Evolution of Atomic-Level Interfacial Fracture Mechanics in Magnesium-Zinc Compounds Used for Bioresorbable Vascular Stents.

With the increase in the IMC thickness at the interface, the maximum tensile stress shows an increasing trend, which means that the interlaminar compounds at the Mg-Zn interface can strengthen the mechanical properties between the Mg-Zn interface, which brings the advantage that the risk of delamination between the Zn coating and the Mg matrix is prevented due to the presence of Mg-Zn interface compounds in the dilation process of the Mg matrix Zn coating vascular stent.
