Abstract
In order to investigate the effect of radical nitriding on fatigue behavior of high-strength steels, very long life fatigue tests were carried out for two kinds of steels, 18Ni Maraging steel and SUJ2 bearing steel, by using conventional and ultrasonic machines, respectively. It was shown that radical nitriding played the principal role in the subsurface crack initiation. Fatigue strength of Maraging steel appears to be significantly enhanced by radical nitriding, however, radical nitriding has a destructive effect on the fatigue behavior of SUJ2 steel.
