These micromovements wear down through the metal coatings into the base material that then becomes oxidized. Fretting and Fretting Corrosion. Condition Cause Solution; Fretting surfaces wear producing red rust colored particles that form hollows. On the raceway surface Fretting corrosion is defined as the combination of fretting wear and corrosion (mainly due to oxidation). Fretting wear and oxidation can affect most metal types but tin-plated electrical contacts are particularly susceptible to fretting problems. Tin is quite soft and a thin oxide layer can be quickly formed.

Fretting corrosion is the result of micromotion caused by vibration and/or thermal expansion due to heating or cooling cycles. These micromovements wear down through the metal coatings into the base material that then becomes oxidized.

Fretting corrosion

Fretting is commonly combined with corrosion, a wear mode known as fretting corrosion. Due to rupture of the material and formation of debris, fresh surface is exposed to air which subsequently is getting oxidized (depending on the inertness of the material). In case of steel, the iron oxide is very hard and thus acts as an abrasive.

Fretting corrosion can reduce the endurance limit of steels to as little as 18% of their original values. The greatest reduction in fatigue strength occurs when the fretting process AND cyclic stressing are applied simultaneously. Fretting corrosion occurs when there is a relative movement between a bearing ring and shaft or housing because the fit is too loose. The small wear particles oxidize and areas of rust appear on the outer surface of the outer ring or the bore of the inner ring.

Fretting wear and oxidation can affect most metal types   Fretting corrosion is primarily a surface damage phenomenon occurring as a result of small cyclic movements between two materials caused by cyclic loading. Apr 15, 2019 Fretting corrosion is often seen on external bearing surfaces (bore, outer diameter surfaces, and side faces) and the degree of fretting corrosion  Fretting surfaces wear producing red rust colored particles that form hollows.
