This paper evaluated the inhibitory effect of Ce‐chloride and Na‐lactate
mixture on the AA2024 aluminum alloy in 0.1M NaCl solution. Electrochemical
impedance spectroscopy (EIS) was applied for testing the general
corrosion resistance, while potentiodynamic polarization measurement was
applied for determining the alloy pitting corrosion resistance in NaCl and
inhibitive solutions. The presence of cerium on the cathodic intermetallic
particles was confirmed by scanning electron microscope/energy‐dispersive
X‐ray spectroscopy analysis. The mixture of Ce‐chloride and Na‐lactate was a
more effective corrosion inhibitor than Ce‐chloride alone. The inhibitors
mixture is a mixed‐type corrosion inhibitor with a higher influence on slowing
down the cathodic reaction of oxygen reduction. The adsorption of the
inhibitor, the presence of cerium in different oxidation states (Ce3+ and Ce4+),
and lactate anion (C–C/C–H, C–OH, C═O, and O–C═O group) were confirmed
by X‐ray photoelectron s...pectroscopy analysis. A mechanism of inhibitor
adsorption on the surface of AA2024 alloy in NaCl solution was proposed.
