采用等离子镀膜机,在纯钛试件表面沉积N-DLC薄膜、TiN薄膜、阳极氧化膜以及空白对照,然后将其黏附于树脂基托表面,实际使用6个月后,扫描电子显微镜观察白色假丝酵母菌黏附试件情况;粗糙度检测仪对比检测试件粗糙度变化。结果:白色假丝酵母菌在N-DLC膜表面附着数量比其他组试件明显少(P<0.05),且菌体生长不良,处于抑制状态;阳极氧化膜和空白对照试件表面黏附菌量最多,且菌体生长旺盛。
N-DLC film, TiN film, anodic oxide film and blank control were deposited on the surface of pure titanium by plasma coating machine, and then adhered to the surface of the resin base. After 6 months in actual use, the white fake Candida sticky specimen conditions; Roughness detector contrast test specimen roughness changes. Results: The number of Candida albicans attached to N-DLC membrane surface was significantly less than that of other samples (P <0.05), and the cell growth was poor and in a state of inhibition. The amount of adherent bacteria on the surface of anodic oxidation membrane and blank control Most, and strong cell growth.
