| Résumé : |
Fretting-corrosion is a combined damage mechanism involving corrosion at points where two moving metal surfaces make rubbing contact. It is a special wear process that occurs at the contact area between two materials under load and subject to minute relative motion by vibration or some other forces. The amplitude of the relative movement may be very small, typically of the order of a few microns. Virtually ail machines vibrate, fretting occurs in joints that are bolted, pinned, press-fitted, keyed and riveted; between components that are not intended to move; in oscillating splints, couplings, bearings, clutches, spinelles and seals; and in base plates, universal joints and shackles. |
