Abstract
An additively manufactured aluminium alloy with very high solute content, Al-14Zn-3Mg (wt. %), was studied herein. Compared to wrought AA7075-T6 as a benchmark, Al-14Zn-3Mg revealed a lower rate of corrosion, attributed to its microstructure and solute content. Specifically, the lack of coarse intermetallic particles in the Al-14Zn-3Mg led to reduced cathodic kinetics relative to AA7075-T6. Potentiodynamic polarisation tests and electrochemical impedance spectroscopy analysis was performed, along with XPS studies of the corresponding surface films. The findings herein demonstrate the corrosion behaviour of a new high solute aluminium alloy manufactured in net shape through LPBF.
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.
