制备了一种新型生物可降解生物医用镁合金Mg-Nd-Zn-Zr（以下简称JDBM）。通过析氢、失重和电化学测试，研究了挤压态JDBM合金在模拟体液中的生物腐蚀性能。研究了挤压态AZ 31和挤压态WE 43镁合金的生物腐蚀性能和室温力学性能，并与新型生物可降解医用镁合金JDBM进行了比较。结果表明，挤压态JDBM合金不仅具有较好的室温力学性能，而且在模拟体液中具有较好的生物腐蚀性能。
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.
