Contour Induction Hardening Method has been in the limelight as a new possible case hardening method that causes considerably small distortion and high compressive residual stress. Recently, automobile and other companies are actively engaging in the research of gear surface improvement, such as higher compressive residual stress and hardness by refurbishing the Shot Peening Method. Under these circumstances, our researchers applied the compound surface refining method to gears using both the Contour Induction Hardening Method and the Double Shot Peening Method and conducted a research of modified surface characteristics and fatigue strength. The results showed that the fatigue strength of gears processed by the compound surface refining method achieved 36% better than that of the gears processed only by the Contour Induction Hardening Method.
