Method to reduce oxidation in ceramic composites, method for fabricating a ceramic composite article and an article comprising a ceramic composite protective layer

A method for reducing oxidation in ceramic composites is provided. The method includes depositing (130) a first portion of a silicon carbide (SiC) matrix over at least a portion of an article using a first chemical vapor infiltration (CVI) process, depositing (140) a silicon (Si)-doped boron nitride...

description A method for reducing oxidation in ceramic composites is provided. The method includes depositing (130) a first portion of a silicon carbide (SiC) matrix over at least a portion of an article using a first chemical vapor infiltration (CVI) process, depositing (140) a silicon (Si)-doped boron nitride (BN) layer within at least a portion of the SiC matrix using a second CVI process, and depositing (150) a second portion of the SiC matrix within at least a portion or continuation of the first portion of the SiC matrix using a third CVI process.
