中文摘要 | 本研究使用生醫材料Ti-6Al-4V合金為基材,利用電化學方法電解沉積氧化鋯陶 瓷薄膜。經燒結處理後再以恆定電位儀、SEM、XRD、OM、刮痕試驗機等儀器觀察分析氧化鋯 薄膜的性質。 循環極化實驗,發現未處理試片與具氧化鋯薄膜塗層的 Ti-6Al-4V 合金,實 際上並不參與反應,試片亦無腐蝕之發生。在 NaC1 溶液中實際上只以下幾個反應發生: (1)O��+2H�烙+4e���i4OH��;(2)2H��+ 2e���iH��;(3)2H�烙+2e���iH��+2OH�牷C 此外,具氧化鋯 薄膜塗層的試片,其 EO�站�未處理試片高,因未處理試片較容易吸附 OH,而通氮氣會降低 EO�砥C 經由刮痕試驗可發現,在 0~30N 的荷重下,並未有氧化鋯脫落的現象。顯示,鍍膜 在 Ti-6Al-4V 合金之附著力能克服 1700Mpa 之荷重應力,而此應力是一般人體運動中髖骨 荷重之 50 倍,使用在生醫植入材中可避免與超高分子量聚乙烯( UHMWPE )間之磨耗,增 加使用年限,減少病人手術的次數。 |
英文摘要 | In this research, Ti-6Al-4V alloy was selected as the substrate and electrolytically deposited with ZrO�疳n an aqueous solution of zirconyl nitrate (ZrO(NO�� �K )2). Through the Polarization test, scanning electron microscopy (SEM), Xray diffractometry (XRD), optical microscopy (OM), and scratch test, the characteristics of the thin film were analyzed. In the cyclic polarization experiments, both the as-received specimens and the coated specimens were not corroded actually. Three reactions were found in 0.6M NaCl aqueous solution:(1) O��+2H�烙+4e�i4OH��;(2)2H��+ 2e���iH��;(3)2H�烙+2e�iH��+2OH��. Additionally, the specimens coated with ZrO�病ilm had higher EO��(the upper redox equilibrium potential) than the as-received specimens because the latter had stronger tendency to attract the OH, and the E �K would be reduced if the solution was deaerated by pure N2. The scratch test showed no peeling of ZO�病orm the substrate under the load of 30 Newtons. This indicates that the adhesion of Zr O�畚oating on Ti-6Al-4V alloy substrate can resist the loading stress of 1700 MPa which is 50 times of the loading of hip joints during gait. When ZrO�疳s used as the implant material, it can reduce the wear debris with the UHMWPE and enhance its endurance. |
