Abstract
The tribocorrosion behavior of 7075-T651 aluminum alloy in chloride environment with different pH is investigated. In acidic and alkaline environments, the attack of Cl- and OH- results in the larger wear volume as compared to the neutral environment. The friction coefficient decreases with an increase of load, showing the highest value in alkaline solution. The synergistic effect of corrosion and wear is promoted in alkaline solution, while it is inhibited in the acidic and neutral solutions. At open circuit potential and the anodic potential, the wear mechanisms in acidic and alkaline solutions are corrosion fatigue and adhesive wear.
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.
