The corrosion rate was found to increase, in order, Al base metal (BM-6N01) < Mg base metal (BM-AZ31B) < stirred zone. The galvanic coupling of the Mg phase to the other phases enhanced the corrosion of both BM-AZ31B and BM-6N01. Accompanying the intense corrosion at BM-AZ31B, water reduction on the cathodic particles of BM-6N01 elevated the interfacial pH to a level where the Al matrix corroded to AlO2?. ? 2020 Elsevier LtdAluminum corrosion; Corrosion rate; Corrosive effects; Friction; Friction stir welding; Galvanic corrosion; Magnesium alloys; 6N01 aluminum alloys; AZ31B magnesium alloys; Corrosion behavior; Dissimilar joints; Galvanic corrosion behavior; Galvanic coupling; Hydrogen evolution; Realtime imaging; Aluminum alloys[SDGs]SDG7journal article10.1016/j.corsci.2020.1092032-s2.0-85098538346
