Study of corrosion evolution of carbon steel exposed to an industrial atmosphere
Source abstract
Abstract
The corrosion evolution of carbon steel exposed to an actual industrial atmosphere was investigated. The characteristics of the rust that formed on the steel were analysed by mass-loss measurement, X-ray diffraction, scanning electron microscopy and electrochemical techniques. Mass-loss results showed that the long-term corrosion kinetics of carbon steel can be divided into four stages, and that the corrosion rate varies during the different corrosion stages. This corrosion-rate fluctuation is attributed to the increase in the ambient temperature and the change in the composition of the rust layer formed on the steel surface. The reciprocal of charge transfer resistance (Rct) can be used to represent the corrosion rate. The backward-facing specimens were found to be more suitable as the objects to investigate the corrosion evolution. The evolution of the rust layer that formed on the steel is also discussed.
