Abstract
An anti-corrosive superhydrophobic surface was successfully fabricated on a galvanized coating of a porcelain insulator’s pin in HVAC transmission line, using the New NaCl-SPS immersion method and stearic surface modification. After 3 days immersion in New NaCl-SPS solution, the stable passive layer was formed on the galvanized surface and it was confirmed as highly crystallized ZnO layer with hexagonal wurtzite structure, which is environmentally friendly. This work represents a new route for the synthesis of ZnO micro and nano-structures on the galvanized coating by immersion in New NaCl-SPS solution. Moreover, the superhydrophobic surface has been successfully fabricated on the synthesized ZnO surfaces. The corrosion resistance of galvanized surfaces with or without superdydrophobicity has been investigated. The results demonstrate that the superhydrophobicity can effectively enhance corrosion resistance, to counter pin corrosion problems of electrical insulators and porcelain breakage by volume expansion of corrosion products on the zinc sleeve.
