TRACC: Triboactive Component Coatings based on Fullerene-like WS2
Centrum Partners:
- Urban Wiklund, Ulf Jansson, Karin Larsson, Lars Hultman, Sture Hogmark, Åsa Kassman
- PhD student Nils Stavlid
Scientific Objectives
- Investigate inorganic fullerene-like layer systems that during tribological loading spontaneously form low friction layers.
Technology Transfer Objectives
The project fits our established network of industrial partners, including job coaters, steel makers, tool makers, oil companies and mechanical industry very well:
- Initiate at least four of the following partners in project meetings and work shops: Volvo, ABB, Scania, Hägglunds Drives, Agro Oil, Sandvik, Balzers,
- Associated EU-project FOREMOST.
Some of the industrial partners will be closely involved in the project while a broader group will be invited to the industrial seminars within MS2E as well as to the annual Ångströms Tribomaterialdagar, and similar occasions.
Research plan:
- Development of tribological coatings is based on knowledge of their performance and limitations in tribological contacts. Our nanotribological test equipment will employed.
- Developing triboactive systems requires a very broad approach, involving basic chemistry, theoretical modeling, metallurgy and insights into the tribological details. A number of promising candidate systems have been identified. The first to be investigated are found within the inorganic fullerene like materials (initially WS2 based).
- High resolution microscopy and analyses using techniques as FIB, TEM and ESCA will be used to understand the chemical and physical processes for the formation of the low friction surface layers as well as the tribological behavior of the coated contact system.
