Increasing the fatigue characteristics of medium-carbon steels for the manufacture of transmission parts of forest machines
The paper assesses the effect of surface hardening by carbonitration on the fatigue characteristics of samples from medium-carbon steels (steel 40, steel 38HA, steel 40HFA). It was found that the greatest increase in fatigue characteristics was observed when processing samples for 3 to 4 hours. The greatest increase in fatigue characteristics was observed for steel 40.
