Duration : 21 hours

ECTS Credits :

Semester : S9

Person(s) in charge:

Silvère BARRAT, Professor, 


Wear and corrosion of metallic materials




Control of wear and corrosion of metallic materials

Program and Contents:

  •  Solid surface topography - characterization and analysis of surface roughness.
  • Definition and history of tribology. Industrial significance. Definition of a tribological system.
  • The understanding of solid contact mechanics to optimize industrial applications.
  • The laws of “dry” friction. The various types of friction: Static and dynamic friction, sliding, rolling, viscous and aerodynamic friction.
  • Basic wear processes: abrasive wear and mechanisms, adhesive wear, rolling contact wear.
  • Wear quantification: the different types of machines, Archard’s law.
  • Friction and wear examination of engineering materials (rotation of a helicopter engine, crankshaft journal).
  • Introduction to water corrosion for metallic materials: thermodynamic and kinetic aspects,
  • introduction to galvanic series. Costs of corrosion and the means to reduce them. The different types of corrosion: uniform corrosion, galvanic corrosion, crevice corrosion, pitting corrosion, intergranular corrosion, selective corrosion, erosion corrosion, stress corrosion, hydrogen corrosion. Application of corrosion in the petroleum industry (guest lecturer in this field).
