Abstract
The remanufacture of damaged conversion coatings requires a dry-in-place, no rinsing process. This work reports a novel brushing conversion treatment method. The SEM and TEM analyses demonstrate a porous but more compact structure, whereas electrochemical measurements prove an enhanced corrosion resistance of brushing conversion coatings, as compared with the conventional immersion coatings. The more compact structure was ascribed to the accelerated coating growth kinetics under the continuous brushing, and the enhanced corrosion resistance was attributed to the retard of the penetration of corrosive ions in the maze-like porous structure.
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.
