Notes:
In order to clarify the effects of the hybrid surface modification process; a combination ofFine Particle Bombardment (FPB) treatment and nitriding, on the fatigue properties of AISI 4135steel (stress concentration factor: α=2.36), high cycle fatigue tests were carried out with a rotationalbending machine at room temperature. Observations of fracture surfaces and measurements ofhardness and residual stress distributions were carried out to investigate the fracture mechanism andfatigue strength. It was revealed that treating process sequence did affect residual stress distributions.Compressive residual stress generated at the surface of FPB treated specimen after nitriding washigher than that of the one FPB treated before nitriding. It was clarified that the higher the specimenhardness was, the higher compressive residual stress was generated at the surface. Therefore, FPBtreatment after nitriding increased the fatigue strength of steel
