5Route steps
A peened gear is primarily made by Shot Peening. Shot peening blasts the surface with small media to put it in compressive stress, which raises fatigue life. Below is the full route to make a peened gear, the materials it suits, the tolerances to expect and the main design points. The route is free, from the finder.
Step by step
How a peened gear is made
The usual route, raw material to finished part. The amber step is where the peened gear gets its basic shape.
Make the part
Form and finish-machine the peened gear to size first.
Tooling None Tolerance ±0.125mm, to ±0.025mm Lead 1 to 10 days
Clean and mask
Clean the surface and mask the areas that must stay bare.
Shot Peening
Apply the shot peening to the peened gear.
Tooling Low Tolerance minimal Lead days
Post-finish
Seal, cure or re-grind any surface that changed dimension.
Inspection
Check coating thickness, hardness or adhesion.

Cost
What a peened gear should cost
Bombards the surface to induce compressive stress and raise fatigue life on cyclically-loaded parts (springs, gears, shafts).
PER-PART COST vs VOLUME
Per-part cost drops as volume spreads tooling and setup over more parts. The exact figures for a peened gear at your volume, in your currency, are in the dossier.

What does a peened gear cost?
It depends on size, tolerance and volume. As a rough ballpark it starts around $2.5 to 7.2 per part at 1 off and falls with quantity. The dossier gives should-cost at your exact volume and currency. A model estimate, not a quote.
What material is a peened gear made from?
Common choices are (fatigue-loaded steels/alloys).
What is the main process for a peened gear?
Shot Peening. Fatigue-critical parts like springs, gears, shafts and airframe components.
