摘要: 目的 通过对常温下HF在不同时间段蚀刻Y-TZP的表面微观形态学观察来分析其提供粗化效果的能力。 方法 制作Y-TZP瓷片分别接受不处理、氧化铝喷砂、40%HF室温下酸蚀5 min、10 min、30 min、60 min、90 min、24 h后以原子力显微镜测量表面粗糙度,并以扫描电镜观察表面微观形态。 结果 氧化铝喷砂、HF酸蚀5、10 min获得的表面粗糙度接近,高于不处理者。HF酸蚀30、60、90 min和24 h获得了较高的表面粗糙度,表面呈现海绵状粗化结构形态。 结论 室温下40% HF能够对Y-TZP蚀刻获得粗化形态。

Abstract: Objective To investigate the surface roughness and surface morphology of Y-TZP etched by HF acid at room temperature. Methods Y-TZP plates were prepared and subjected to different treatments, including no treatment as control, alumina sandblasting, 40% HF acid etching for 5, 10, 30, 60, 90 min, and 24 hours. The surface roughness and microcosmic morphology were evaluated by an atomic force microscope (AFM) and a scanning electron microscope (SEM) respectively. Results HF acid etching for 5 and 10 min created similar surface roughness as alumina sandblasting did, all higher than the control. HF acid etching for 30, 60, 90 min, and 24 hours created much higher surface roughness, and presented sponge-like roughened texture. Conclusion 40% HF can etch Y-TZP and create a roughened texture at room temperature.
