THE USE OF SOME SURFACING PROCEDURES FOR INCREASE OF FATIGUE STRENGTH OF FRETTING LOADED MACHINERY PARTS
Original language description
The effect of some methods of surface treatment on fatigue strength under the fretting conditions was investigated in EA1N normalized carbon steel with 0,4% C and in EA4T quenched and tempered low alloy CrMo steel. There were applied surfacing methods creating favorable compressive stresses in surface layer and, in some cases, an increased hardness of surface. To obtain data on the effect of work-hardened surface by shot peening, ion-nitriding and ion-carbonitriding on the life-time of fretting fatigueloaded parts, specially instrumented fatigue tests under conditions of fluctuating loading with fretting were performed. The procedures of surfacing as well as typical parameters characterizing the surface layers are described in detail. Fatigue limits relating to 107 cycles were evaluated from the fatigue curves. The results of fatigue tests of surface treated bars are compared with those obtained on bars without surfacing. Applied types of surfacing had an important ? and mostly very f
