Infiltration of a 3-D Fabric for the Production of SiC/SiC Composites by Means of Electrophoretic Deposition
Electrophoretic deposition (EPD) was used to infiltrate 2D and 3D SiC fabrics with SiC submicron particles with the aim to verify the potential of the technique for the fabrication of dense SiC/SiC composites. Bulk SiC deposits were first prepared from aqueous suspensions with different dispersants using cathodic and anodic deposition. The most suitable composition of the suspensions and the conditions for the infiltration were determined on the basis of the analysis of green parts formed. Using a specially designed EPD cell a relatively high packing density of SiC particles in infiltrated 2D and 3D SiC-fiber fabrics was achieved.
