Abstract

Using electrochemical techniques, especially the electrochemical impedance spectroscopy (EIS), the scanning electron microscopy (SEM) technique and the polarization measurement (PDP) have been all used to explore the 2,5-dihydro-4H-pyrazolo[3,4-d]pyrimidin-4-one (PPO) inhibitive action against the degradation of the mild steel (MS) in acidic media(1 M HCl). What is found has shown that PPO is the MS corrosion's perfect inhibitor in the 1 M HCl. According to PDP studies, the inhibitor under study is a mixed type. PPO adsorption on the outside of the studied steel is measured in conformity with the Langmuir isotherm. It was revealed in the surface investigations (SEM/EDS) that PPO could prevent MS damage in HCl (1 M) medium. This latter was found, according to the demonstration of contact angle (CA) estimations, to be hydrophobic. Experimental result upholds the outcomes got from DFT method and Molecular Dynamics Simulation (MDs).
