摘要:

目的       探讨激光酸蚀联合纳米管的钛表面粗化处理方法,分析其理化性能。       方法       依次采用LT-G20W光纤激光打标机轰击、18%盐酸和49%硫酸的混合物酸蚀、阳极氧化法制纳米管3个工序联合粗化光滑面的纯钛种植体表面。通过扫描电镜(SEM)观察加工完成的种植体表面形貌;应用表面电子探针(EPMA)对种植体表面的元素组成和元素化合状态进行分析;应用3D表面形貌仪在白光共聚焦扫描模式下对种植体表面粗糙度进行测试分析。       结果       成功制备复合微米、纳米结构的钛种植体表面,表面结构的元素组成为Ti、O,晶体为锐钛矿晶相,激光酸蚀联合纳米管的钛种植体表面粗糙度分别为Ra(8.38±0.91)μm、Rq(10.64±2.10)μm、Rt(43.42±6.18)μm。       结论       采用LT-G20W光纤激光打标机轰击、18%盐酸和49%硫酸的混合物酸蚀、阳极氧化法制纳米管3个工序联合粗化光滑面的纯钛种植体表面是可行的,制备的纯钛种植体表面具备优良的物理指标。

Abstract:

Objective       To study the method of laser and acid treatment of titanium implant to produce nanotubes on the surface.        Methods       The titanium surface was treated with laser, acid etching (18% HCl and 49% H2SO4) and anodic oxidation. Surface morphology was tested with scanning electron microscopy (SEM). Elemental composition and compound states were tested with electron probe microanalysis (EPMA). Surface roughness was tested with a BMT Experi 3D surface topography instrument.        Results       The surface of titanium implant had composite microstructure and nanostructure (nanotubes), element composition of Ti and O, anatase crystal phase, and surface roughness of Ra=8.19±0.09 μm, Rq=10.64±2.10 μm, and Rt=43.42±6.18 μm.        Conclusion       The surface treatment method of titanium implant with laser, acid etching (18% HCl and 49% H2SO4) and anodic oxidation generates rough surface with nanostructure and good physical properties.
