Fretting Corrosion Panama City FL
Fretting and fretting wear can occur on non-electrical things like bearings, but fretting corrosion is something that is associated more with electrical contacts. Fretting corrosion is the name for a buildup of insulating, oxidized wear debris that can form when there is small amplitude fretting motion between electrical contacts. If you work with automotive terminals, you may have heard folks talking about fretting corrosion. A lot of people know that fretting corrosion isn’t a good thing, but they aren’t sure exactly what it is. Hopefully, the following information will help explain what fretting corrosion is all about.

Fretting Corrosion
January 07, 2010 Fretting and fretting wear can occur on non-electrical things like bearings, but fretting corrosion is something that is associated more with electrical contacts. Fretting corrosion is the name for a buildup of insulating, oxidized wear debris that can form when there is small amplitude fretting motion between electrical contacts. If you work with automotive terminals, you may have heard folks talking about fretting corrosion. A lot of people know that fretting corrosion isn’t a good thing, but they aren’t sure exactly what it is. Hopefully, the following information will help explain what fretting corrosion is all about. Some Definitions “Fretting” is a term to describe a small amplitude rubbing motion between two surfaces. By definition, the amount of relative movement between the contacting surfaces is about 10 to 100 microns for fretting. To put this in perspective, a sheet of paper is about 100 microns thick, so fretting motion is pretty small and hard to see. Vibration and thermal expansion/contraction are the main sources that create fretting motion. Since cars vibrate and can experience some relatively large temperature swings, they are a good source for fretting motion.
