Synthesis, microstructural and tribological characterization of calcined nano-bioceramic α- al2o3, sintered at different temperatures
TypeCommunications sans actes
The current research was undertaken to study the improvement of the tribological behavior of nanocrystalline bioceramic, α-alumina sample, produced by the calculations of gibbsite at different temperatures (300 to 1200°C), followed by uniaxial pressing, sintering and HIP treatment. The improved friction and wear resistance is attributed to the fine microstructure of the sample calcined at 1400 °C.
