Microstructural degradation of bearing steels
… most fundamental aspects of fatigue damage in bearings steels through critical experiments, in particular whether damage in the form of cracks precedes hard “white-etching matter" formation, which is carbon supersaturated nanoscaled ferrite. Heat treatments have been designed to create four …

Microstructural alterations in bearing steels under rolling contact fatigue
The formation of microstructural alterations in bearing steels under rolling contact fatigue (RCF) is systematically studied. A literature review summarizes current understanding in this field, leading to the key to the formation of these microstructural features being carbon redistribution as a …

Hydrogen trapping in bearing steels: mechanisms and alloy design
… rich environment, applications such as rolling bearings display a significant decrease in alloy strength and accelerated failure due to rolling contact fatigue. In spite of these problems being well recognised, there is little understanding as to which mechanisms are present in hydrogen induced …

An Experimental Evaluation of Micro-pitting Performance of Two Bearing Steels
… load on micro-pitting performance of two typical bearing steels. Case hardened roller specimens made of alloy 9310 and through-hardened roller specimens made of alloy 485-2 are procured. Test matrices are defined according to the Latin Hypercube Space Filling Design of Experiment approach and …

Mechanisms of microstructural damage during rolling contact fatigue of bearing steels
Bearings are employed in a number of applications under extremely demanding conditions. During long operation times, the material undergoes rolling contact fatigue where microstructural damage manifests as dark-etching regions and white-etching areas, which display different properties from the …

Analysis of the Tribological Behaviour of Stainless and Ball Bearing Steels Sliding in the Presence of Sulphur Extreme-Pressure Additives
… The tribological behaviour of stainless and ball bearing steel were studied under extreme pressure and/or anti-wear lubrication conditions in the presence of sulphur and sulphur containing additives, in order to compare the wear behaviour of the AISI 420 stainless steel with the SAE 52100 steel, …

Rolling contact fatigue of silicon nitride.
… has traditionally been used as rolling contact bearing material owing to its superior performance compared to bearing steels. Its successful application as a bearing element has led to the development of Silicon Nitride in other rolling contact applications in the automotive industry and the …
