摘要:The corrosion and passivation of 3003 aluminium alloy in synthetic solution similar to industrial water at pH = 8.2 were studied by electrochemical techniques. The effect of the following factors on the dissolution and passivation of this alloy are discussed: heat treatment, pH solution, temperature of medium and chloride ions. Surface analysis was investigated by X-ray analysis (EDS) and scanning electron microscope (SEM). Heat treatment was carried out during 2h at temperatures varying between 350 and 550°C. Potentiodynamic polarization result showed that the corrosion behaviour is performed for treated sample at 450°C. The ability of pitting corrosion increases with the elevation of chloride concentration and the uniform corrosion is affected by the temperature of corrosive medium.
