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 reactio...

The Effect of Solution Concentration on the Electrochemical Behaviour of AISI 321 Stainless Steel in Sulfuric Solutions

Electrochemical Studies of Pitting Corrosion of Cu-fe Alloy in Sodium Chloride Solutions

The electrochemical studies of pitting corrosion of CuFe alloy (70% Cu30%Fe) were carried out in sodium chloride solutions. The techniques of measurements were: open circuit potential, potentiodynamic polarization and electrochemical impedance spectroscopy. The effect of different concentrations of the inorganic additives (WO4 , PO4 , NO2 , B4O7 , CrO4 ) on the pitting corrosion of the alloy in...

Electrochemical behaviour of lead in hydrochloric acid solution in the presence of inorganic ions

The electrochemical behaviour of lead electrode in hydrochloride solution containing variousoxo-anions at different concentrations was studied by using of cyclic voltammetry (CV) method.Results obtained show that the addition of these inorganic compounds decreases the anodic andcathodic currents peaks according to the following order: H2PO4- > HPO42-> SO42-. It’s revealedalso that the cathodic ...
