Purpose and goal

Hydropower sources produce stabalizing environmentally friendly energy. The service life of the components and tribological performance of the bearing material is crucial to be able to guarantee as little as possible stop within production line. Thus, new and improved bearing materials which can be used together with water or other environmentally adaptive lubricants (EAL) are very important for the hydropower industry. The goal in this project is to develop wear resistance graphene based composites as bearing material which can perform with both water and EAL.

Expected results and effects

Increase of the collaboration between academia for knowledge transfer "with focus on graphene" from fundamental research directly to the end user industry in Sweden. This will potentially introduce new and innovative composites to the Swedish hydropower industry. Also Introduction of new oil free glycerol based lubricants in combination with new graphene based composites in hydropower industry and other relevant industries such as wind power to invest in graphene based materials and new oil free lubricants in their components

Planned approach and implementation

Work packages are planned as following. WP1: production of the surface-modified graphene derivatives. WP2: manufacturing of graphene based polymer composites. WP3: tribological evaluation of the new composites. WP4: evaluation of the new EA-lubricants. WP5: aging and service life evaluation of the new composites. WP6: design of the component. LTU is responsible for research and development in material development, tribological characterisation, service life and aging evaluation of graphene based composites in WP1-5. LTU will work closely with VF and Sustainalube in WP4-6.
