Abstract
In this study, an Al/Mg lap joint was produced employing laser-arc hybrid welding with introducing a Ti interlayer to suppress the formation of brittle AlMg phases. The corrosion behaviors of the lap joint were evaluated in NaCl solution by electrochemical methods. The results showed that the weld joint revealed a flawless connection but complex in the microstructure and phase composition within the joint. The corrosion was initialized by the galvanic coupling between Mg/Al alloys, but their role was exchanged periodically due to the unsimilar properties of corrosion products layer and the increasing pH of the local electrolyte during the immersion.
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.
