Abstract
A new type of patented biodegradable biomedical magnesium alloy Mg–Nd–Zn–Zr (hereafter, denoted as JDBM) was prepared in this study. The biocorrosion properties of the as-extruded JDBM alloy were investigated in simulated body fluid (SBF) by hydrogen evolution, mass loss and electrochemical tests. The biocorrosion properties of as-extruded AZ31 and as-extruded WE43 alloys as well as the mechanical properties at room temperature were also studied in order to compare with the novel JDBM biodegradable biomedical magnesium alloy. The results show that the as-extruded JDBM alloy not only owns much better mechanical properties at room temperature but also exhibits much better biocorrosion properties in SBF.
