Electrophoretic deposition of mullite in a continuous fashion utilizing non-aqueous polymeric sols
- Wright Laboratory, Wright-Patterson AFB, OH (United States)
The feasibility of depositing mullite via electrophoretic deposition (EPD) onto a 2-d substrate, such as Nicalon{trademark} cloth, was determined in this preliminary study. Mullite coatings were deposited onto a C-coated Nicalon{trademark} cloth using a polymeric precursor. XRD data suggest that phase separation of the sol does not occur upon drying and subsequent thermal treatment of the sol. XRD also indicates an amorphous {r_arrow} crystalline transition between 800 and 900{degrees}C. The coatings appeared to be fairly uniform throughout the cloth cross-section, on the order of 250nm thick, and displayed a minimal amount of bridging. A large amount of 5 nanometer-sized porosity was uniformly distributed throughout the coating.
