| 摘 要： | 铜丝可用于尿毒症患者腹膜透析置管术中的替代导丝。为了减少或消除铜离子对生物组织的损害,增加铜丝表面的生物相容性,同时又保持铜丝较好的塑性变形能力,本文采用电弧离子镀工艺在铜丝上沉积Ti/TiN多层膜。研究结果显示,镀膜铜丝表面光亮呈金黄色。沉积膜有明显的周期性层状特征,TiN相和金属Ti相周期性交替分布。其中,TiN相具有(111)晶面择优取向。沉积膜与铜丝结合良好,弯曲时镀膜铜丝没有出现微裂纹和膜脱落现象。室温消毒液浸泡和高温蒸汽消毒处理后,镀膜铜丝表面没有变化。腹膜透析置管术中使用镀膜铜丝,患者腹膜炎发生率明显降低,镀制Ti/TiN多层膜的铜丝适合应用于腹膜透析手术。 |

| Abstract: | Ti/TiN multilayer films were deposited on Cu filament by arc ion plating to investigate its possibility to be used for inserting peritoneal catheters in continuous ambulatory peritoneal dialysis.Results show that the deposited Ti/TiN films have gold color with smooth surface.The films possess an obvious periodically laminated characteristic with alternately distributed TiN phase and Ti phase and the TiN phase shows(111) preferred orientation.It is indicated that the films have high adhesive force to Cu fila... |
| Keywords: | Ti/TiN multilayer film biocompatibility laminated characteristic adhesive force toughness |
