Abstract
The effect of Li content (0.5 wt%, 1.0 wt%, 1.5 wt% and 2.0 wt%) on corrosion resistance of Al-Li alloy was studied in 3.5 wt% NaCl. The corrosion resistance is affected by changes in the characteristics of the corrosion product layer caused by variations in Li content. The alloy with 1.5 wt% Li exhibited the best corrosion resistance, which is attributed to Li2CO3 generated on its surface. Li2CO3 layer acted as a barrier to corrosive Cl- and O2. The wide bandgap of Li2CO3 hindered the transfer of electrons, increasing the resistance of cathodic reaction and retarding further 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.
