| Semester : S9 |
Person(s) in charge:
Silvère BARRAT, Professor, silvere.barrat@mines-nancy.univ-lorraine.fr |
Keywords: Wear and corrosion of metallic materials |
Prerequisites: |
Objective 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).
