功能化種植體展示了骨科種植體的升級(jí)方法,旨在通過改進(jìn)生物整合實(shí)現(xiàn)長期成功。多功能的生物陶瓷涂層由于其結(jié)合了生物植入物所必需的各種性能,如骨整合和抗菌特性,已成為傳統(tǒng)涂層的有效替代品。本文利用脈沖激光沉積(PLD)和射頻磁控濺射(RFMS)在Ti64基底上制備了薄磷鋅礦涂層。使磷鋅礦涂層在500°C的真空中退火,并分別通過掃描電子顯微鏡(SEM)、X射線衍射(XRD)、原子力顯微鏡(AFM)、張力計(jì)、熒光激活細(xì)胞排序(流式細(xì)胞儀)、模擬體液(SBF)浸泡試驗(yàn)和接觸角測角儀研究表面形態(tài)、相組成、表面粗糙度、粘附強(qiáng)度、抗菌功效、磷灰石形成能力和表面潤濕性能。結(jié)果表明,在Ti64基底上由PLD和RFMS兩種新工藝路線合成的新一代多功能磷鋅礦涂層是傳統(tǒng)涂層的有效替代品。所沉積的磷鋅礦涂層具有較強(qiáng)的骨整合能力和抗菌特性,保證了金屬骨科種植體的整體穩(wěn)定性。
