Abstract
The effect of 1,5-diphenylthiocarbazone (dithizone) as an eco-friendly corrosion inhibitor for protection of AA7075 aluminium alloy in chloride containing aggressive environment was studied by means of weight-loss, electrochemical measurements and Raman spectroscopy. The results indicate that the addition of dithizone decreases significantly the corrosion rate of AA7075 alloy, with efficiency proportional to the inhibitor concentration. The polarization curves show that dithizone works as mixed-type inhibitor to slow down the anodic and cathodic reaction kinetic. The morphology revealed by scanning electron microscopy and the Raman spectroscopy analysis clearly shows that the inhibitor contributes in the formation of a stable protective film on the AA7075 alloy due to the adsorption of dithizone molecules on aluminium alloy surface obeying Langmuir adsorption isotherm.
期刊介绍：
Metallurgical Research and Technology (MRT) is a peer-reviewed bi-monthly journal publishing original high-quality research papers in areas ranging from process metallurgy to metal product properties and applications of ferrous and non-ferrous metals and alloys, including light-metals. It covers also the materials involved in the metal processing as ores, refractories and slags.
The journal is listed in the citation index Web of Science and has an Impact Factor.
It is highly concerned by the technological innovation as a support of the metallurgical industry at a time when it has to tackle severe challenges like energy, raw materials, sustainability, environment... Strengthening and enhancing the dialogue between science and industry is at the heart of the scope of MRT. This is why it welcomes manuscripts focusing on industrial practice, as well as basic metallurgical knowledge or review articles.
