摘要:

为掌握机械瓣膜衬底温度对类金刚石薄膜的影响规律,在实验中保持其它实验参数不变,机械瓣膜衬底温度分别取室温和150℃时,用脉冲激光沉积法在机械瓣膜上制备类金刚石薄膜。用Raman光谱仪对薄膜的微观结构进行检测;用原子力显微镜对薄膜的表面形貌和粗糙度进行检测。结果表明:当其它实验参数不变时,机械瓣膜衬底温度从室温升高到150℃时,薄膜的微观结构没有发生明显改变;薄膜表面的粗糙度减小。类金刚石薄膜和机械瓣膜衬底之间具有很好的黏附性。

Abstract:

In order to find out the rule for temperature of mechanical heart valves to influence diamond like carbon (DLC) film, the diamond like carbon films were deposited on mechanical heart valves by the pulsed laser deposition while the temperature of the mechanical heart valve kept chamber temperature and 150℃ respectively and other experimental conditions were kept unchangeable. The microstructure of the film was detected by the visible Raman spectroscopy. The topography and roughness of the film were detected by the atomic force microscopy (AFM). The experimental result demonstrates when the temperature of the mechanical heart valve increases from chamber temperature to 150℃, change of the film microstructure would not be obvious. The roughness of film surface would reduce. The diamond like carbon film would exhibit strong adhesion to mechanical heart valve.

Key words: materials, diamond like carbon film, pulsed laser deposition, substrate temperature, microstructure, topography
