Abstract:The corrosion behavior of LY11 aluminum alloy in acid, alkaline and neutral soil after burying for 1, 3 and 5 a was studied. It is shown that localized corrosion is the major behavior Of LY11 aluminum alloy in soil, and corrosion of LY11 depends on the soil texture: severe corrosion oecurs in the heterogeneous alkaline and acid soil, and slight corrosion occurs in homogeneous neutral and acid clay soil.

 

Key words:  LY11 aluminum alloy; soil corrosion; corrosion behavior
