摘要：A system and method for forming a porous ceramic preform is provided. The

method may include forming a stacked powder structure including a binder layer and a

powder layer on the binder layer. The binder layer may be formed by depositing a binder

with a spray nozzle on a substrate. The powder layer may be formed by depositing a

powder on the binder layer. The porous ceramic preform may be formed by heating the

stacked powder structure to pyrolyze the binder. The porous ceramic preform is

configured to be infiltrated by a molten material. The substrate may comprise a ceramic

fiber preform. After melt infiltration of the porous ceramic preform and the ceramic fiber

preform, a densified ceramic feature having a predetermined geometry may be formed

on a ceramic matrix composite (CMC) component.
