- Hybrid peening is proposed to be applied with objective of improving gears fatigue life with low impact on part manufacturing time. This process consists of an alternative of a conventional dual peening, but with mixing two different media classes in only one stage. A procedure to define media classes’ selection as well as mix distribution is proposed considering the objective of enhancing part lifetime, background of gear failure modes and residual stress theory, by using known residual stress profile prediction models. Results showed that it was possible to reach maximum compressive residual stress target, without being far from its depth desired.
