摘要： 目的 探讨2种酸液热酸蚀对氧化锆表面形貌和粘接强度的影响。方法 制备10 mm×10 mm×2 mm的氧化锆试件（Ⅰ类）24个,3 mm×3 mm×2 mm的试件（Ⅱ类）20个,将其平均分为4组进行处理,即空白对照组（A组）、喷砂处理组（B组）、HCl热酸蚀组（C组）以及HF热酸蚀组（D组）。采用原子力显微镜（atomic force microscopy, AFM）、扫描电镜（scanning electron microscope, SEM）、X射线衍射仪（X-ray diffraction, XRD）和万能试验机等对氧化锆表面形貌及粘接强度进行观察和检测。采用SPSS 26.0 软件包对实验数据进行单因素方差分析和最小显著性差异检验,XRD的检测结果采用MDI Jade 6 软件和Origin 2019 软件进行处理。结果 C组和D组的形貌图像与B组截然不同,B组可见明显的粘接界面裂隙,D组具有最大的粗糙度（78.17±4.94） nm 及最大的剪切粘接强度（25.09±4.09） MPa。结论 与HCl相比,HF热酸蚀能使氧化锆形成更加均匀致密的多孔形貌,粗糙度和粘接强度也更大,不会造成明显的粘接界面裂隙及晶相转变。

Abstract: PURPOSE: This study evaluated the effect of hot etching with two acid solutions on the surface topography and bond strength of zirconia. METHODS: Firstly, twenty-four pieces of zirconia with a size of 10 mm×10 mm×2 mm and 20 pieces of zirconia with a size of 3 mm×3 mm×2 mm were prepared. Then pieces were divided into four groups, and dealt with separately according to the following groups: no treatment (group A), sandblasting (group B), hot etching with HCl(group C), hot etching with HF(group D). Finally, the surface topography and bond strength were tested by atomic force microscopy(AFM), scanning electron microscope(SEM), X-ray diffraction(XRD) and universal testing machine, etc. Statistical analysis of the experimental data was performed with SPSS 26.0 software package. The final results of XRD were analyzed using MDI Jade 6 combined with Origin 2019 software. RESULTS: Groups C and D produced completely different topographical changes on the surface of zirconia than group B. Obvious interfacial cracks were observed in group B. Group D achieved the highest roughness value (78.17±4.94) nm and highest shear bond strength (25.09±4.09) MPa. CONCLUSIONS: Compared with HCl, hot etching with HF could achieve more uniform and dense porous morphology, greater roughness and shear bond strength. There were no obvious cross-section interfacial cracks and crystal phase transformations on the surface of zirconia.
