摘　　要：采用热氧化法在工业纯Ti板表面构造微/纳双尺度粗糙结构,并利用自组装技术制备超疏水Ti表面(TO-FOTS),对其耐蚀性能进行研究。结果表明,TO-OTS对全p H值的腐蚀液均具有良好的超疏性,静态接触角为155°左右。同时,TO-OTS具有十分稳定的气/液/固三相界面,可以有效阻止氢氟酸对金属基底的侵蚀。The super hydrophobic coating on the metal titanium plate was prepared by thermal oxidation process and self-assembly, and the anti-corrosion was studied. The results show that the TO-FOTS has an excellent super hydrophobic property to the corrosive liquid, and the static contact angle is around 155° . At the same time, the TO-FOTS has a stable gas/liquid/solid three phase interface, which can effectively prevent the metal matrix to hydrofluoric acid erosion.
