Journal ArticleDOI
An Experimental and Theoretical Study of Hybrid Bearing Micropitting Performance under Reduced Lubrication
TL;DR: In this paper, the reduced lubrication performance of hybrid rolling contacts, versus full-steel ones, is studied in detail by means of rolling bearing fatigue experiments and a theoretical micropitting model, and it is found that the large improvement in surface fatigue resistance of hybrid contacts cannot be explained solely on the basis of the unavoidable differences in some of the roughness parameters existing between the full steel and hybrid contacts.
Journal ArticleDOI
Subsurface propagation of partial ring cracks under rolling contact. Part I. Experimental studies
TL;DR: In this article, a modified four-ball machine was used to perform rolling contact fatigue testing and cracks within the contact path were carefully oriented and positioned the same way for all tests.
Journal ArticleDOI
Cavitation erosion in silicon nitride: Experimental investigations on the mechanism of material degradation
TL;DR: In this article, high and low powered ultrasonic vibratory systems were adapted for the study of test samples from three silicon nitride materials used for potential rolling element bearing applications were experimentally studied at different conditions to understand their mechanisms of cavitation erosion.
Journal ArticleDOI
Early stage cavitation erosion within ceramics—An experimental investigation
TL;DR: In this article, six ceramic material types were considered within an experimental investigation to identify the erosion damage mechanisms resulting from cavitation exposure, including Y-TZP-type zirconia, different commercially available silicon nitrides, a high-purity alumina and hardened high-nitrogen stainless steel as reference.
Journal ArticleDOI
Subsurface propagation of partial ring cracks under rolling contact: Part II. Fracture mechanics analysis
TL;DR: In this paper, a boundary element analysis was carried out to identify the main factors governing the propagation of sub-surface cracks and the calculations of the main stress intensity factors (SIF), K I and K II, were made to determine which factors were important for crack propagation.
