功能化种植体展示了骨科种植体的升级方法,旨在通过改进生物整合实现长期成功。多功能的生物陶瓷涂层由于其结合了生物植入物所必需的各种性能,如骨整合和抗菌特性,已成为传统涂层的有效替代品。本文利用脉冲激光沉积(PLD)和射频磁控溅射(RFMS)在Ti64基底上制备了薄磷锌矿涂层。使磷锌矿涂层在500°C的真空中退火,并分别通过扫描电子显微镜(SEM)、X射线衍射(XRD)、原子力显微镜(AFM)、张力计、荧光激活细胞排序(流式细胞仪)、模拟体液(SBF)浸泡试验和接触角测角仪研究表面形态、相组成、表面粗糙度、粘附强度、抗菌功效、磷灰石形成能力和表面润湿性能。结果表明,在Ti64基底上由PLD和RFMS两种新工艺路线合成的新一代多功能磷锌矿涂层是传统涂层的有效替代品。所沉积的磷锌矿涂层具有较强的骨整合能力和抗菌特性,保证了金属骨科种植体的整体稳定性。
