Abstract

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.

期刊介绍： Materialia is a multidisciplinary journal of materials science and engineering that publishes original peer-reviewed research articles. Articles in Materialia advance the understanding of the relationship between processing, structure, property, and function of materials. Materialia publishes full-length research articles, review articles, and letters (short communications). In addition to receiving direct submissions, Materialia also accepts transfers from Acta Materialia, Inc. partner journals. Materialia offers authors the choice to publish on an open access model (with author fee), or on a subscription model (with no author fee).
