| 摘 要： | 类金刚石(DLC)薄膜与不锈钢的结合强度是DLC薄膜应用于血管支架表面改性的关键技术问题.利用磁过滤阴极真空弧源沉积方法在316L不锈钢表面沉积DLC薄膜,研究沉积时基体偏压、薄膜厚度以及钛过渡层对DLC薄膜与基体结合强度的影响.研究结果表明,316L表面制备相同厚度的DLC薄膜,采用-1000V脉冲偏压制备的薄膜结合强度明显优于-80V直流偏压下制备的DLC薄膜;随着DLC薄膜厚度的增大,DLC薄膜与316L基体的结合力下降;316L不锈钢表面制备一层100nm的钛过渡层之后可以改善DLC薄膜的结合状况,并且经过20%的拉伸变形后,DLC薄膜完整,耐蚀性优于未表面处理的316L不锈钢.以上研究结果表明,磁过滤阴极真空弧源方法制备DLC薄膜与316L结合强度高,可以有效的提高316L的耐腐蚀性,是一种具有应用前景的血管支架表面改性方法.

| Abstract: | Increasing the adhesion between DLC films and stainless steel substrates was the significant technical factor of Diamond-like carbon (DLC) films applying to vascular stent surface modification. In this paper, DLC films were deposited on the 316L stainless steel substrates by filtered cathodic vacuum arc (FCVA) deposition. The effect of deposition process, such as bias voltage, films thickness and titanium transition layer, on interfacial adhesion was studied. The results indicate that the adhesion of the DL... |
