Master Thesis - Comparative Study of Material Analysis Techniques for Technical Cleanliness

30 credits – Comparative Study of Material Analysis Techniques for Technical Cleanliness Ingress: Thesis project at TRATON GROUP is an excellent way to make contacts for your future working life. Many of our current employees began their careers with a thesis project Background: Current way-of-working for technical cleanliness analysis relies on the usage of Scanning Electron Microscopy with Energy-Dispersive X-ray Spectroscopy (SEM-EDX) for cases when usage of light optical microscope is not enough and material composition is of importance. That leads to necessity of extra complex equipment, trained personell and increases the analysis time. Target: The thesis work will look into whether light optical microscope combined with Laser-Induced Breakdown Spectroscopy (LIBS) unit can serve as a replacement of SEM-EDX and can deliver similar analytic capabilities for materials of interest at Scania’s production, while reducing overall analysis time and simplifying the way-of-working. Assignment:

• Literature study of analytical methods.
• Selection of appropriate test material in collaboration with Scania’s Technical Cleanliness Laboratory.
• Analysis of particles in question by light optical microscope with LIBS and SEM-EDX, comparison of results.
• Analysis and conclusions.
• Recommendations for way-of-working based on light optical microscope with LIBS (if applicable).
