AB The 6061 alloy is used in different thermomechanical conditions in research nuclear reactors.Nuclear fuel plates are manufactured by the picture frame technique (PFT) and the 6061 alloy isused as cladding for the nuclear fuel “sandwiches”. After the process, these nuclear plates areplaced in a case composed of 6061-T6 alloy. In this work, the galvanic effects of coupling the6061 alloy in the T6 and PFT conditions on the corrosion behavior was investigated in solutionsof different chloride contents. The results showed that galvanic corrosion was favored due to thedifferent microstructural features related to these two thermomechanical conditions of the 6061alloy. The 6061 alloy in the PFT condition was cathodic to the alloy in the T6 condition. Localelectrochemical techniques were useful in characterizing the electrochemical behavior of thecoupled alloys.
