The composition of the passive layer on aluminium and reformation of this layer during cathodic polarization were investigated by radiotracer and electrochemical methods in the presence of sulphate and chloride ions. Chloride ion is not ab-or adsorbed on the passive layer but, attacks this layer as
## Abstract A literature survey has lead to the conclusion that a theory which postulates an increased anodic reactivity on a local site in the passive film is very probable. Experiments have been set up to confirm these suggestions. By means of the electronβmicroanalyser, it is shown that CI^β^ion
