摘要：
The inhibitive behavior of cadmium sulfate (CdSO4) on the corrosion of aluminum in 1 mol/L hydrochloric acid was investigated using fluorospectrophotometry and mass loss technique. Results showed CdSO4 was effective, especially at higher temperatures. Corrosion rate data obtained from the two techniques were consistent Potentiostatic polarization measurements showed the inhibitive behavior to be of cathodic rate control predominantly. The activation energies of the corrosion reaction in the absence and presence of CdSO4 were calculated. The inhibition mechanism was investigated using x-ray photoelectron spectroscopy and scanning electronic microscopy.
