Background and activities

Nuria Espallargas (1979) is a Professor at the Department of Mechanical and Industrial Engineering. 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 2011.

Research Interests

  • Surface chemistry and engineering.
  • Tribology and tribocorrosion.
  • Lubricants, including environmentally acceptable.
  • Nano-tribology.

I perform basic research on degradation phenomena of surfaces exposed to aggressive chemical environment. My research focuses on understanding the chemo-mechanical degradation phenomena starting on surfaces. This knowledge enables finding solutions to make more durable and performing materials, to contribute to a greener world.

I also perform reserach on developing new lubricant formulations for the green shift. To reach the UN Sustainable Development Goals by 2030, Environmentally Acceptable Lubricants (EAL) will be a requirement in many fields. In that sense, my background as chemist and tribologist enables the implementation and development of EALs for a greener future.

Controlling surface chemistry is the ultimate goal of my research. Surface chemistry plays a role both in lubricant formulation and degradations of materials, and it is key to add functionality to surfaces for finding new solutions to materials problems. Understanding the surface mechanisms and phenomena across scales (from nano-to-macro) is crucial to solve the degradation of materials to design and optimise surface solutions.

Main topics of my research projects

  • Tribocorrosion mechanisms - coatings and metals.
  • Multidegradation - the interaction of tribocorrosion with fatigue.
  • Experimental nano-tribology. 
  • Environmentally acceptable lubricants and water lubrication.
  • Coatings and surface treatments for tribocorrosive environments.
  • Synthesis and production of ceramic based feedstock materials for thermal spraying.
