Fretting corrosion accelerates crevice corrosion of modular hip tapers.
Quantification of weight loss of implant due to fretting corrosion was found to be directly proportional to the load transmitted across the surfaces, the number of cycle fretted and amplitude of stresses.

Capable of being close-coupled with standard NEMA and metric IEC frame motors, the patented SWIFT motor connection system eliminates fretting corrosion.
Also, the machine spindle is protected from fretting corrosion, the repeatability of automatic tool change is improved, and even Z-axial movement during high speed rotation is eliminated since the face contact prevents the toolholder from being pulled up into the machine spindle.
The stainless steel band exceeds all current gripping application requirements, maintains dimensional integrity and reduces fretting corrosion.
When used to secure bearings, bushings, gears and cylindrical assemblies into housings or onto shafts, Loctite 638 and Loctite 648 retaining compounds allow higher load transmission and uniform stress distribution, while also eliminating fretting corrosion.

If one bearing ring is made loose on its shaft to accommodate thermal expansion, fretting corrosion and creep are likely to damage the shaft, making dismounting difficult and restricting axial freedom.
This enables all four bearing rings to be mounted with an interference fit that eliminates fretting corrosion and creep.
Fretting corrosion is an interrelated oxidation and wear process that is caused by microscopic axial movement of a bearing outer ring relative to its housing or a bearing inner ring relative to its shaft.
Nyosil-M25UV prevents or retards fretting corrosion on tin-lead crimp connectors for underhood applications, where the lubricant must survive 150(degrees)C.
