Micro and Nano-Scale Surface Texturing: An Application in Ceramic-on-Ceramic Artificial Joint Materials
Friction induced squeaking in artificial hip joints with ceramic-on-ceramic bearing materials is a recognized clinical complication. In this study, micro and nano-scale surface texture is designed and applied on the ceramic artificial joint materials by laser fabrication. The biotribological and acoustic performance of surface textured ceramic-on-ceramic wear couples is investigated. Experiments are carried out via a biotribo-acoustic system developed for artificial joints, through which, both tribological and acoustic data can be acquired synchronously. ZrO2 pins and discs are used as wear couples, and lubricated in biomimetic synovial fluids. Results show that certain surface texture on the ZrO2 samples can help to reduce sound power emission, as well as improve the tribological performance. High fundamental frequency can be avoided in the wear testing of surface textured samples. Material is protected and retained within the sliding range of texture. Micro and nano-scale surface texturing provides a potential solution to the squeaking problem in ceramic artificial joints.
