摘要：

Magnesium and its alloys have attracted extensive attention as a prospective bioimplant. We have successfully employed chemical treatment in the presence of H2O2 to modify the surface and the effect of treatment was investigated in simulated body fluid environment. The electrochemical techniques were used to assess the corrosion protection performance of the AZ91 Mg alloy in SBF solution, while FT-IR, SEM and EDX analyses were carried out to envisage the surface characteristics, and XRD and XPS techniques were performed to further substantiate the findings. The results revealed that the surface treated magnesium alloy could serve as a better bioimplant material. (C) 2014 The Korean Society of Industrial and Engineering Chemistry.
