ABSTRACT:
The purpose of this study to investigate the effect of pyrazolo [3-4-b] pyridine on the corrosion inhibition of stainless steel in 1.0M hydrochloric acid (HCl) by using the following methods: the weight loss method, the potentiodynamic polarization methods, and the electrochemical impedance spectroscopy. It was found that the adsorption of inhibitor could prevent steel from weight loss and the adsorption accorded with the Langmuir adsorption, the corrosion protection could be explained by the adsorption of inhibitor and formation of a protective layer attached to the metal surface.
