摘要

The effect of the pressure - pulsed chemical vapour infiltration on improving the quality of CMC - parts has besn investigated. In a fabrication process of three - dimensional C/SiC composites, the PCVI was applied as a final densification step for specimens made by a joint process consisting of slurry infiltration and polycarbosilane imprcgnation / pyrolysis. PCVl was carried out in the temperature range of 1323-1423 K using a source gas system of SiC14 - CH4 - H2. The crystalline phases deposited by PCVI varied with temperature, gas concentration and holding time. At 1373 K, a large amount of SiC deposition into the matrix was observed, and the deposition rate was at least twice higher than for the CH3SiCl3 H2 gas system in our previous work. The flexural strength remarkably increased after the PCVI step
