Abstract

Hydrophobic surfaces are effective on corrosion resistance as the contact with corrosive medium is reduced. In this study, a novel route integrating hydrothermal synthesis with ultraprecision machining (UPM) is reported to prepare a hierarchical cuprous oxide-stearic acid (Cu2O-STA) copper surface. Electrochemical methods were utilized to characterize the corrosion resistance performance. The results indicated that Cu2O-STA surfaces showed good corrosion resistance properties. The enhancement on the properties achieved via introducing UPM fabricated microgrooves was also revealed, by comparing the electrochemical behaviors of Cu2O-STA modified flat samples with the hierarchical surfaces based on Cu2O-STA modified microgrooves.
