摘要

采用电化学方法测定了不同成分的Ti Fe Mo Mn Nb Zr合金在Hank’s人工模拟体液中的阳极化曲线。通过回归拟合方法得到了各成分组合的腐蚀动力学参数。采用BP神经网络系统建立了Fe

Nb元素的成分组合与腐蚀动力学参数之间的非线性关系及各元素质量分数与腐蚀速度的关系

并通过试验进行了验证

预测结果与实际测定结果相符合

Abstract

Passivation anodized curves of Ti-Fe-Mo-Mn-Nb-Zr alloys with various constituents have been measured by electrochemical technology in Hank’s artificial body fluid. Erode dynamic parameters were obtained by regression analysis. Based on BP artificial neutral network system

the non-linear relation between various compositions of Fe

Nb elements and erode dynamic parameters as well as the relation between weight fraction of different components and erode rate were established. The experimental results verified that the predicted results were well in agreement with the actual measured results.
