Plasma electrolytic oxidation coating with sustainable corrosion protection through addition of Y2O3 nanoparticles at ultra-high frequency pulse current
This work aims to design and validate the synergistic effects of ultra-high frequency and Y2O3 nanoparticles on sustainable corrosion resistance of plasma electrolytic oxidation (PEO) upon Mg alloys. Incorporation of Y2O3 nanoparticles into PEO coatings was efficient, with preferential growth on coating surface and within discharge channels. In particular, a high concentration of Y2O3 nanoparticles, up to 20.6 at.%, was observed in PEO coating prepared at the highest frequency (20 kHz) pulse current. Y2O3-based compounds such as YOOH and Y(OH)3 present within PEO coating exhibit superior electrochemical stability, thereby enhancing overall stability and corrosion resistance.
期刊介绍：
Applied Surface Science covers topics contributing to a better understanding of surfaces, interfaces, nanostructures and their applications. The journal is concerned with scientific research on the atomic and molecular level of material properties determined with specific surface analytical techniques and/or computational methods, as well as the processing of such structures.
