The surfaces of titanium (Ti–6Al–4V) implants, which are widely preferred as implant material in medicine and dentistry, are biomimetically coated with nanohydroxyapatite (nHAp) in simulated body fluid (10XSBF) with microwave-assisted 10-f time concentration solution. A second layer was formed with different amounts of non-toxic AgNO3 to impart antibacterial properties to the implant materials coated with nHAp. In comparison of uncoated implants with nHAp and Ag-coated Ti–6Al–4V implants, surface morphologies were evaluated by SEM analysis, phase grade and structure were evaluated by XRD, and surface properties were evaluated by XPS, AFM and mapping analysis. It was observed that the surface changed after Ag coating and had the appearance of cauliflower. With this study, an amorphous surface was created for Ti-6-Al-4V implants in a short time in the domestic microwave. In addition, their surfaces were coated with silver. Implants with antibacterial properties showed resistance to bacteria.

Ti-6Al-4V 10XSBF 类骨羟基磷灰石涂层的微波辐射及其抗菌性能

钛 (Ti–6Al–4V) 植入物的表面在模拟体液 (10XSBF) 和微波辅助 10-f 时间浓缩溶液中仿生地涂有纳米羟基磷灰石 (nHAp),在医学和牙科中广泛用作植入材料. 第二层由不同量的无毒 AgNO 3形成赋予涂有 nHAp 的植入材料抗菌性能。比较具有 nHAp 和 Ag 涂层的 Ti-6Al-4V 植入物的未涂层植入物,通过 SEM 分析评估表面形态,通过 XRD 评估相等级和结构,通过 XPS、AFM 和映射分析评估表面特性。观察到表面在镀银后发生变化并具有花椰菜的外观。通过这项研究,在家用微波炉中短时间内为 Ti-6-Al-4V 植入物创建了非晶表面。此外,它们的表面涂有银。具有抗菌特性的植入物显示出对细菌的抵抗力。
