| 摘 要： | 背景:在钛合金基体表面制备涂层的方法多为等离子喷涂法、溶胶-凝胶法、离子束溅射法等,所制备的涂层性能不稳定、成分单一,且涂层物相组成较难控制。目的:采用射频磁控溅射技术在Ti6Al4V基体上制备含氟羟基磷灰石梯度复合涂层HAF/YSZ。方法:在Ti6Al4V基体上以射频磁控溅射技术制备含氟羟基磷灰石梯度复合涂层HAF/YSZ,利用X射线光电子能谱、扫描电镜等对涂层的成分分布、形貌、界面结合进行表征。通过模拟体液实验分析和评价HAF/YSZ涂层、HAF1.2涂层及羟基磷灰石涂层的生物性能。结果与结论:所制备的HAF/YSZ梯度涂层表面粗糙,呈多孔岛状结构,有利于新生骨组织生长;涂层与基体结合紧密,各层间相互扩散,整体一致性较好;经模拟体液浸泡后,涂层表面有新生物质沉积,表现出较好的生物活性及稳定性,且梯度复合涂层较氟含量单一的氟羟基磷灰石涂层具有更好的抗体液溶解能力及稳定性。

| Abstract: | BACKGROUND: Plasma spraying, sol-gel coating process and ion beam sputtering are often used for making coatings on the surface of titanium alloy, but the properties of the coatings are unstable, the composition is homogeneous, and the control of the phase composition is difficult. OBJECTIVE: To prepare HAF/YSZ gradient composite coatings on Ti6Al4V substrate by radio frequency magnetron sputtering. METHODS: The HAF/YSZ gradient composite coatings were deposited on Ti6Al4V substrate by radio frequency magnet... |
