Master’s thesis: Cost-Effective Tribofilm Characterization: Leveraging the Contact Angle Method as an Alternative to Advanced Surface Analysis

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, and other machine elements are integral components of numerous mechanical systems. The efficient operation and longevity of such systems depend on the intricate interplay between the contacting surfaces and the lubricant. One critical aspect that significantly influences the performance of such contacts is the formation and behavior of Tribofilms. These thin films, which develop at the interface between the contacting surfaces, play a pivotal role in enhancing the overall efficiency and durability of the systems. The properties of these films (like homogeneity and composition) are crucial to their behavior and are traditionally examined using costly and sophisticated microscopic and spectroscopic techniques. This thesis offers an exciting opportunity to predict the properties of these Tribofilms with a cheaper and easier alternative, i.e., the contact angle method.
