BASHIR, S. et al. Inhibition Performances of Nicotinamide Against Aluminum Corrosion in an Acidic Medium. []. , 38, 2, pp.107-123. ISSN 0872-1904.  https://doi.org/10.4152/pea.202002107.

The non-toxic anticorrosion properties of nicotinamide have been studied on aluminum in an acidic medium. The techniques included weight loss method, electrochemical measurements, quantum chemical calculations, Monte Carlo simulation, infra-red spectroscopy and scanning electron microscopy. This study gathers information about the inhibitor molecule adsorption onto the surface of metal specimens. Thermodynamic parameters were utilized to predict the adsorption mechanism. The dependence of corrosion inhibition efficiency on various parameters was examined, and it was seen that the increase in the inhibitor concentration and in temperature led to an increase in the inhibition efficiency. The dipole moment and E_HOMO-E_LUMO influenced the inhibition efficiency, which was observed by quantum chemical studies.
