Fabrication and mechanical properties of Al2O3/SiC/ZrO2 functionally graded material by electrophoretic deposition

► We report the of synthesis Al2O3/SiC/ZrO2 FGM by EPD from a stable suspension based on 2-butanone. ► We study the mechanical and physical properties of Al2O3/SiC/ZrO2 FGM. ► Increasing ZrO2 will show lower hardness, higher toughness and increasing tensile stress. ► Results on Al2O3/SiC composite show that SiC increases the toughness, hardness, and compressive stress.
