摘要

The galvanic corrosion behavior of 6082 aluminum alloy coupled to SUS304 was assessed in various NaCl solutions to simulate the various salt water environments. Results showed that the 6082/SUS304 couple was composed of macro-couple (6082/SUS304) and micro-couple (Mg₂Si or Al(Mn, Fe, Cr, Cu) Si coupled to α-Al), and the galvanic corrosion process intensified with the increased NaCl concentration, especially the Mg₂Si micro-couple experienced a polarity reversal. The erosive effect of Cl⁻ induced the corrosion products to exhibit an evolution tendency of “Al₂O₃ → Al(OH)₃ → Al(OH)_3−xCl_x → AlCl₃”. Furthermore, the distributions of potential and current susceptible to the 6082/SUS304 structure were simulated by COMSOL (FEM) and the mechanisms were discussed.
