“…Among all materials, the most stable E OCP is recorded for pure Mg. In 0.01 M NaCl, the initial increase in E OCP for WZ42 is observed weaker resistance of investigated materials to the corrosive environment [30][31][32]. Among all materials, the most stable EOCP is recorded for pure Mg.…”

The growing interest in improving Mg-based alloys’ corrosion properties stimulates the development of Mg-Y-Zn alloys with long-period stacking-ordered (LPSO) structures. In this work, to describe the corrosion performance of Mg-LPSO alloys, a set of experiments, including microstructure observations and corrosion testing in media containing various concentrations of chloride ions, were carried out. It was shown that the main corrosion mechanism occurring on the alloys was not only related to the volume of LPSO structures in the Mg matrix but was also dependent on their distribution. In the chloride-containing solutions, pitting was the predominant corrosion mechanism, and with the increasing chloride concentration, microgalvanic corrosion was accelerated.

“…The highest values of E OCP are noticed for the materials in the least concentrated solution. Together with the Cl − increase, the E OCP decreased, indicating a weaker resistance of investigated materials to the corrosive environment [30][31][32]. Among all materials, the most stable E OCP is recorded for pure Mg.…”

“…Numerous researches have shown that the fine grain can enhance the mechanical performances and corrosion resistance of Mg alloys ( Cui et al, 2021 ; Dobkowska et al, 2021 ; Klu et al, 2022 ). In particular, grain refinement promotes the increase of grain boundaries as corrosion barriers, which can more effectively block the expansion of pitting corrosion.…”

Magnesium (Mg) and Mg alloys are considered as potential candidates for biomedical applications because of their high specific strength, low density, and elastic modulus, degradability, good biocompatibility and biomechanical compatibility. However, the rapid corrosion rate of Mg alloys results in premature loss of mechanical integrity, limiting their clinical application in load-bearing parts. Besides, the low strength of Mg alloys restricts their further application. Thus, it is essential to understand the characteristics and influencing factors of mechanical and corrosion behavior, as well as the methods to improve the mechanical performances and corrosion resistance of Mg alloys. This paper reviews the recent progress in elucidating the corrosion mechanism, optimizing the composition, and microstructure, enhancing the mechanical performances, and controlling the degradation rate of Mg alloys. In particular, the research progress of surface modification technology of Mg alloys is emphasized. Finally, the development direction of biomedical Mg alloys in the future is prospected.
