本研究的目的是评估钛与瓷的剪切结合强度以及表面处理对钛表面结构的影响。在剪切结合强度测试中，钛表面处理为：常规、无粘结剂的二氧化硅涂层和有粘结剂的二氧化硅涂层。用于通过原子力显微镜（AFM）分析的钛表面处理是：抛光、氧化铝喷砂和二氧化硅涂层。硅涂层加粘结剂组的剪切粘结强度值显著高于其他组。在AFM观察结果中，仅在二氧化硅涂层中观察到规则的泡沫结构，这是有效的润湿。因此，该结构可能指示硅。二氧化硅涂层使钛表面形成纳米级规则的泡沫结构，具有超亲水性，这与氧化铝喷砂产生的不规则表面明显不同。
The aim of this study was to evaluate the shear bond strength of porcelain fusing to titanium and the effects of surface treatment on surface structure of titanium. In the shear bond strength test, titanium surface treatments were: conventional, silica-coating without bonding agent, and silica-coating with bonding agent. Titanium surface treatments for analysis by the atomic force microscope (AFM) were: polishing, alumina sandblasting and silica-coating. The shear bond strength value of silica-coating with bonding agent group showed significantly higher than that of other groups. In AFM observation results, regular foamy structure which is effective for wetting was only observed in silica-coating. Therefore, this structure might indicate silicon. Silica-coating renders forms a nanoscopic regular foamy structure, involved in superhydrophilicity, to titanium surface, which is markedly different from the irregular surface generated by alumina sandblasting.
