Agricultural by-product of rapeseed meal extract as a highly efficient inhibitor for aluminum corrosion in HCl media: Experimental and theoretical studies
The inhibition performance of rapeseed meal extract (RME) on aluminum corrosion in HCl media was evaluated using weight loss method, electrochemical measurements, and surface characterizations. It is found that RME dramatically enlarges the charge transfer resistance of electrochemical reaction by inhibiting the cathodic reaction. RME can spontaneously adsorb on the aluminum surface to form a protective film, and this adsorptive behavior is consistent with Langmuir adsorption isotherm model. In addition, this adsorptive film with low fraction free volume (FFV) and self-diffusion coefficient (self-D) can strongly retard aluminum corrosion in HCl media with the highest inhibition efficiency of 99.0 %.
期刊介绍：
Corrosion occurrence and its practical control encompass a vast array of scientific knowledge. Corrosion Science endeavors to serve as the conduit for the exchange of ideas, developments, and research across all facets of this field, encompassing both metallic and non-metallic corrosion. The scope of this international journal is broad and inclusive. Published papers span from highly theoretical inquiries to essentially practical applications, covering diverse areas such as high-temperature oxidation, passivity, anodic oxidation, biochemical corrosion, stress corrosion cracking, and corrosion control mechanisms and methodologies.
This journal publishes original papers and critical reviews across the spectrum of pure and applied corrosion, material degradation, and surface science and engineering. It serves as a crucial link connecting metallurgists, materials scientists, and researchers investigating corrosion and degradation phenomena. Join us in advancing knowledge and understanding in the vital field of corrosion science.
