Description/Abstract:
Experiments on galvanic corrosion of aluminum when coupled to stainless steel or graphite are described. Observations of static corrosion, at 50° C and 90° C, were made over a period of 60 days for the cases of distilled, demineralized, and simulated Hanford process water, both with and without 0.005M H2O2. The rate of aluminum pick-up by the water ranged from 0.0016 to 0.07 mg/cm2/day at 50° C and from 0.007 to 0.11 mg/cm2/day at 90° C, and the corrosion rate increased with time. Pit depths varied from 0 to 5 mils after 2 months in distilled or demineralized water and from 20 to 40 mils in simulated Hanford water.
