Preparation of biomimetic superhydrophobic coating on mild steel
Journal Title: Journal of Achievements in Materials and Manufacturing Engineering - Year 2016, Vol 74, Issue 1
Abstract
Purpose: Superhydrophobic surface has many special functions and is widely investigatedby researchers. Mild steel is one among the practice metals and plays an importantrole in all industrial applications. In this work, a simple method was used to generatesuperhydrophobic sueface on steel plates by electroless deposition of zinc followed byelectrochemical deposition of stearic acid.Design/methodology/approach: Scanning electron microscope (SEM) and Contactangle Goniometer were used for characterize the coated sample.Findings: The fabricated surfaces were stable against acidic solutions was evident fromthe weight loss studies. Given their strong water repulsive properties, superhydrophobiccoatings are an ideal candidate for slowing down corrosion of the metal layer.Practical implications: These results will aid in the conclusion of coating done on thespecimen and also show that the as-prepared superhydrophobic surface has obvious anticorrosioneffect in typically corrosive solution and naturally humid air. The approach is timesavingand cheap, and it is supposed to have a promising future in industrial fields.
