Abstract
Amorphous cerium molybdate nanowires (CMN) have been used to impart active corrosion protective properties to hybrid sol–gel coatings on AA2024. Inhibitive ability of the novel sol–gel coatings against corrosion has been studied in detail by electrochemical impedance spectroscopy (EIS) and scanning vibrating electrode technique (SVET). Localized electrochemical measurements demonstrate significant suppression of corrosion activity in micro-scale defects made in sol–gel coatings loaded with CMN when compared to blank systems. The mechanism of active protection involves release of cerium and molybdate ions from the sol–gel coating during immersion in NaCl electrolyte and their inhibiting action in corroding defects.
