The corrosion behavior of 6082 aluminum alloy in the bolt connection structure of carbon fiber composite material-6082 aluminum alloy was studied using cyclic salt spray accelerated corrosion test, corrosion rate testing, corrosion morphology observation and electrochemical methods. The results show that after connection with carbon fiber composite materials, the coupling corrosion rate of 6082 aluminum alloy was 13 times higher than that of non connection 6082 aluminum alloy, and the corrosion at the contact between aluminum alloy and carbon fibers was the most severe. As the corrosion time prolonged, the corrosion potential of aluminum alloy gradually decreased, the corrosion current density increased, the corrosion resistance weakened, and the corrosion products on the surface of aluminum alloy gradually formed a dense and loose double-layer structure.
