Abstract

The transport behavior of sodium ions along a fusion-bonded epoxy coating-steel interface was investigated in 0.6 mol/L NaCl 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.

Key words: ion coating-steel interface transport
