Electrophoretic deposition prepared yttria as interface of tungsten fiber reinforced tungsten composites
As the interface material for tungsten fiber reinforced tungsten composites (Wf/W), yttrium oxide thin films were prepared via an electrophoretic deposition (EPD) method in this study. The yttrium oxide dispersion is optimized based on its Zeta potential. The coating process was performed on the tungsten weaves (anode), and stainless steel was used as the counter electrode (cathode). The coating structure obtained from the EPD process was homogeneously distributed on all the fibers of the weave, but possess a porous structure. In addition, to optimize the coating process, the voltage influence on the coating process is demonstrated. Using the EPD prepared yttria interface, Wf/W is produced based on a chemical vapor deposition process. Initial mechanical test shows a promising property with extrinsic toughening mechanisms and high damage resilience.
