摘要/Abstract

摘要： 对真空熔炼制备的Zn-5.5Mg-0.4Ba-0.7Gd合金在150 ℃分别时效2、4、8 h,研究时效时间对合金组织及性能的影响。结果表明,时效可以改善合金的微观结构,时效初期合金中的MgZn₂相逐渐转化为Mg₂Zn₁₁相。电化学测试结果表明,时效4 h后合金耐腐蚀性能最佳,自腐蚀电位为-942.844 mV,自腐蚀电流密度为13.34 μA/cm²,微孔电阻为1894 Ω·cm²,电荷转移电阻为1613 Ω·cm²。时效4 h后合金腐蚀产物主要由具有优良的生物相容性的磷酸锌(钙)、碳酸锌(钙)和氢氧化锌组成。

Abstract: Zn-5.5Mg-0.4Ba-0.7Gd alloy prepared by vacuum melting was aged at 150 ℃ for 2, 4 and 8 h respectively. The effect of aging time on microstructure and properties of the alloy was studied. The results show that aging can improve microstructure of the alloy. At the beginning of aging, MgZn₂ phase in the alloy gradually transforms into Mg₂Zn₁₁ phase. The electrochemical test results show that the alloy aged for 4 h has the best corrosion resistance, the self corrosion potential is -942.844 mV, and the self corrosion current density is 13.34 μA/cm², the micropore resistance is 1894 Ω·cm², and the charge transfer resistance is 1613 Ω·cm². The corrosion products of the alloy aged for 4 h are mainly composed of zinc phosphate (calcium), zinc carbonate (calcium) and zinc hydroxide with excellent biocompatibility.
