With the help of supersonic fine particle bombardment technology, a gradient nanostructure with a certain layer depth was constructed on the surface of an Mg-1.8Zn-0.5Zr-1.5Gd biological magnesium alloy. The effects of bombardment time on the microstructure, mechanical properties, and corrosion resistance of the gradient nanostructure were investigated. The results showed that the layer depth and surface roughness of the gradient nanostructures increased with an increase in the bombardment time, and the corresponding mechanical properties and corrosion resistance first increased and then decreased with an extension of the bombardment time. When the bombardment time was 30 s, the alloy had good mechanical properties and corrosion resistance. Its tensile strength, yield strength, elongation, and static corrosion rate were 299.1 ± 2.2 MPa, 264.4 ± 1.5 MPa, 36.8 ± 1.3 %, and 0.307 ± 0.015 mm y − 1 , respectively. The results of the 120-h immersion experiment in simulated human body fluids showed that the average corrosion rate of the alloy first decreased, then increased, and finally decreased with an extension of the immersion time and finally tended
利用超声细粒子轰击技术，在Mg-1.8Zn-0.5Zr-1.5Gd生物镁合金表面构建了具有一定层深的梯度纳米结构。研究了轰击时间对梯度纳米结构的微观结构、力学性能和耐蚀性的影响。结果表明:随着轰击时间的增加，梯度纳米结构的层深和表面粗糙度增大，相应的力学性能和耐蚀性随轰击时间的延长先增大后减小;当轰击时间为30 s时，合金具有良好的力学性能和耐腐蚀性。其抗拉强度为299.1±2.2 MPa，屈服强度为264.4±1.5 MPa，伸长率为36.8±1.3%，静态腐蚀率为0.307±0.015 mm y−1。在模拟人体体液中浸泡120 h的实验结果表明，合金的平均腐蚀速率随着浸泡时间的延长先降低后升高，最后降低并趋于平缓
