FABRICATION OF SiC_f/SiC-ZrB_2 COMPOSITES BY A HYBRID PROCESS OF ALTERNATING CURRENT ELECTROPHORETIC DEPOSTION (AC-EPD) AND HOT PRESSING

摘要

In this study, we report on the fabrication of continuous SiC fiber-reinforced SiC-ZrB_2 ceramic matrix composites (SiC_f/SiC-ZrB_2) through a hybrid process of slurry impregnation by electrophoretic deposition and hot pressing. An effective impregnation of the slurry into the fine voids of fiber preform is essential to fabricate dense composites, which was achieved by a simple, fast and efficient electrophoretic deposition method.
