摘　　要：目的:探讨在纯钛表面液相沉积法制备SiO2中间层对钛瓷结合强度的影响。方法:将40个纯钛试件平均分为4组(n=10),喷砂后A、B组用液相沉积法在试件表面制备SiO2中间层,C、D组不作表面处理,测各组试件的表面粗糙度。参照IS0 9693(1999)Amd.1 2005(E)标准在A、C组试件中份烧结Duceratin瓷粉,在B、D组试件中份烧结Ti-22瓷粉,测各组试件钛瓷间的三点弯曲结合强度,并对钛瓷结合界面进行扫描电镜观察。结果:各组试件表面粗糙度差异无显著性,A、B组钛瓷结合强度高于C、D组,其差异有显著性(P<0.05),A、B组之间及C、D组之间钛瓷结合强度差异无显著性。扫描电镜观察显示各组试件钛瓷结合界面均未见明显氧化层。结论:通过液相沉积法在纯钛表面制备SiO2中间层可提高Duceratin及Ti-22两种常用钛瓷粉的钛瓷结合强度。Objective： To investigate the effect of middle layer by liquid-phase deposition（LPD） technology on bonding strength of titanium and porcelain.Methods： Forty pure titanium specimens were randomly divided into four groups（n=10）according to different surface treatments after sandblasting： group A（middle layer-Duceratin）,group B（middle layer-Ti-22）,group C（Duceratin）,group D（Ti-22）.We measured the roughness of each group.After the middle area of the specimens were veneered with porcelain,a three-point-flexure-test was used to evaluate the bonding strength of titanium to porcelain.The interface of titanium and porcelain was investigated by scanning electron microscope（SEM）.Results： There were no significant differences in the roughness among four groups.The bonding strength of groups A and B were significantly higher than those of groups C and D（P＆lt;0.05）,and there were no significant differences in the bonding strength between groups A and B,C and D.No definite oxide layer was observed at the interfaces in four groups.Conclusion： Middle layer prepared by LPD technology was significant in improving bonding strength of two different porcelain and pure titanium.
