| Abstract Scope |
Bioresorbable magnesium fibers (filaments or wires) have a large potential for biomedical applications, such as wound closure, orthopedics, bioresorbable electronic sensors, nerve repair, etc. WE43 Mg alloy wires were manufactured by successive cold drawing and annealing steps at high temperature to reach an optimum combination of mechanical properties. Afterwards, they were surface-modified by plasma electrolytic oxidation using a novel continuous process. The microstructure, mechanical properties and degradation rate in simulated body fluid as well as the cytocompatibility of the wires was assessed by means on vitro tests in simulate body fluid. It was found that the presence of a compact oxide layer of a few µm in thickness was critical to avoid localized corrosion, maintain mechanical properties for longer times and limit the reactivity of the wires to ensure excellent biocompatibility. |
