## Abstract Experiments are performed to study the influence of applied potential and chloride concentration on the kinetic behaviour of pitting corrosion initiation for unalloyed aluminium. A potentiostatic method is used at 30Β°C in deaerated solutions of sodium chloride. The pitting potential, E~
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
The stress corrosion cracking behaviour of plate material of the aluminium alloys 2024-T351, 8090-T8171, 7475-T651, and 7075-T7351 was investigated performing constant load tests. Short transverse tensile specimens were permanently immersed in aerated aqueous 0.6 M Na 2 Cl solutions with additions o
