“…A load level of 2 N was applied, and the friction coefficient was recorded synchronously. Figure 4 shows the dry-slip friction coefficient (no unit) curve of MAO coating at 1,800 s. The different friction coefficient reflects the physical and chemical properties, mechanical properties, hardness and wear resistance of the coating and the bonding strength between the coating and the substrate (Dib et al, 2020;Fan et al, 2022;Song and Wan, 2023). The initial friction coefficient of MAO coating on cast ZM5 is higher than that of rolled ZM5.…”

Purpose The impact of rolling on the performance of micro arc oxidation (MAO) coatings on ZM5 alloy has been underreported. The purpose of this study is to explore the correlation between rolling and the failure mechanism of MAO coatings in greater depth. Design/methodology/approach The influence of rolling on the corrosion and wear properties of MAO coating was investigated by phase structure, bond strength test (initial bond strength and wet adhesion), electrochemical impedance spectroscopy and wear test. The change of the surface electrochemical properties was studied by first principles analysis. Findings The results showed that the MAO coating on rolled alloy had better corrosion and wear resistance compared to cast alloy, although the structure and component content of two kinds of MAO coating are nearly identical. The difference in interface bonding between MAO coating and Mg substrate is the primary factor contributing to the disparity in performance between the two types of samples. Finally, the impact of the rolling process on MAO coating properties is explained through first-principle calculation. Originality/value A comprehensive explanation of the impact of the rolling process on MAO coating properties will provide substantial support for enhancing the application of Mg alloy anticorrosion.

“…The eutectic high-entropy alloys (EHEAs) like AlCoCrFeNi 2.1 is also in the scope of the Special Issue. In the work [ 10 ] corrosion behavior of the AlCoCrFeNi 2.1 in chloride-containing sulfuric acid solution at different temperatures were studied. The effects of temperature on the passive and local corrosion mechanism of EHEA were discussed.…”
