摘要
使用离子选择性微电极对0.6 mol/L NaCl溶液(60℃)中Na+在一种环氧粉末涂层/Q235钢界面上的传输行为进行了研究,并基于Fick第二定律建立了数学模型。结果表明,实验结果和模型吻合较好,依据模型计算得到的Na+表观扩散系数与前人的结果相符。
The transport behavior of sodium ions along a fusion-bonded epoxy coating-steel interface was investigated in 0.6 mol/L NaC1 solution （60 ℃ ） by ion selective microelectrode. Based on Fick＇s second law a mathematical model was established. The results showed that experimental results was coincided with mathematical model well. The calculated apparent diffusion coefficient of Na＋ by model had similar order of magnitude with previously reported values.
