Abstract

Magnesium alloys continue to play a significant role in the context of lightweight structural materials, albeit that corrosion susceptibility remains a limit to their wider use. Most research to date has focused on aqueous corrosion of Mg alloys, whilst atmospheric corrosion remains poorly understood. Using atom probe tomography and a novel in-situ coating method, the native oxide layer in an additively manufactured Mg-Al alloy (AZ111) was investigated. Aluminum was found to diffuse outwards during oxidation and to be incorporated into a Mg-oxide/hydroxide rather than forming the postulated Al₂O₃ layer. This study advances the understanding of magnesium oxidation.

利用原子探针层析成像技术研究镁铝合金大气腐蚀过程中Al的扩散路径
镁合金在轻量化结构材料中继续扮演着重要的角色,尽管腐蚀敏感性仍然是其广泛使用的限制。迄今为止,大多数研究都集中在镁合金的水腐蚀上,而对大气腐蚀的了解仍然很少。采用原子探针层析成像技术和一种新的原位涂层方法,研究了增材制造Mg-Al合金(AZ111)的天然氧化层。研究发现,铝在氧化过程中会向外扩散,并与镁氧化物/氢氧化物结合,而不是形成假设的Al₂O₃层。本研究促进了对镁氧化的认识。

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.
