Background and activities

Nuria Espallargas (1979) is a Professor at the Department of Engineering Design and Materials. She has a MSc in Chemistry from University of Barcelona (Spain) and a PhD in Metallurgy and Materials Engineering from the same university.

She is also the NTNU leader of the Gemini Centre “Tribology” since 2012.

She has supervised 3 graduated doctoral candidates, and is currently supervising and co-supervising 8 PhD candidates and 2 postdocs.

Research Interests

  • Surface chemistry and engineering.
  • Tribology and tribocorrosion.
  • Nano-tribology.

The main motivation is to perform basic research to understand degradation phenomena that starts on metal surfaces exposed to aggressive environment. Under these conditions metals are typically covered by oxides, which greatly affect wear and friction. The focus is to understand the degradation phenomena of materials exposed to chemo-mechanical effects.

Surface engineering is the key to add functionality to surfaces and therefore finding new solutions to materials problems by controlling their surface chemistry is the ultimate goal of my research. In addition, understanding the mechanisms at the nano, micro and macro scale is crucial to solve materials degradation therefore the other goal of my research is to perform testing across scales to design and optimise surface solutions.

I find my research relevant for different types of applications, i.e. oil&gas, drilling and tunneling, biomaterials, sports and renewable energy (wind and solar).

Main topics of research projects

  • Tribocorrosion mechanisms in coatings and metals.
  • Multidegradation - the interaction of tribocorrosion with fatigue.
  • Nano-tribology for offshore materials.
  • Coatings and surface treatments for use in tribocorrosive environments.
  • Chemistry for developing new materials for thrermal spraying.
  • Environmentally Acceptable Lubricants and water lubrication for offshore applications.
  • Galling/adhesion mechanisms of metal forming.
  • Low temperature tribology.
