the developed short-time method resulted in a change of corrosion mechanism present at OCP and cannot be considered applicable, in particular when comparing and, thus, underestimating fatigue strength of PEO modified versus bare metallic Mg alloys. However, the elaborated method can be considered as worst-case testing to generally exclude unsuitable non-surface modified Mg alloys already in early stages and before expensive preclinical studies.
