Resumo
The effects of friction stir welding (FSW) on the corrosion resistance of the AA2098-T351 aluminum alloy were investigated through immersion and electrochemical tests in a 0.005 mol L⁻¹ NaCl solution. The findings revealed that the welding joint (WJ), which includes the thermomechanically affected zone (TMAZ) and stir zone (SZ), demonstrated superior localized corrosion resistance compared to the HAZ and BM. The SZ and TMAZ demonstrated cathodic behavior relative to the HAZ and BM. Furthermore, the differences in corrosion resistance among the isolated welding zones and their behavior under galvanic coupling were analyzed and discussed, highlighting the complex electrochemical interactions within the welded structure.
