English

Subject field(s)
  • Deterioration of Metals
  • Chemistry
DEF

A combination of corrosion and mechanical-wear effects.

OBS

Many metals and alloys depend upon surface films or corrosion products for corrosion resistance. If these surface layers are removed, active and rapid corrosion occurs. Erosion corrosion is often encountered under conditions of high velocity, turbulence, impingement, and solids in suspension.

French

Domaine(s)
  • Altération des métaux
  • Chimie
DEF

Phénomène résultant de l'action conjuguée de la corrosion et de l'érosion.

OBS

On rencontre ce phénomène lorsque le milieu d'attaque contient en suspension une phase liquide ou solide (et que son écoulement est turbulent). Le choc des particules en suspension sur le matériau détruit le film protecteur et accélère le processus.
