METHOD FOR CHEMICAL INFILTRATION IN THE GAS PHASE FOR THE DENSIFICATION OF POROUS SUBSTRATES WITH PYROLYTIC CARBON |
摘要 |
<p>A method of densifying a porous substrate with pyrolytic carbon includes loading the substrate into an oven, admitting a reaction gas mixture to the oven, extracting an effluent gas from the oven, and recycling components of the effluent gas into the reaction gas mixture. The reaction gas mixture contains a pyrolytic carbon precursor gas together with a vector gas. The effluent gas contains residual components of the reaction gas mixture together with reaction products, including hydrogen. The recycling is performed after eliminating heavy hydrocarbons contained in the effluent gas.</p> |
