The influence of heterogenous porosity on silicon nitride/steel wear in lubricated rolling contact [PDF]

open access: yes, 2000
Heterogeneous porosity is detected on the surface and subsurface of hot isostatically pressed (HIPed) silicon nitride spherical rolling elements. The extent of the localised porosity accounts for an area of 6% of the rolling element surface and 4% of the

Failure modes of silicon nitride rolling elements with ring crack defects [PDF]

open access: yes
High quality silicon nitride ceramics have shown some advantages for rolling element bearing applications. In particular hybrid bearings (silicon nitride rolling elements and steel races) have the ability to withstand high loads, severe environments ...
