Abstract
The influence of defects formed by dissolution of constituent intermetallic particles (IMPs) on the corrosion resistance of anodized aluminium alloys, including AA2024-T3, AA2198-T8, AA2198-T851, and AA7475-T761, is investigated. Localized corrosion initiates cavity defects located at the film/alloy interface, mainly due to the dissolution of high-copper-containing IMPs. In AA2024, Si-containing particle-induced defects also contributed to a reduction in corrosion resistance. Low-copper-containing IMPs in AA7475-T761 alloy, however, do not affect corrosion resistance. The effects of particle density, composition, size, and location on the formation of defects in anodic films and, subsequently, on corrosion resistance of anodized alloys are discussed.
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.
