Laser Peening Application Review: Crankshafts and Camshafts

Objective

Improving the fatigue performance of rotating automotive engine components.

Common Material(s)

Cast iron
1045 – 1060 steel
15xx steel
4140

Surface hardened journals and lobes (induction hardened, carburized, etc.)

Common Failure Mechanisms

Rolling contact fatigue (spalling/flaking)
Bending/Torsion Fatigue
Surface wear/abrasion

The Costs of Failure

When looking at the overall cost of a component failure, there are many important aspects in addition to the part cost itself.  Some costs are quantifiable with expected dollar values. Others are more abstract, but can do significant damage to a company or brand. Here are just a few items to consider:

Cost of replacement part
Cost of labor to replace part
Lost time due to maintenance/replacement
Reputation damage/Unhappy customers
Damage to future sales
Property damage/Bodily injury/Loss of life
