Fretting Corrosion
Fretting Corrosion - deterioration at the interface between contacting surfaces as the result of corrosion and slight oscillatory slip between two surfaces. [1]
Fretting Corrosion involves the degradation of materials under load that are experiencing vibration. It produces pits, oxide detritus, and damage to the metallic interface - and may be viewed as wear that has been aggravated by corrosion. The metallic particles produced by wear oxidize and behave as additional abrasives. Although this form of degradation is seen in both dry and humid air, increased humidity accelerates the process. Machinery may seize up as a result of Fretting Corrosion. There is no obvious amplitude minimum required for fretting to start, and oscillations may only be on the order of microns.
