn/Mg film formed at 190 °C displayed a lower corrosion current density of 1.07 μA/cm2 and potential of 1.62 V/SSCE than those at non-heat or 220 °C.
