摘要：

背景：氮化钛涂层与黏结瓷均可改善钛瓷结合强度。
目的：观察氮化钛涂层和Noritake Ti-22黏结瓷对钛瓷结合强度的影响。
方法：将32个纯钛铸件表面喷砂后分为4组：纯钛组、氮化钛涂层组、黏结瓷涂布组、氮化钛涂层联合黏结瓷涂布组。将处理后各组试件中间部分烤瓷，运用三点弯曲方法测试各组金瓷结合强度。
结果与结论：纯钛组钛瓷结合力低于氮化钛涂层组、黏结瓷涂布组、氮化钛涂层联合黏结瓷涂布组(P < 0.05)，后3组组间结合强度差异无显著性意义(P > 0.05)。氮化钛涂层组、黏结瓷涂布组、氮化钛涂层联合黏结瓷涂布组钛瓷界面结合紧密，无明显孔隙和气泡；纯钛组钛瓷结合界面有明显孔隙。说明氮化钛涂层和黏结瓷的应用有利于提高钛瓷结合强度，单两种处理方法同时作用并不能更好地提高钛瓷结合强度。

Abstract:

BACKGROUND: Titanium nitride (TiN) coating and bond porcelain can improve the bonding strength of titanium porcelain.
OBJECTIVE: To investigate the influence of TiN and bond porcelain on the bonding strength of titanium porcelain．
METHODS: Totally 32 cast pure Ti plates were prepared. After sandblasting, the cast plates were divided into four groups: A, B, C and D groups. A: pure Ti group, B: TiN coating group, C: bond porcelain coating group, D: TiN+bond porcelain coating group. And then porcelain was baked at the center of the plates. All plates were submitted to a three-point bending test.
RESULTS AND CONCLUSION: The titanium-porcelain binding stength of the group A was lower than that of the groups B, C and D (P < 0.05).There were no significant differences in the bonding strength among the groups B, C and D (P > 0.05). Titanium porcelain interfaces of groups B, C and D were linked closely together, and there were no obvious pores and bubbles. These findings suggest that the application of the TiN and bond porcelain is helpful to improve the bonding strength of titanium porcelain. If they are handled in two ways simultaneously, the bonding strength of titanium porcelain cannot be improved better.
