Graphene nanoplatelet on stainless steel substrate
The research project aims to improve wear resistance of materials using thermal sprayed graphene coatings. Graphene is well-known in tribology for its outstanding lubricating properties. The use of thermal spray for the deposition of graphene coatings could provide a fast and cost-effective way of enhancing wear resistance and reducing friction in many mechanical applications.
To accomplish such goal, three main pieces of equipment are used:
Scanning electron microscopy
- Non-destructive interaction of electrons with matter.
- Morphological characterisation up to nanometre scale.
- Elemental mapping using energy dispersive x-rays spectroscopy.
Raman spectroscopy
- Excitation and detection of vibrational modes in materials.
- Individuation and mapping of elements in a particular aggregation state.
Tribometer
- Measurement of frictional force and coefficient of friction under different loads.
- Understanding and improvement of wear mechanisms.
