Fabrication and mechanical properties of Al2O3/SiC/ZrO2 functionally graded material by electrophoretic deposition
This study describes the synthesis of Al2O3/SiC/ZrO2 functionally graded material (FGM) in bio-implants (artificial joints) by electrophoretic deposition (EPD). A suitable suspension that was based on 2-butanone was applied for the EPD of Al2O3/SiC/ZrO2, and a pressureless sintering process was appl...
