Nowadays, the practical application of the super-hydrophobic surfaces is limited by their mechanical durability. In this work, robust super-hydrophobic cobalt-nickel coatings reinforced by micro-nano tungsten carbide (WC) particles were achieved on carbon steel substrate by electrochemical deposition from the mixed solution. The effect of WC particles content on the surface morphology, wetting properties and the corrosion protection performance of the composite coatings were investigated. The linear abrasion test indicated that the as-prepared super-hydrophobic CoNi/WC composite coating with 9.8 wt% WC content, displayed excellent wear resistance with super-hydrophobic property for abrasion distance up to 34 m. Furthermore, the super-hydrophobic CoNi/WC coating with robust mechanical durability can be a promising alternative technique for corrosion protection.

如今，超疏水表面的实际应用受到其机械耐久性的限制。在这项工作中，通过从混合溶液中电化学沉积，在碳钢基材上获得了由微纳碳化钨（WC）颗粒增强的坚固的超疏水钴镍涂层。研究了WC颗粒含量对复合涂层表面形貌，润湿性能和防腐性能的影响。线性磨损试验表明，所制得的WC含量为9.8 wt％的超疏水Co Ni / WC复合涂层显示出优异的耐磨性，且超耐磨性适用于长达34 m的磨损距离。此外，超疏水Co具有强大机械耐久性的Ni / WC涂层可以成为一种有前途的防腐技术。
