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). © 2012 Elsevier Ltd.
