The surface treatment is important for titanium and its alloys as promising candidates for dental implantation due to their bioinert surface. Titanium surface samples were modified using H2O2 solution at different times up to 72 h to boost their bioactivity. According to the results of the field emission scanning electron microscopy test, some nanostructures are formed on the surface of treated titanium samples and increased in size by increasing the time of treatment up to 24 h. After 24 h of application, the sharpness of nanostructures decreased and the micro-cracks and discontinuity in the coating surface increased. The results of the X-ray diffraction study and Raman spectroscopy revealed that anatase (TiO2) was formed on the surface of treated titanium samples. The peak intensity of Raman spectroscopy increased with an improvement in treatment time of up to 24 h and then decreased due to the discontinuity of the coating. Full wettability and ability to form apatite were reached at 6 h of treatment. It is clear that the treatment time has a significant effect on the surface treatment of titanium using the H2O2 solution.

H 2 O 2溶液对钛合金种植体的表面处理

由于钛及其合金具有生物惰性表面,因此作为有希望的牙科植入物候选者,表面处理非常重要。使用H 2 O 2溶液在长达72小时的不同时间对钛表面样品进行修饰,以提高其生物活性。根据场发射扫描电子显微镜测试的结果,在处理后的钛样品表面上形成了一些纳米结构,并通过将处理时间延长至24小时而增加了尺寸。施加24小时后,纳米结构的清晰度下降,涂层表面的微裂纹和不连续性增加。X射线衍射研究和拉曼光谱的结果表明,锐钛矿(TiO 2)形成在处理过的钛样品的表面上。拉曼光谱的峰值强度随着长达24小时的处理时间的增加而增加,然后由于涂层的不连续性而降低。在处理6小时后达到了完全的润湿性和形成磷灰石的能力。显然,处理时间对使用H 2 O 2溶液对钛的表面处理有重大影响。
