    摘要: A method for reducing oxidation in ceramic composites is provided. The method includes depositing 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 a silicon (Si)-doped boron nitride (BN) layer within at least a portion of the SiC matrix using a second CVI process, and depositing 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.
