Fretting corrosion and false brinelling.

Fretting corrosion and false brinelling.

Fretting corrosion and false brinelling.

(OP)
Does anyone know if there is a relationship between fretting corrosion and contact pressure in two microscopically sliding oscillating surfaces ?

I am trying to establish some load limits for ball bearings where there is a tendency to 'false brinell' due to load fluctuations when the brg is not rotating. The application is a wind turbine blade brg.

Some manufacturers have suggested that the relationship resembles a bending fatigue S-N curve, ie. below a certain contact stress level f/b will not occur regardless of how many movement cycles are made. I dont really believe this is the case. I think low contact stresses will create the same level of damage given sufficient cycles. Any thoughts or experience ?

RE: Fretting corrosion and false brinelling.

May I suggest you read chapter 15 on Engineering Tribology by Stachowiak and Batchelor, Elsevier Tribology Series, 24. The heading is "Fretting and Minor Wear Mechanisms". It includes fretting wear, melting wear, fretting due to electrical effects, diffusive wear, and impact wear. It gives useful references, and offers methods for controlling fretting. Good luck.
