Electrochemical Behaviour of Low Carbon Steel in Aqueous Solutions

- An effective way of assessing corrosion in pipelines before serious consequences occur is to use tools that can predict the future of a pipeline through an understanding of its present state and the mechanisms of corrosion. In this work electrochemical methods such as liner and tafel polarization resistance were used to evaluate corrosion. Most metal corrosion occurs via electrochemical reactions at the interface between the metal and an electrolyte solution and, therefore, since corrosion occurs via electrochemical reactions, electrochemical techniques are ideal for the study of the corrosion processes. This particular study has examined the corrosion that occurred in different grades of low carbon steels with particular aggressive solutions. Corrosion rate measurements were obtained using different aqueous environments such as a plain sodium chloride solution, a sodium chloride and carbon dioxide solution, and a sodium chloride and sulphuric acid solution that also contained a smal...
