In this study, pore shape changes and apatite formation on zinc (Zn) and silicon (Si) ion-doped hydroxyapatite (HA) films of Ti-6Al-4V by plasma electrolytic oxidation (PEO) treatment has been investigated by several techniques. The PEO films and the Ti-6Al-4V surface after immersion in SBF were observed by X-ray spectroscopy, field-emission scanning electron microscopy, and energy dispersive X-ray spectroscopy. The number of pores decreased as Zn ion concentration increased from 5Zn to 10Zn. The maximum size of pores were increased from 5Zn to 20Zn concentration, whereas, the minimum size of pores decreased. The amount of bone-like apatite formation for the 5Zn/5Si sample was higher than those of other samples immersed in SBF.
在本研究中,通过多种技术研究了经等离子体电解氧化(PEO)处理的Ti-6Al-4V锌(Zn)和硅(Si)离子掺杂羟基磷灰石(HA)薄膜的孔形状变化和磷灰石形成。通过X射线光谱、场发射扫描电子显微镜和能量色散X射线光谱观察了浸泡在模拟体液(SBF)中的PEO薄膜和Ti-6Al-4V表面。随着Zn离子浓度从5Zn增加到10Zn,孔的数量减少。孔的最大尺寸从5Zn浓度增加到20Zn浓度,而孔的最小尺寸减小。5Zn/5Si样品形成的类骨磷灰石量高于浸泡在SBF中的其他样品。
