nb-60ta-2zr合金在模拟血浆溶液和全血浸泡后表面膜的性质
Keywords: 生物材料,铌合金,xps,模拟血浆,血液,表面膜
Abstract:
？用x射线光电子能谱(xps)表征了心血管支架用nb-60ta-2zr合金在模拟血浆溶液(r-sbf)和在人体全血中浸泡后表面反应层的性质。结果表明,在两种介质中分别浸泡后,材料表面氧化膜的化学成分和厚度明显不同。在r-sbf溶液中浸泡24h后,在合金表面形成约50nm厚的含ca、p沉积层,覆盖于nb、ta的氧化膜之上;相反,在全血液中浸泡的合金表面未出现富ca和p的沉积层,仅形成厚度约24nm、主要由ta2o5和nb2o5构成的氧化膜。因此,尽管两种介质的离子浓度相近,但全血中的蛋白质和血细胞等有机物对ca、p等元素的沉积有抑制作用。
