Course Overview

Course scope:

  1. Tribological contact of two surfaces: contact geometry, line, point and Hertz contact, contact of two curved non-conformal bodies, forces, sliding speeds and stress in the contact, line, point and are loading, Hertz teory, tangential loading, combination of normal and tangential loading – sliding, micro and macro sliding, stick-slip, rolling.
  2. Elasto-plastic contact, elastic deformation, plastic deformation, plastisity index.
  3. Contact of rough surfaces, surface roughness and topography.  Temperatures in tribological contact: moving and fixed heat source, temperature field, termoelastic contact.
  4. Surface characterization: microscopy, optical and scannin electron microscopy, atomic force microscopy.
  5. Surface composition and structure: EDS, X-Ray, IR, XPS, Auger,...
  6. Profilomety and topography: advanced surface roughness parameters and their analysis, surface load carrying-capacity, surface texturing.
  7. Surface hardness and elasticity, Young's modulus.
  8. Residual stress, measuring principles, utilization and residual stress effect.
  9. Coating adhesion.
  10. Wear and friction properties of different coating materials, model tribotesters, simulations, real element testing.
  11. Surface engineering technologies: surface texturing, surface coating technologies, substrate preparation, selection criteria
  12. Types and properties of surface layers: difusion layer, metalic coatings, cheramic coatings, diamond and dimond like carbon coatings, multicomponent, multilayer and nanostructured coatings.
  13. Tribological properties of surface engineered surfaces, influence of thickness, hardness, residual stress, roughness and elasticity.
  14. Contact mechanics of layered surfaces, stress-strain field of coated surfaces and Yield maps for surface engineered contacts.
