Selective elimination of a specific component from alloys for providing bone-bonding ability

90 Ti-6Al-4V钛合金中的铝抑制了在人体环境下的自发磷灰石沉积。 我们应用了一种新开发的液相沉积法，不仅可以从合金表面去除Al，而且还可以提供导致磷灰石沉积的沉积层。 此外，我们采用静电纺丝技术来制备二氧化硅纳米管或纤维活性诱导磷灰石沉积和聚合物纤维垫，其中磷灰石在氨蒸气下结晶。

Aluminum in a 90Ti-6Al-4V titanium alloy depresses the spontaneous apatite deposition under the body environment. We applied a newly developed the liquid phase deposition not only to eliminate Al from the alloy surface but also to provide an anatase layer that leads to the apatite deposition. In addition, we employed the electrospinning technique to prepare both silica nano-tube or fibrils active to induce the apatite deposition and polymer fibril mats in which apatite was crystallized under ammonia vapor.
