Kinetic study on corrosion of steel in soil environments using electrical resistance sensor technique

Corrosion of steel in soil environments was monitored by thin film electrical resistance sensor having high sensitivity for corrosion rate measurement. The results show that this sensor made it possible to predict the long-term corrosion behavior of steel expressed by a kinetic curve obeying power law within a short period. Moreover, the effect of soil resistivity on corrosion rate measurement was eliminated using this sensor.
