摘要

In the present work, AA2139 rolled sheets were friction stir welded in butt joint configuration and anodized in sulfo‐tartaric acid solution. Both the microstructure and the corrosion behavior of the joints were studied. Electrochemical spectroscopy measurements were carried out in aggressive soluti...
