Abstract:
<p class="MsoBodyText" style="margin-top:.1pt;text-align:justify">This work focuses on the study of a new ecological corrosion inhibitor,
namely polyphenol. The polyphenol used is extracted from vegetable waters and
olive pomace, which constitute the waste of the olive industries. The
extraction of olive oil generates large quantities of solid and liquid
by-products, olive pomace and vegetable water. Both by-products are harmful to
the environment. The study focuses on two inhibitors (polyphenol extracted from
vegetable waters (MA) and polyphenol extracted from pomace (GO)). The tests are
carried out on high tensile strength steel (AHLE), widely used in the
automotive industry, for its mechanical characteristics and its forming
properties. This study was performed using the weight loss method,
potentiodynamic polarization and electrochemical impedance spectroscopy (EIS).
The gravimetric measurements indicate that the effectiveness of the inhibitor
increases with the concentration reaching a maximum value of 96% at 10-3 M.
Moreover, the electrochemical study shows that the effectiveness of the two
inhibitors (MA and GO) on the HLE steel is 95.70% and 95.23% respectively.</p>
