摘要：

背景：制作成本较高和钛瓷结合强度薄弱使纯钛烤瓷的使用受到限制。钛黏结瓷是钛瓷系统中基本组成成分，对钛/瓷结合强度的提高起着至关重要的作用。
目的：评估自制GGW钛黏结瓷与纯钛的结合强度及性能。
方法：采用3点弯曲的测试方法分别对GGW钛黏结实验瓷与钛的结合强度以及则武黏结钛瓷与钛的结合强度进行测试，并对瓷剥脱后钛表面进行扫描电镜观察和X射线衍射分析。
结果与结论：GGW钛黏结实验瓷组的钛/瓷结合强度明显高于则武瓷组的钛/瓷结合强度(P < 0.01)。GGW钛黏结实验瓷与钛发生了化学反应，形成了大量的由平行排列的层状亚结构组成的断裂能较高的晶相组织。钛/瓷断裂发生在这些晶体结构层，断裂方式表现为沿晶与穿晶的混合形态。提示GGW钛实验黏结瓷与钛的结合强度和性能优异。

Abstract:

BACKGROUND: High production costs and weak bonding strength of titanium limit the use of titanium porcelain, in order to reduce the cost of titanium porcelain, replace nickel-chromium alloy porcelain repair, and improve security of fixed dental prosthetics. A kind of new titanium-bonding-porcelain powder GGW is produced and the properties are tested.
OBJECTIVE: To test the bond strength of new titanium-bonding-porcelain GGW to cast titanium.
METHODS: A three-point bending test was used according to ISO 9693 and SEM with energy-dispersive spectrometry analysis to evaluate the bond strength of GGW titanium bonding porcelain to cast titanium.
RESULTS AND CONCLUSION: The bond strength of new titanium-bonding-porcelain GGW to cast titanium was higher obviously than that of Super Porcelain TI-22 to cast titanium. GGW titanium experimental bonding porcelain with titanium had chemical reaction, formed by a large number of parallel arrays of layered substructure composed of fracture energy higher crystalling phase organization. Titanium/porcelain rupture occurred in these crystal structure layers, the fracture mode performance for the intergranular and wear crystal mixed form. Titanium-bonding-porcelain GGW has a promising future.
