为了了解新型钛合金的组成金属元素钛、锆、铌和钽的骨形成能力，将这些金属浸入含有钙和/或磷酸根离子的各种电解质中，并使用X射线光电子能谱进行表征。此外，进行电解质中的金属的阴极极化以评估电解质中的金属上的表面氧化膜的稳定性。在含有钙和磷酸根离子的电解质中在Ti上形成的磷酸钙层相对保护整个层的传质。然而，在Zr上形成的磷酸锆层比在Ti上形成的磷酸锆层更具有保护性和稳定性。因此，未掺入钙离子。Nb和Ta形成磷酸钙，但量小于Ti中的量，因为在Nb和Ta上形成的磷酸盐具有一定的保护性，并且钙离子的掺入被抑制。钛对磷酸钙的形成起着最重要的作用，而锆则抑制了钛合金上磷酸钙的形成。通过钛合金的设计来控制骨形成是可行的。版权所有© 2015约翰威利父子有限公司.
To understand the bone formation ability of constituent metal elements of new titanium alloys, titanium, zirconium, niobium, and tantalum, these metals were immersed in various electrolytes containing calcium and/or phosphate ions and characterized using X‐ray photoelectron spectroscopy. In addition, cathodic polarization of the metals in the electrolytes was performed to evaluate the stability of the surface oxide films on the metals in the electrolyte. The calcium phosphate layer formed on Ti in electrolytes containing calcium and phosphate ions is relatively protective against mass transfer throughout the layer. However, the zirconium phosphate layer formed on Zr is much more protective and stable than that on Ti. Therefore, calcium ions were not incorporated. Nb and Ta formed calcium phosphate, but the amount was smaller than that in Ti, because phosphates formed on Nb and Ta are somewhat protective and the incorporation of the calcium ion is inhibited. Titanium played the most important role in forming calcium phosphate, while zirconium inhibited the formation of calcium phosphate on titanium alloys. The control of bone formation is feasible by the design of titanium alloys. Copyright © 2015 John Wiley & Sons, Ltd.
