Abstract

Rapid degradation is the major obstacle hindering a wider use of magnesium based biomaterials. In this work, silicon, one of the essential elements in the bone tissues, is implanted into WE43 magnesium alloy to improve its corrosion behavior. X-ray photoelectron spectroscopy (XPS) reveals the formation of a gradient surface structure with a gradual transition from a Si-rich oxide layer to Si-rich layer. Electrochemical studies reveal that Si implantation offers a remarkable improvement in the corrosion resistance of WE43 Mg alloy in simulated body fluid (SBF).

► Silicon, an essential element for the bone, is implanted into Mg alloy for the first time. ► A surface layer with Si in the oxidized state is formed on Mg alloy. ► Silicon ion implantation results in excellent corrosion resistance in vitro.
