Mg alloys containing long period stacking ordered (LPSO) structures possess excellent mechanical properties and corrosionresistance, exhibiting great application potential in biodegradable implants. The corrosion process of different LPSOphases in the Mg alloys need to be furtherly clarified in different solution environments. In this paper, we mainly reviewedthe influencing factors on the corrosion behavior of LPSO-containing Mg alloys, including the alloying elements, processingtechnologies, and the types, volume fractions and distributions of LPSO phases. Recent researches are well summarized withan emphasis on their corrosion mechanism. Special attention is given to the key issues for LPSO-containing Mg alloys asbiomedical implants, with their biodegradation behavior comprehensively discussed. The motivation is to provide theoreticalsupport for the possible application of LPSO-containing Mg alloys in the biomedical field.
