| 摘 要： | 采用简单化学刻蚀法对铝合金基体进行腐蚀,得到了粗糙表面.然后对铝合金粗糙表面进行氟化处理,得到了具有超疏水的表面.研究了不同刻蚀时间以及不同刻蚀液浓度对表面疏水效果的影响.结果发现:在实验的参数条件下,不同刻蚀时间下,接触角随着氢氟酸刻蚀时间的增加,先增加后减少,当氢氟酸刻蚀时间为7 min时,所得试件水的接触角最大.不同刻蚀液浓度下,接触角随着盐酸浓度的增加,先增加后减少.当盐酸浓度为4 mol/L时,所得试件水的接触角最大.

| Abstract: | A simple chemical etching method was developed for corrosion of aluminum alloy substrate,After the chemical etched surface was treated with fluorination,the aluminum alloy surface exhibits a super-hydrophobic property,The effects of the etching time and the etchant concentration on the super-hydrophobicity were investigated,the result show the contact angle of hydrofluoric firstly increases then reduce with acid etching time increasing,and the optimum etching time is 7 min;the contact angle of hydrofluoric ... |
