摘要
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 effect of salt concentration difference macrocell (2.0% Cl - and 0.2% Cl - ) on the corrosion of LC4 alumimium alloy was studied in the simulated soil of moisture sands by means of mass loss and electrochemistry. It is shown that the corrosion rates of samples in the higher salt concentration soil were accelerated as cathods, and the rate of the macrocell effect was 4.2 times. [
