Improvements in material quality, manufacturing methods, and implant design have resulted in a drastic reduction of the incidence of such failures, so that modern ceramic bearings are safe and reliable if used with components of proven design and durability.
The developed finite element model can be used for the analysis of the wear mechanisms of bearings and the prediction of the service life of bearings.
Nonetheless, patients considering ceramic-on-ceramic bearings should be counseled with regard to this phenomenon.
This study provides information for the bearing acoustic characteristics, and is relevant for the design and operation of ceramic bearings.
The study results demonstrate the validation of the bearing models and elucidate different responses between mechanical and ceramic auxiliary bearings during contact events.
The new methodology, by providing a direct account of the survival probability of the ceramic-steel interface gives a better representation of the expected performance of hybrid bearings, opening new opportunities for the reliable use of this type of bearing in modern machinery.
