摘　　要：目的:研究纳米非晶金刚石薄膜与纯钛及钴铬合金表面结合强度以及镀膜厚度对结合强度的影响。方法:制备钴铬合金和纯钛圆片试件各20个,将纯钛与钴铬合金试件随机分成a1、b1及a2、b2各两组。a1、a2组试件表面镀膜膜厚50nm;b1、b2组试件表面镀膜膜厚100nm。采用薄膜结合强度测试仪测试镀膜后试件的膜/基结合强度(Lc)。结果:a1、b1两组以及a2、b2两组Lc均存在显著性差异(P<0.05);膜厚相同时,纯钛和钴铬合金试件Lc之间也存在显著性差异(P<0.05)。结论:纳米非晶金刚石薄膜可以与纯钛及钴铬合金材料达到较好的结合;膜厚相同时,纳米非晶金刚石薄膜与纯钛表面的结合强度优于钴铬合金;镀膜厚度对纳米非晶金刚石薄膜与纯钛及钴铬合金的结合强度有明显影响,因此在镀膜时应选择适宜的膜厚。Objective To study the bonding strength of nanometer amorphous diamond film on the surface of dental pure Ti and Co-Cr alloys substrates and influence of the thickness of film on bonding strength. Methods We respectively prepared 20 wafers of pure Ti and Co-Cr alloys. Both the wafers of pure Ti and Co-Cr alloys were divided into two groups （a1,b1 and a2,b2） .The groups al and a2 were plated with nanometer amorphous diamond film in thickness 50nm and the groups bl and b2 were plated with the film in thickness 100nm. Finally, we used scratch test to measure the adhesion（Lc） of nanometer amorphous diamond film on pure Ti and Co-Cr alloys substrates. Results There was significant difference between the groups al and a2 on Lc, so was the difference between the groups bl and b2 as well. Moreover, in the same thickness, there was significant difference between pure Ti and Co-Cr alloys on Lc. Conclusion Nanometer amorphous diamond film can be adhered well to dental pure Ti and Co-Cr alloys substrates and its thickness will obviously influence the bonding strength,therefore, we should choose the more appropriate thickness. In the same thickness, the adhesion of nanometer amorphous diamond film on pure Ti substrate is better than Co-Cr alloys substrate.
