摘要/Abstract

摘要： 目的对比钛表面分别经微弧氧化和Nd:YAG激光处理、喷砂处理后的表面形貌、理化性能的差异，比较其对钛瓷结合强度的影响。方法将60个规格为25.0 mm ×5.0 mm ×0. 5 mm的标准钛片试件，随机均分为3组，每组20片(A 组为微弧氧化组，B组为激光轰击组,C组为喷砂组),运用扫描电镜、X射线衍射仪、EDS等分析其形貌和物相；三点弯曲实验测试钛瓷结合强度并进行统计学分析比较。结果 A、B、C 3组试件的钛瓷结合强度均高于ISO9693要求的25 MPa，Nd:YAG激光处理试件钛瓷结合强度较微弧氧化处理高，且两者均高于喷砂组。结论 3种处理方式都能提高钛表面的钛瓷结合强度，Nd:YAG激光处理后效果优于微弧氧化和喷砂处理。

Abstract: Objective To investigate the effects of micro arc oxidation, Nd:YAG laser-treatment and sandblasted on titanium-ceramic bonding. The surface morphology, physical properties and bonding strength were compared. Methods 60 pieces of titanium sheet of 25.0 mm ×5.0 mm ×0.5 mm were randomly divided into 3 groups, each group of 20 pieces. The A group was treated by micro arc oxidation, the B group was treated with laser, and the C group was treated by sandblasted. Scanning electron microscope (SEM), X ray diffraction (XRD), Energy Dispersive Spectroscopy (EDS) and other instruments were used to analyze the chemical composition and the surface topography. Three point bending test was conducted to measure the bonding strength, and the results were analyzed statistically. Results Bonding strength of group A, B and C were all higher than the minimum requirement (25 MPa) of ISO 9693. The bond strength of group B was higher than of group A, both of which were higher than group C. Conclusion All treatment methods can improve the titanium-porcelain bonding strength, and the effect of Nd:YAG laser treatment is the best.

Key words: Nd:YAG laser, Titanium, Bond strengths of titanium to porcelain, 3-point bending test method
