Enhancing the Rotational Bending Fatigue Performance of 20CrMoH via Carburizing and Surface Ultrasonic Nanotechnology
To alleviate the risk of rotational bending fatigue (RBF) failure in 20CrMoH alloy steel, a hybrid surface modification strategy combining carburizing and surface ultrasonic nanotechnology (SUNT) is developed in the present work. The synergistic effects of the combined treatment on surface integrity, residual stres...
