Purpose and goal
The main purpose of this project is to unveil the structure and molecular composition of the boundary layers induced by the novel ionic liquids using Near Edge X-Ray Absorption Fine Structure (NEXAFS) spectroscopy combined with angle resolved X-ray Photoelectron Spectroscopy (XPS). Such knowledge will enable development of more efficient (low friction and wear) lubricant formulations for industrial and automotive applications with a special focus on electric machinery.
Expected results and effects
The project will contribute to the development of the experience and competence in using synchrotron based surface analysis techniques in both academia and industry. Industrial collaborators will benefit in getting the knowledge on how to apply such spectroscopic techniques to enable more enhanced lubricant formulations. Project results will also help with the development of low friction and wear lubrication technologies for electric machinery contributing to the work towards carbon neutral society.
Planned approach and implementation
Model lubricant formulations will be designed together with the participating companies. They will be tested using tribometers at the participating companies to show our industrial collaborators how to prepare samples for the surface analyses at the synchrotron facility. A combination of NEXAFS and XPS will be used to analyse molecular composition and structure of boundary films formed on the test surfaces to get the most accurate information about their nature. Data analysis will be performed with the help of a beam-line scientist.
