A large number of mechanical structural components in aircraft consist of aluminium alloys, which are susceptible to mechanical loads that erode mechanical properties and endanger the integrity of the aircraft. A time-dependent numerical model is developed in this study. The model provides insight into the complex effects of mechanical loading on the kinetics of galvanic coupling corrosion of AA7075 (aluminium alloy). Our results clearly show that mechanical loading accelerates galvanic corrosion, and the galvanic corrosion behaviour of aluminium alloys is significantly accelerated when loading induces plastic deformation; changes in the thickness of the thin liquid film affect the galvanic corrosion of the galvanic coupling model, which is suppressed when the film thickness is increased, and, in general, exhibits a stronger tendency to corrode homogeneously; the galvanic corrosion behaviour of aluminium alloys is significantly accelerated as the area of cathode increases; the simulation also reveals a higher localisation rate of the model when the boundary load is applied compared to the no-load case in the galvanic coupling corrosion behaviour. The numerical methodology illustrated in this study not only serves as a comprehensive tool for interpreting the intricate relationship between mechanical loading and corrosion behaviour, but also provides a framework for a deeper understanding of this multifaceted phenomenon. In practical applications, the model developed in this study can be used to check the safety of aluminium alloy structural components in service, which can be used as a reference for the design of aircraft wing skins.</p>","PeriodicalId":93746,"journal":{"name":"Electrochemical science advances","volume":"5 2","pages":""},"PeriodicalIF":4.1,"publicationDate":"2025-01-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/elsa.202400031","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143835961","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As AEMWE can operate at high efficiency without expensive Platinum Group Metal (PGM) catalysts or titanium cell components, required in state-of-the-art proton exchange membrane electrolysis (PEMWE), AEMWE has the potential to become a cheaper alternative in large-scale production of green hydrogen. In AEMWE, the porous transport layer and/or micro porous layer (PTL/MPL) has to balance several important tasks. It is responsible for managing transport of electrolyte and/or liquid water to the catalyst layers (CLs), transport of evolving gas bubbles away from the CLs and establishing thermal and electrical connection between the CLs and bipolar plates (BPPs). Furthermore, especially in case the CL is directly deposited onto the MPL, forming a catalyst-coated substrate (CCS), the MPL surface properties significantly impact CL stability. Thus, the MPL is one of the key performance-defining components in AEMWE.

The findings of this study are significant, as they provide valuable insights into the behaviour of Pt thin-film electrodes in various media and conditions. Two different approaches were adopted for the preparation of the electrodes: in one case, the Ti/Pt/Ti/Al<sub>2</sub>O<sub>3</sub> films deposited on sapphire wafers were exposed to rapid thermal annealing at 900°C under argon for 5 min, followed by argon ion milling to etch the final electrode pattern (Pt-RA(900)), while in the other case, uncapped Pt films were annealed, after etching, in a tubular oven under argon at specific temperatures between 200°C and 900°C (Pt-TO). Rapid annealing at 900°C on capped films resulted in the formation of a Pt<sub>3</sub>Ti intermetallic alloy with remarkable mechanical and chemical stability even after 10 h of immersion in deionised water, acid (0.1 M H<sub>2</sub>SO<sub>4</sub>) and alkaline media (0.1 M KOH) conditions at temperatures up to 150°C, despite the dissolution of the Al<sub>2</sub>O<sub>3</sub> top layer at 150°C and long immersion times (> 10 h).
