Özet

In this study, wear behavior of ultrasonic impact treated S235JR steel was investigated. Samples were peened for different times (5, 15 and 30 minutes) by ultrasonic impact treatment. It was found that triple layers (nanocrystallization, plastic deformation and residual stress) formed on the treated surface. The thickness of the layers treated samples increased with increasing treatment time. It was also determined that surface roughness of treated samples decreased with increasing treatment time. All treated samples have significant surface hardness. Nanocrystallization layer on top of the treated surface has the highest hardness values in comparison with the hardness of the other layers. The treatment increases not only surface hardness, but also wear resistance of all treated samples. The maximum wear resistance was observed for the 30 min treated samples due to the high hardness and thickness of the nanocrystallization layers.
