Improvement of corrosion resistance of biocompatible Zr alloy by elucidation of corrosion mechanism

为了开发新型Zr基生物相容性合金，研究了Zr合金对模拟体液中耐腐蚀性的影响。因此，我们发现合金元素的不同组合及其浓度对合金的耐腐蚀性有提高或降低的作用。此外，在此基础上，我们成功地提高了传统Zr合金的耐蚀性。

The effect of the alloying of Zr to the corrosion resistance in a simulated body fluid was investigated for the purpose of development of novel Zr-based biocompatible alloys. As a result, we found the various combinations of the alloying element and its concentration to improve/degrade the corrosion resistance of the alloy. In addition, we succeeded to improve the corrosion resistance of conventional Zr alloys based on these results.
