深海集矿车履齿自清洁及稳定性研究

Study on Self-Cleaning and Stablility of Deep Sea Collector Teeth

摘要:

针对集矿车海底行走履带粘泥严重的情况，基于超疏水材料良好的自清洁特性，通过化学刻蚀法和PFDS乙醇溶液修饰工艺制备具有优良自清洁效果的集矿车履齿。对制备的履齿样品进行表面结构和形态表征，评价了其超疏水表面层的自清洁、耐摩擦、耐酸碱等服役性能。结果表明，表面处理后的样品接触角最高达154 °，其具有优良的自清洁特性，且耐磨性和抗酸性腐蚀效果良好。

Abstract:

In view of the serious situation of sticky mud on the submarine walking track of the collector car， based on the good self-cleaning effect of superhydrophobic materials， it is proposed to prepare the mining truck track teeth with excellent self-cleaning effect by chemical etching method and PFDS ethanol solution modification. Surface characterization of the prepared crawler tooth samples was carried out， and the self-cleaning properties， friction resistance， acid and alkali resistance were studied. The results show that the contact angle of the samples after surface treatment is up to 154 °， which has excellent self-cleaning performance， and good wear resistance and acid corrosion resistance.
