Bachelor- / Master’s thesis: Optimization of Boundary Layer Formation for Enhanced Wear Protection in Rolling Contacts (Tribology, Two-disc tribometer, Friction, Wear protection)

Webseite Institute of Machine Elements and System Engineering

The Institute of Machine Elements and System Engineering researches the fundamental structural and tribological behaviour of machine elements and represents them in experimentally validated model descriptions. These model descriptions are used to analyse and design the functional, loss and noise behaviour of entire technical systems with a focus on drive technology. The developed models are also used to research and develop methods of Model Based Systems Engineering as a central element of future inductive product development processes.

Rolling contacts, such as those found in bearings, gears, etc are integral components of numerous mechanical systems. The efficient operation and longevity of these systems depend on the intricate interplay between the contacting surfaces and the lubricating environment. One critical aspect that significantly influences the performance of rolling contacts is the formation and behaviour of tribolayers. These thin films, which develop at the interface between the contacting surfaces, play a pivotal role in reducing friction, minimizing wear, and enhancing the overall efficiency and durability of the systems. This thesis vacancy offers an exciting opportunity to contribute to the improvement of wear protection in rolling contacts by optimizing the boundary layer formation. The project aims to investigate the influence of boundary layer formation on wear protection in rolling contacts.


  • Conducting a comprehensive literature review on the wear behavior of rolling contacts, boundary layer formation, and wear protection mechanisms.
  • Performing rolling contact experiments under various contact parameters to study the formation of wear-protective boundary layers.
  • Analyzing experimental data to identify correlations between initial boundary layer properties, contact parameters, and wear behavior.


  • Independent and reliable working
  • Interest and an open mind to learn new things
  • Background knowledge in tribology, experimental methods, and data analysis.
  • Familiarity with rolling contact behavior and wear mechanisms.

We offer:

  • Intensive supervision
  • Immediate start or by appointment
  • Excellent working atmosphere
  • Suitable for homeoffice
  • Promising topic and experience for a future career
