Different Types of Corrosion
- Recognition, Mechanisms & Prevention

Fretting Corrosion
 

Recognition
   

What is fretting corrosion?  Fretting corrosion refers to the deterioration at the interface between contacting surfaces as the result of corrosion and slight oscillatory slip between the two surfaces.

Fretting corrosion are expected in many tight-fitting parts that are designed not to slip against each other, but in the presence of vibration and pressure fluctuation, these parts do slip against each other such as bolted or riveted parts that vibrate.
  Mechanisms
   

What causes fretting corrosion?

Fretting corrosion is a severe corrosive wear that occurs to heavily loaded surfaces that move only slightly but repeatedly against each other. Fretting corrosion is different from ordinary wear in that it occurs rapidly with little movement.
  Prevention
    How to prevent fretting corrosion? Fretting can be prevented through:
  • Lubricate the surfaces
  • Regularly inspect and maintain the lubrication
