Abstract

Biomedical Ti6Al4V Eli alloy discs were subjected to blasting, anodisation and ultra viola (UV) treatments under the same manufacturing conditions with implants. These different surface modification effects on topography and wetting performance were investigated in detail with optical tensiometer for autoclaved and non-autoclaved samples. Surface contact angle changes after packing of the surfaces were investigated for initial, 1 and 3 months later. The topographical investigation by scanning electron microscope (SEM) showed that blasted 350 V had the mean 1.842 ± 102 nm pores size and blasted 280 V treated surfaces had the mean 771 ± 85 nm pore size. Autoclaving decreased wettability capabilities of all surfaces, especially for the blasted specimen group. According to the repetitive measurement results, after the 1st month the wettability's of the surfaces were similar compared to the initial. After the 3rd month, a decreasing trend was observed for wetting capability. But beyond all groups, the contact angle was the same with non-UV treated state for the blasted 350 V group after 3rd month.

研究紫外线处理和表面改性对生物医学表面表面能和老化行为的影响

生物医学Ti6Al4V Eli合金盘在与植入物相同的制造条件下进行了爆破、阳极氧化和紫外线处理。利用光学张力计对蒸压和非蒸压样品的表面改性对形貌和润湿性能的影响进行了详细的研究。在初始、1个月和3个月后对表面包装后的表面接触角变化进行了研究。扫描电镜(SEM)形貌分析表明，350 V喷砂处理表面的平均孔径为1.842±102 nm, 280 V喷砂处理表面的平均孔径为771±85 nm。高压灭菌降低了所有表面的润湿性，特别是对被炸试样组。根据重复测量结果，第1个月后，表面的润湿性与初始相似。第3个月后，润湿能力呈下降趋势。但在3个月后，350 V喷砂组的接触角与未uv处理状态相同。
