摘要
选择具有高生物相容性的Mg_(65)Zn_(30)Ca_3Si_(1.766)Zr_(0.234)合金体系作为研究对象,从原料单质粉末开始,采用雾化制粉、球磨制得该合金的非晶粉末,再通过X射线衍射(XRD)、差示扫描量热法(DSC)、电化学测试等手段,研究了球磨所制得粉末的非晶程度、非晶合金的热力学性能以及该体系镁基非晶合金的耐腐蚀性能.研究表明,经过80h以上的球磨,可以使该体系下的镁基合金完全转变为非晶态,并且其耐腐蚀性能在相同情况下较ZK61晶态合金更为良好.
Mg65Zn30Ca3Si1.766Zr0.234 alloy with verified high biocompatibility is investigated in this study.The amorphous powder is prepared by gas atomization and ball milling.Structure,thermodynamic property and corrosion resistance of the power are characterized by X-Ray diffraction（XRD）,differential scanning calorimetry（DSC）and electrochemical measurement.The results indicate that the Mg-based alloy can transform to amorphous status after ball-milling for more than 80 hours.The corrosion resistance of amorphous alloy is better than that of ZK61 alloy under the same condition.Therefore,the Mg-based amorphous alloy prepared by mechanical alloying show great potential application in the future.
