Abstract

Aqueous Electrophoretic Deposition of ZrB2-SiC Nano-composites in Pulsed DC Electric Fields

Yuping Zhang, Xiang Lin, Weiwei Chen and Lu Wang

ZrB2-SiC ultra-high temperature ceramic composites have been considered to be the optimal candidate for using in extreme environments. The present communication for the first time applied aqueous electrophoretic deposition for successfully preparing ZrB2-SiC nano-composites in pulsed DC electric fields. The deposition behavior was investigated based on the influences of applied voltage, duty cycle and frequency. A smooth, uniform and pore-free ZrB2-SiC nano-composite was successfully synthesized. The highest green density of 67.1% was achieved for the nano-composite with the SiC content of 26.7 wt.%. We believe that the present research will open up a new horizon in preparing bulk ceramic composites or composite working parts in industries.
