摘　　要：目的:研究纯钛铸件镀制TiN薄膜对提高钛与聚合瓷结合强度的可行性。方法:铸造纯钛试件12片,随机分为2组,一组表面常规处理,另一组表面镀制TiN薄膜,分别与Ceramage聚合瓷粘接。运用平行界面剪切法测试钛-聚合瓷的结合强度,并在扫描电镜下观察钛-聚合瓷结合界面的形貌。采用SPSS11.0软件包进行两样本t检验。结果:TiN镀膜组结合强度为(29.78±0.78)MPa,高于常规处理组结合强度(25.73±0.37)MPa,有显著性差异(P<0.01),两者均大于ISO9693:1999标准所要求的基本值25MPa(P<0.01)。结论:TiN镀膜可以有效提高钛-聚合瓷的结合强度。PURPOSE： To investigate the feasibility of increasing bond strength of polymer ceramic to titanium using TiN coating. METHODS： Twelve pure titanium specimens were casted and divided into two groups randomly. In one group, the surface was processed with conventional handling,in the other group,the surface was coated with TiN. Then the specimens in each group was bonded with polymer ceramic material （Ceramage）. The shear bond strength was measured using parallel interface shearing. The interface between polymer ceramic and titanium was observed under SEM. Two samples t test was conducted with SPSS11.0 software package. RESULTS： The shear bond strength of TiN plating coat group was （29.78±0.78）MPa,larger than that of the conventional handling group （25.73±0.37）MPa, the difference was significant （P〈0.01） between the two groups, and both of them exceeded ISO9693：1999（P〈0.01 ）. CONCLUSION： TiN plating coat can effectively improve the shear bond strength. Supported by National Natural Science Foundation of China （Grant No.30171022）.
