Surface Engineering

A surface determines many properties of a component, apparatus, or instrument walls and strongly influences its interaction with the surrounding environment, including solid particles, droplets, liquids, and gases. These interactions govern phenomena such as friction, collision and adhesion, wetting, and heat transfer.

Our research focuses on surface modification and surface-particle interactions, with particular emphasis on the following areas:

  • Development of tailor-made surface properties using various coating and microstructuring processes to modify tribological properties (friction and wear), mechanical performance, and to protect surfaces against mechanical, chemical, and thermal loads by coating
  • Cold spray coating and microstructuring of surfaces
  • Additive cold spray 
  • Characterization of mechanical, tribological and wetting surface properties 
  • Contact interactions with particles and droplets
