HOW CAN FRETTING BE PREVENTED?
In connector industry terms, “fretting corrosion” relates to a specific type of failure at the separable contact interface, frequently associated with tin finishes. A contact interface that experienced fretting usually exhibits corrosion debris (oxides) due to very small, cyclical wearing motions, often resulting in an undesirable increase in contact resistance. Resolving a fretting issue may include protecting the surface from the environment, or by minimizing the fretting motion. APEX advises on connector design aspects that identify, prevent, or minimize the effects of fretting.
