| 摘 要： |
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.
本研究提出了一种新型方法，通过在接触面形成褶皱状氧化层来提高轴承钢的滚动接触疲劳寿命。该强化方式基于损伤机制及疲劳寿命分散化超长寿命的原理提出。与传统的表面改性预处理方法不同，该氧化层可通过轴承钢表面在循环滚动应力作用下与润滑油发生反应而形成。这种氧化层能够通过延缓基体微观结构劣化、降低表面萌生失效的可能性，从而全面提升轴承钢的疲劳寿命。 |
