摘　　要：目的:探讨磁控溅射ZrSiN/ZrO_2复合梯度涂层作为钛瓷结合中间层对钛瓷结合强度的影响。方法:将50个钛试件分为2组(n=25),实验组在钛基底表面用磁控溅射的方法制备ZrSiN/ZrO_2复合梯度涂层,对照组试件表面采用常规喷砂处理。2组试件各随机抽取10个进行粗糙度和表面能检测,各取10个用钛专用瓷粉烧结并采用三点弯曲试验进行钛瓷结合强度测试,用SEM和EDS对2组试件瓷剥脱面和钛瓷结合横截面进行观察、对比、分析。结果:ZrSiN/ZrO_2复合梯度涂层组的粗糙度低(P<0.05),接触角大(P<0.05);三点弯曲结合强度试验表明实验组钛瓷结合强度高(P<0.05);瓷剥脱面和钛瓷结合横截面的SEM和EDS分析显示,各元素原子百分比含量及线性分布情况均提示实验组试件表面瓷残留量多于对照组。结论:磁控溅射ZrSiN/ZrO_2复合梯度涂层能够控制钛金属表面过度氧化,有效缓冲钛瓷结合热应力,提升钛瓷结合强度。Objective： To evaluate the effects of magnetron-sputtered ZrSiN/ZrO2 gradient coating on the bonding strength of commercially pure titanium to porcelain. Methods ： 50 cast titanium specimens were prepared according to the ISO 9693 standard, and divided into 2 groups（ n =25 ）. The ZrSiN/ZrO2 gradient coating was deposited on specimens by magnetron sputtering technique, and subsequently a low-fusing porcelain was applied for the samples in the expermental group, the samples in the control group were treated by surface sandblasting. The roughness and surface energy of the samples were measured （n = 10）. The bonding strength of titanium- porcelain specimens was analyzed by three-point bending test（n = 10）. Scanning electron microscopy （SEM） and energy-dispersive X- ray analysis （EDS） were employed to examine the properties of the delaminated and cross-sectioned surfaces. The results were analyzed by paired t-test（ α =0.05） with SPSS 11.0 software. Results： The roughness of the experimantal group was lower（P 〈0.05） and the contact angle was larger（ P 〈 0.05 ） than those in the control group. The titanium-porcelain bond strength of gradient-coated group was greater than that of control group（P 〈 0.05 ）. The SEM and EDS examination results of delaminated and cross-sectioned surfaces also indicated that the gradient-coated group showed more porcelain residues. Conclusion： The bonding strength of porcelain-fused-to-titanium can be improved by magnetron sputtered ZrSiN/ZrO2 gradient coating.
