| Abstract: | Research on the corrosion behavior of LC4CS and LY12CZ aluminium alloys in the exfoliation solution is made. The reason of intergranular corrosion and exfoliation corrosion is analyzed. By a comparative study of tension and corrosion fatigue experiments of exfoliation corrosion and unexfoliation corrosion specimens, the influence of exfoliation corrosion on aluminium is researched. The result shows that the microstructure of alloy has varied with exfoliation. |
