Master Thesis Opportunity: Fatigue Characterization of Anodized Aluminium Alloys

Location: Alstom Västerås / RSC Traction Design and test facilities at University
Department: Traction Design
Duration: 20 weeks (Master’s thesis)
Language: Swedish and/or English
Number of Students: 1
Possibility to work from our office: Yes

Background

Several enclosures and support structures at Alstom are manufactured from anodised and cold-sealed anodized aluminium. While anodization improves wear and corrosion resistance, it is known to negatively affect the fatigue properties of aluminium alloys. The effect of cold sealing on restoring fatigue performance is not well understood. This thesis aims to clarify these effects, enabling more efficient material use in our designs.

Thesis Objectives

• Conduct fatigue tests on Al 5754-H22 in three conditions: raw (non-anodised), anodized and cold-sealed Anodized (t = 3 mm).
• Evaluate and compare the fatigue properties of each condition.
• Compare experimental results with the EUROCODE curve.
• Recommend design improvements to optimise material use (potentially reducing material usage by up to 30%).

Main Activities

• Introduction to Eurocode 1999-1-3:2023.
• Learn how to derive fatigue curves from test data and select appropriate statistical methods.
• Produce test specimens.
• Perform experimental tests and estimate S–N curves.
• Draw conclusions and prepare a final report.

Candidate Profile

• Background in Mechanical Engineering.
• Understanding of structural design and fatigue strength analysis.
• Familiarity with laboratory test environments.
• Strong analytical skills and a systems-thinking mindset.
• Good report writing skills

Additional Information

• • • The project is suitable for a single master’s student.
