摘要
Is applied on the surface of the part to be treated in a liquid composition containing a ceramic precursor polymer and a solid filler refractory. After crosslinking, the polymer is transformed into ceramic by heat treatment and a ceramic deposit is then formed by chemical vapor infiltration. Before the step of chemical vapor infiltration, the surface of the piece is cut away in order to return to the initial geometry of the composite material part, so as to form, by chemical vapor infiltration, a deposit which closes the microporosity to the surface of the piece cut away,....
