Description:
The possibility of detecting a change in the corrosion mechanism of carbon steel by analyzing acoustic-emission (AE) signals was investigated. The change in the corrosion mechanism of steel 20 with a change of pH was modeled in citrate buffers at various pH values. The overall steel corrosion rate, polarization curves, corrosion products, and AE signals associated with steel dissolution were analyzed. It was shown that AE monitoring of the overall corrosion of carbon steel could not only estimate the extent of corrosion but also detect changes in the corrosion mechanism.
