Hartwalzen zur Festigkeitssteigerung wälzbelasteter Funktionsflächen

Abstract

The service life of functional surfaces subjected to rolling loads is limited by fatigue or insuffi cient separation of the rolling partners in the event of inadequate lubrication. These failure mechanisms can be counteracted by hard rolling and thus the introduction of residual compres sive stresses into the border zone, which can, among other things, extend maintenance intervals of production or power generation plants.
