Component Serviceability

Premature wear of a surface finish should be visually checked for:

  • Abrasive wear;

  • Corrosion and oxidation;

  • Erosive wear;

  • Fretting;

  • Surface fatigue.

Examples

  • Taper - to become gradually smaller toward one end.

  • Wear - the continuing loss of material from the surface of a solid body.

  • Ovality - the difference between the maximum and minimum dimensions of the overall diameter.

The following illustration measures a crankshaft as an example.
