This research aims to evaluate how multifunction cavitation treatments affect the residual stress and hardness of carburized steel.
Examined the effects of multifunction cavitation (MFC) and energy-intensive multifunction cavitation (EI-MFC) on carburized steel.
Conducted fatigue tests at a stress ratio of -1 to assess performance under low stress conditions.
Both MFC and EI-MFC treatments increased compressive residual stress and hardness in carburized steel.
EI-MFC resulted in higher residual stress and deeper affected layers compared to MFC.
Fatigue tests showed improved performance under low stress amplitude after the treatments.
