Textured Ti₃SiC₂ by EPD in a Strong Magnetic Field

Abstract:

We present a method for fabrication of textured MAX phase ceramics, particularly, Ti₃SiC₂; by EPD in a strong magnetic field (12T). Ti₃SiC₂ was dispersed in cationic polyelectrolyte-Polyethylenimine (PEI). Addition of 0.3-1dwb PEI resulted in high zeta potential values and suspension was found to be stable and of good fluidity. The optimized suspension parameters for EPD were determined as 10vol% Ti₃SiC₂ and 1dwb PEI in 50 % ethanolic water at pH ~ 7. X-ray diffraction analysis of the textured samples revealed that the preferred orientation of Ti₃SiC₂ grains parallel to the magnetic eld direction was along the a,b-axis. The Lotgering orientation factors on the textured top surface and textured side surface were determined as f _(hk0) = 0.35 and f _(00l) = 0.75, respectively.
