Corrosion behavior of Mg72Zn27Pt1 alloy in Hanks’ solution: comparison between amorphous and crystalline structures
The corrosion resistance and mechanisms of the Mg72Zn27Pt1 alloy with different structures (amorphous and crystalline) were investigated in Hanks’ solution at 37 °C. It was found that the corrosion current density of crystalline Mg72Zn27Pt1 is 15 times higher than that of amorphous Mg72Zn27Pt1. The obtained results also suggest that the same electrochemical reactions occur during corrosion of both variants, but the main difference is the propagation of cracks in the crystalline Mg72Zn27Pt1. No cracks are detected during corrosion of amorphous Mg72Zn27Pt1. The results published in the literature would allow us to assume that cracking could be attributed to an increase in mechanical deformation due to hydrogen uptake by the crystalline Mg72Zn27Pt1.
