Effect of Whisker Content on Mechanical Properties and Microstructure of Hydroxyapatite-SiCw Composite Bioceramics
Theory calculation result indicates that the maximal critical content of SiCw in hydroxyapatite-SiCw composite bioceramics is 23.7%. Hydroxyapatite-SiCw composite micropowder was synthesized using in-situ composite method, and hydroxyapatite-SiCw composite bioceramics with different content of SiCw were produced by hot pressing sintering method. The microstructures of the materials were analyzed by SEM, and the mechanical properties were tested. The results show that the mechanical properties of composite material are the best when the whisker content is 20~23.7%.
