Abstract
The exfoliation corrosion resistance of 7020 aluminum plate treated with different quenching rates after solution treatment was investigated through standard exfoliation corrosion (EFC) immersion tests combined with scanning electron microscopy (SEM). The results showed that the EFC resistance of this alloy plate decreased with the decrease of quenching rate. The corrosion rank ranged from EA to ED, and the maximum corrosion depth ranged from 388 to 570 μm.
