Abstract
Methods for creating coatings composed of a single material or a composite of multiple materials, beginning with ESC to deposit the base layer and then using other methods for the binding step beyond CVI. Also, for certain materials and applications, some pre-processing or pre-treatment of the coating materials is necessary prior to deposition in order to achieve a satisfactory coating. This application discloses methods for pre-deposition treatment of materials prior to ESC deposition. It also discloses methods for post-processing that provide additional functionality or performance characteristics of the coating. Finally, this application discloses certain apparatus and equipment for accomplishing the methods described herein.
