Abstract

This study introduces a novel method to enhance the rolling contact fatigue life of bearing steel by forming a crease-like oxide layer on the contact surface. This strengthening way is proposed based on the damage mechanism and ultra-high life in dispersion of fatigue life. Different from conventional surface modification pretreatment methods, this oxide layer can be formed through the reaction of the bearing steel surface with lubricating oil under cyclic rolling stress. This oxide layer can make the fatigue life of bearing steel get comprehensive improvement by delaying subsurface microstructure decay and reducing the likelihood of surface initiation failure.

期刊介绍： Tribology is the science of rubbing surfaces and contributes to every facet of our everyday life, from live cell friction to engine lubrication and seismology. As such tribology is truly multidisciplinary and this extraordinary breadth of scientific interest is reflected in the scope of Tribology International. Tribology International seeks to publish original research papers of the highest scientific quality to provide an archival resource for scientists from all backgrounds. Written contributions are invited reporting experimental and modelling studies both in established areas of tribology and emerging fields. Scientific topics include the physics or chemistry of tribo-surfaces, bio-tribology, surface engineering and materials, contact mechanics, nano-tribology, lubricants and hydrodynamic lubrication.
