概要

Plain fatigue and fretting fatigue tests of dies steel SKD61 with radical nitriding were carried out. Plain fatigue strength of the specimen with radical nitriding was a little higher than that of the specimen without nitriding at high the stress levels. The fatigue cracks in both materials were initiated from surface in the low stress region and inside in the high stress region. On the other hand, fretting fatigue strength of the steel with radical nitriding was significantly high compared to that of the steel without nitriding. The low tangential force coefficient of the specimen with radical nitriding will be one of the main reasons for excellent fretting fatigue resistance.
