Aluminium corrosion inhibition using benzene‐1,2,4,5‐tetracarboxylic dianhydride (PMDH)

Aluminium corrosion inhibition using benzene‐1,2,4,5‐tetracarboxylic dianhydride (PMDH) Purpose – The purpose of this paper is to study the inhibitory activity of benzene‐1,2,4,5‐tetracarboxylic dianhydride (PMDH) on aluminium corrosion in hydrochloric acid 1 M HCl. Design/methodology/approach – The inhibitive effect of PMDH towards the corrosion of aluminium in 1 M HCl solution is studied by means of electrochemical impedance spectroscopy, polarization curves (LSV) and scanning electron microscopic techniques. The effect of inhibitor concentration and temperature against inhibitor action is investigated. Findings – In the presence of inhibitor (PMDH), the corrosion resistance of aluminium is improved and the corrosion rate and corrosion current are reduced, therefore the inhibition efficiency and polarization resistance are increased. With increasing temperature and decreasing inhibitor concentrations, the rate of aluminium corrosion increased. The surfactant acts as mixed type inhibitor and obeys a Langmuir isotherm. Originality/value – The results shown in this paper are an insight to the understanding of the corrosion resistance and electrochemical behaviour of aluminium for future industrial applications and development. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Anti-Corrosion Methods and Materials Emerald Publishing

The effect of inhibitor concentration and temperature against inhibitor action is investigated.

With increasing temperature and decreasing inhibitor concentrations, the rate of aluminium corrosion increased. The surfactant acts as mixed type inhibitor and obeys a Langmuir isotherm. Originality/value – The results shown in this paper are an insight to the understanding of the corrosion resistance and electrochemical behaviour of aluminium for future industrial applications and development.
