Fabrication of TiO2-Ag composite coating and its capability

摘要:

为在钛合金表面制备得到既具有生物活性，又具有抗菌性能的涂层材料，本文利用扫描电子显微镜、X射线衍射仪、生物活性实验、抗菌性实验等设备和方法，系统的研究了热处理方法对氧化钛银复合涂层的形成及性能的影响。研究表明在钛片表面制备氧化钛纳米管阵列后，于500癈或600癈条件下，对浸泡了硝酸银饱和溶液的氧化钛纳米管阵列进行热处理，能够在钛合金表面制备得到即具有生物活性又具有抗菌性的氧化钛银复合涂层。

Abstract:

An experimental set-up was designed for the fabrication of composite coating containg titania and Ag on the surface of titanium and make the titanium has bioactive and antibacterial synchronously. The SEM, XRD, bioactive test and antibacterial test were imployed to researched that how the method of the heat treatment work on the formation and capability of the titania-Ag composite coating. The results show that titanium with titania nanotube arrays diped in the saturated silver nitrate solution and heated under 500癈 or 600癈, the titanium can obtain bioactive and antibacterial synchronously because of the existence of titania-Ag composite coating.
