Abstract

Experiments were carried out in order to better characterize the intergranular corrosion process of 5086-H34 aluminum in sea water. Specimens were exposed at a constant potential in the range -0.75VSCE < corr < -0.83 Volts Saturated Calomel Electrode (VSCE). As a result, it was found that for a potential noble to -0.79VSCE intergranular corrosion indeed occurs. Under the same conditions 5052-H34 shows no intergranular attack. Since the major difference between these alloys is beta phase percent and distribution, this implies a minimum of this phase is required for intergranular corrosion to occur. Measurements of pH within simulated occluded cells were made in an attempt to obtain reasons for the observed -0.79VSCE threshold. The results of this did not point to any particular course which would explain this potential.
