Effect of carburizing on fatigue life of highstrength steel specimen under push-pull loading
Original language description
Many articles are dedicated to effect of surface layer on fatigue life. However, most of these articles are dedicated to the steels with nitride layer and only small number of papers is dedicated to the carburizing. Results of extended experimental investigation of fatigue resistance of plasma-carburized specimens made of the lowalloy high-strength steel are presented. The specimens were subjected to push-pull loading of different R-ratios. The application of plasma carburizing can lead to about 25% increase in the fatigue resistance in the high cycle region (over 105 cycles). On the contrary, in the case of low cycle fatigue often has a negative effect on the service life.
