摘　　要：目的观察不同沉积时间下应用等离子镀膜法镀制渗氮类金刚石碳膜(N-DLC)的颜色改变规律,以期对临床应用有所指导。方法采用等离子镀膜机在纯钛表面先沉积TiN过渡层,再沉积N-DLC碳膜,通过目测及分光光度测色法对不同沉积时间下(10～80 min,间隔5 min)N-DLC碳膜的颜色进行测定,通过CIE1976 L*a*b*及Mussell表色系统定量评价其色度属性,并结合扫描电镜观察各个沉积时段N-DLC碳膜的表面形貌。结果纯钛表面N-DLC薄膜的颜色与沉积时间有较大关系,沉积时间为30 min时得到较亮的金黄色外观;扫描电镜观察随着沉积时间增加N-DLC碳膜表面逐渐晶化,晶相结构由稳定趋于杂化。结论当镀膜沉积时间为30 min时,可在纯钛表面得到金黄色外观的N-DLC碳膜,此时的晶相结构最稳定。Objective The aim of this study was to observed the influence of deposition time on chromatics during nitrogen-doped diamond like carbon coating（N-DLC） on pure titanium by multi impulse arc plasma plating machine.Methods Applying multi impulse arc plasma plating machine to produce TiN coatings on pure titanium in nitrogen atmosphere,then filming with nitrogen-doped DLC on TiN in methane（10-80 min in every 5 min）.The colors of N-DLC were evaluated in the CIE1976 L＊a＊b＊ uniform color scale and Mussell notation.The surface morphology of every specimen was analyzed using scanning electron microscope（SEM） and X-ray photoelectron spectroscopy（XPS）.Results When changing the time of N-DLC coating deposition,N-DLC surface showed different color.Golden yellow was presented when deposition time was 30 min.SEM showed that crystallization was found in N-DLC coatings,the structure changed from stable to clutter by varying the deposition time.Conclusion The chromatics of N-DLC coatings on pure titanium could get golden yellow when deposition time was 30 min,then the crystallized structure was stable.
