The Role of LPSO Structures in Corrosion Resistance of Mg-Y-Zn Alloys

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 performance Mg-LPSO alloys, a set experiments, including microstructure observations and testing media containing various concentrations chloride ions, were carried out. It was shown that main mechanism occurring on not only related volume LPSO structures Mg matrix but also dependent their distribution. chloride-containing solutions, pitting predominant mechanism, increasing concentration, microgalvanic accelerated.
