CARBON NANOTUBES REINFORCED ZIRCONIA COMPOSITES FOR ARTFICIAL HIP JOINTS BEARING SURFACES

This research focuses on the properties and capabilities of carbon nanotubes (CNTs) as reinforcing agents in ceramic composite bearing components. The addition CNT to pure ceramics can form composites with much better performance than conventional for various applications. study was started from their use a component total hip arthroplasty damage that occurred after implantation. covers factors cause degradation introduction CNTs new materials widely used sintering method heat pressure parameters during process meet standards manufacture Total Hip Arthroplasty (THA) component. contact buckling behaviors influence friction properties. presence until 20 wt% exhibited improve wear resistance lower increase weight percent. reinforced coating might be capable withstand high load-bearing conditions. Plastic deformation one critical processes mechanism. Other are cracking chemical reaction. microstructures porosity take an important role indicating mechanisms.
