【摘要】：目的改善金屬鋅在海洋環(huán)境中的耐蝕及摩擦學(xué)性能。方法通過簡(jiǎn)單的化學(xué)刻蝕及自組裝技術(shù)在金屬鋅表面制備超疏水薄膜,對(duì)薄膜的結(jié)構(gòu)和潤(rùn)濕性進(jìn)行了表征,研究了超疏水薄膜在模擬海水(3.5%Na Cl溶液)中的耐蝕性能和摩擦學(xué)性能。結(jié)果經(jīng)N,N-二甲基甲酰胺水溶液刻蝕后,金屬鋅表面呈多尺度微納的Zn O結(jié)構(gòu),Zn O結(jié)構(gòu)經(jīng)硬脂酸修飾后,表面呈現(xiàn)出超疏水特性,表面靜態(tài)接觸角達(dá)150°,滑動(dòng)角小于5°。同時(shí)發(fā)現(xiàn),在3.5%Na Cl水溶液中,金屬鋅表面超疏水薄膜具有優(yōu)異的耐蝕性能,并能夠顯著降低摩擦和磨損。結(jié)論經(jīng)簡(jiǎn)單的化學(xué)刻蝕及自組裝技術(shù)可在鋅表面構(gòu)筑超疏水薄膜,薄膜在海洋環(huán)境下具有良好的耐蝕、減摩及耐磨性能。
[Abstract]:Aim to improve the corrosion resistance and tribological properties of metallic zinc in marine environment. Methods Superhydrophobic thin films were prepared on the surface of zinc by simple chemical etching and self-assembly techniques. The structure and wettability of the films were characterized. The corrosion resistance and tribological properties of superhydrophobic films in simulated seawater 3.5% NaCl solution were studied. Results after etching with NN- dimethylformamide solution, the Zn O structure on the surface of zinc was modified by stearic acid. The surface shows superhydrophobic properties, the static contact angle is 150 擄and the sliding angle is less than 5 擄. It is also found that the ultrahydrophobic film on the surface of zinc has excellent corrosion resistance in 3.5 NaCl aqueous solution. Conclusion Superhydrophobic thin films can be prepared on zinc surface by simple chemical etching and self-assembly techniques. The films have good corrosion resistance, antifriction and wear resistance in marine environment.
