Influence on Shot Peening of Surface Durability of Plasma Case Hardened Sintered Powdered Metal Gears

15 November 2023

“In order to investigate the influence of shot peening on the
surface durability of sintered powder metal gears, the plasma
case-hardened sintered powder metal rollers and gears shotpeened
with different condition were fatigue-tested under a
sliding-rolling contact condition.
The hardness, the compressive residual stress and the surface
roughness of the rollers and gears increased by the shot
peening.”
