Abstract
In this work, fungal corrosion and inhibition behaviors of aluminum alloy 7075 beneath a thin liquid film were systematically investigated. Results demonstrate that Aspergillus terreus significantly accelerates localized corrosion with a high value of 4.693 mm/y which is 22.45 times the abiotic control. The addition of octadecylamine (OD), benzalkonium chloride (BKC), and imidazoline derivative (IM) effectively mitigates fungal corrosion by forming an inhibitor film and inhibiting the biological activity of A. terreus. The antifungal efficiency of IM is better, i.e., 91.5%. Antifungal uniform corrosion of IM is better while BKC possesses a higher inhibition efficiency (92.2%) for localized corrosion.
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.
