| 摘 要： | 为改善钛合金(Ti6Al4V)的生物相容性,采用离子束辅助沉积(Ionbeamenhanceddeposition,IBED)技术制备了氧化钛膜层。结果表明钛合金上的膜层涂覆均匀,基体的铝和钒元素已经探测不到,膜层为含氮和沿(111)面取向的TiO相;膜层划痕实验的临界载荷为16.8N,膜层以塑性变形的方式破坏。

| Abstract: | Ion beam enhanced deposition (IBED) has been applied to prepare titanium oxide layer on titanium alloy (Ti6Al4V) in order to improve its biocompatibility. The layer on titanium alloy is even, and the elements Al and V in substrate are not detected. The layer is composed of TiO containing nitrogen oriented along (111) plane. The critical load of the layer in scratch test is 16.8N. Morphological observation reveals the layer ends in a failure caused by plastic deformation. |
