摘要
目的:研究纯钛铸件镀制纳米渗氮类金刚石碳膜(N-DLC)在体外球磨实验及刷洗实验中粗糙度、表面形貌变化,为临床应用类金刚石碳膜提供理论依据。方法:铸造纯钛试件30片,分别镀制N-DLC、TiN薄膜以及空白对照后进行球磨实验和牙刷刷洗实验,通过测量摩擦系数及磨痕深度等综合评价其耐磨性,并在扫描电镜下观察表面形貌。结果:3组试件中,N-DLC镀膜的粗糙度增加值、反射率下降值最小(P﹤0.01),空白对照组的变化最大(P﹤0.01),TiN的变化值略小于N-DLC镀膜(P﹤0.05)。扫描电镜观察空白对照表面刷痕明显,TiN和N-DLC镀膜表面未见明显刷痕,仅见有加工处理残留的细小痕迹。结论:与其他表面改性方法相比,N-DLC镀膜的表面形态受磨耗试验影响最小。
Objective： To evaluate the roughness and surface morphology of pure titanium coating with Nitrogen-diamond like carbon（N-DLC） after ball milling experiments and in vitro tooth-brushing,for the clinical application of N-DLC to provide a theoretical basis.Methods： 30 specimens of pure titanium casting were deposited on N-DLC,TiN film and contrast group after ball milling and tooth-brushing,by measuring the friction coefficient and wear track depth evaluation of its wear resistance,and scanning electron microscope to observe the surface morphology.Results： The specimens in the three groups,N-DLC coating roughness value,minimum value of reflectance decrease（P0.01）,the greatest change in the control group（P0.01）,TiN changes in the value of slightly less than N-DLC coating（P0.05）.Scanning electron microscope was the control surface brush marks,TiN,and N-DLC coating surface had no obvious brush marks,only saw a small residual traces of processing.Conclusion： Compared with other surface modification methods,the effect of brushing test for N-DLC coating on the surface morphology is the smallest.
