Fretting Corrosion and Its EffectsWhen converting to a self-lubricating bearing, the external lubricant film is removed from the bearing load zone. This allows contact between the bearing and the shaft. This contact can cause fretting corrosion under the following conditions:
Examples of fretting corrosion causes
| Motion | Example |
| Small angles of oscillation | Toggle linkage |
| Small relative motion | Linear movement of a shaft in a shock absorber |
| Vibration | Torsional vibration from a diesel engine crank shaft or an unbalanced electric motor |
| Cyclic loading | Variable speed belt drives |
Fretting Corrosion SolutionsA hard, corrosion resistant wear surface will minimize fretting corrosion. Several processes have been used to eliminate fretting corrosion as follows:1. Polished hard chrome plating .0003/.0005 inches thick.2. Electroless nickel plating .0003/.0005 inches thick.3. Melonite QPQ heat treatment.
