利用湿砂土作为模拟土壤 ,通过失重法及电化学方法相结合 ,研究了盐浓差 (2 .0 %Cl- 及 0 .0 2 %Cl- )对LC4铝合金的宏电池腐蚀的影响规律。结果表明 :位于高盐土壤中的试样为宏电池阳极而加速腐蚀 ,宏电池作用强度达到 4.2倍。
The effects of salt concentration (2.0% Cl- and 0.2% Cl-) on the macrocell corrosion of LC4 aluminum alloy were studied by using wet sand as simulated soil by weight loss method and electrochemical method . The results show that the sample located in high salt soil accelerates the corrosion of the macro battery anode, and the macro battery has the strength of 4.2 times.
