Abstract
諸多研究顯示,鈦基金屬及其合金於人體的生物相容性(biocompatibility)有極高的評價,其非常適合做為人體的植入物,然而鈦金屬及其合金之所以具極佳的生物相容性主要是與鈦金屬表面的氧化層有關,研究指出植體表面氧化層厚度與孔徑大小對於細胞初始的攀附行為、增殖及分化有密切的關係。若能有效增加氧化層厚度與降低植體表面孔徑尺寸將對骨整合會有所助益。於文獻指出氫化鈦是形成網狀奈米多孔性氧化層結構主要因子,並且能有效增加氧化層厚度。因此,本研究以電化學陰極處理方式使鈦基金屬表層形成一層氫化鈦(TiH2)薄膜,再以電化學陽極處理,使表面形成一層網狀奈米多孔性的二氧化鈦(TiO2)結構,並以一些物理及化學性的分析儀器測試表面之成分、元素、膜厚、孔洞大小及結構,進一步進行細胞實驗並探討網狀奈米多孔性的二氧化鈦的形成機制。
