摘      要：A new testing methodology was developed to quantitively study galvanic corrosion of AZ31B and thermoset carbon-fiber–reinforced polymer spot-joined by a friction self-piercing riveting ***-defined areas of AZ31B in the joint were exposed in 0.1 M NaCl solution over *** galvanic corrosion of AZ31B was observed as exposure time *** measured volume loss was converted into corrosion current that was at least 48 times greater than the corrosion current of AZ31B without galvanic *** percent of the mechanical joint integrity was retained for corroded F-SPR joints to 200 h and then decreased because of the massive volume loss of AZ31B。
