【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 investigate the surface coarsening of titanium by laser etching combined with nanotubes and analyze its physical and chemical properties. Methods the mixture of 18% hydrochloric acid and 49% sulfuric acid was bombarded by LT-G20W optical fiber laser marking machine in turn. The surface of pure titanium implant was coarsened and smooth in three processes of anodic oxidation. The surface morphology of the finished implant was observed by scanning electron microscope (SEM). The surface electron probe (EPMA) was used to analyze the elemental composition and the composition of the implants. The surface roughness of the implant was measured and analyzed by 3D surface topography in the white light confocal scanning mode. Results the surface of titanium implant with composite micron and nanostructure was successfully prepared. The surface structure of titanium implants is Ra(8.38 卤0.91 渭 m RqN 10.64 卤2.10 渭 m. Conclusion the mixture of 18% hydrochloric acid and 49% sulfuric acid was bombarded by LT-G20W optical fiber laser marking machine, and the surface roughness of titanium implants was 43.42 卤6.18 渭 m. It is feasible to prepare pure titanium implant surface by anodizing process and coarsening smooth surface. The surface of pure titanium implant prepared has excellent physical index.
