摘要：

目的探讨镍铬烤瓷合金中添加钛（Ti）、稀土金属以及不含铍（Be）对金瓷结合性能的影响。方法选用中国科学院金属研究所研制的镍铬烤瓷合金，按照是否含铍和稀土金属分为3个实验组（R1、R2、R3组）；以HI BONDNi-Cr烤瓷合金作为对照组（R4组）。对金瓷结合试件行剪切结合强度测试和金瓷界面的扫描电镜观察与能谱分析。结果R1、R2、R3、R4组剪切结合强度间差异无统计学意义（P＞0.05）。扫描电镜观察金瓷界面形貌可见，合金与瓷紧密接触，无裂缝。各组界面元素种类接近。结论自制镍铬烤瓷合金的金瓷结合良好，剪切结合强度可以达到临床应用的要求。在镍铬烤瓷合金中加入Ti和稀土金属且不含Be可作为临床使用的更好推荐。

Abstract:

Objective To study the bonding capability when Ni-Cr porcelain alloy was added with Ti, compound rare earth metals and removed the element of Be. Methods Ni-Cr-Ti porcelain alloys manufactured by Institute of Metal Research of Chinese Academy of Sciences were tested. The test alloys were divided into three groups according to whether containing Be and compound rare earth metals or not. And HI BOND Ni-Cr base-metal alloy was chosen as control. The metal-ceramic specimens were prepared for shear test, scanning electron microscope（SEM） and energy spectrum analysis. Results The shear bond strength of the four groups were analyzed. No significant difference were observed among them（P ＞0.05）. No crackle was found and they were contacted tightly between the porcelain and metal. The composition and contents of the four groups′ interfaces were closed. Conclusion The shear bond strength of the self-made Ni-Cr-Ti porcelain alloys all can satisfy the clinical requirements. Experimental groups containing Ti, compound rare earth metals and removing the element of Be can be used as better recommendation for clinical practice.

Key words: ceramic, Ni-Cralloy, Ti, shearbondstrength, metal-porcelaininterface
