摘要: AbstractMetallographic examination performed on a number of micropitted gears has revealed microstructural features similar to those reported in the literature fatigued bearings, namely, dark etching regions and white bands. In addition, new type fatigue-induced constituent was observed close surface below asperities referred as plastic deformation region. Finally, it is shown that initiation propagation cracks leading formation micropits are related phase transformations mentioned previously.
