2DSiC SiC composites have been elaborated with BN interphases of different thicknesses which were deposited on treated 1 Nicalon™ fibers by isothermal-isobaric chemical vapor infiltration from BCl3NH3H2 mixtures. Their mechanical behavior

International audience; 2D SiC/C(B)/SiC composites were prepared by CVI. The C(B) interphase is made of five successive C(B) layers with increasing boron content from the fibre to the matrix. This composition-graded interphase leads to good mechanica

The results of a thermodynamic and experimental study concerning the codeposition of three elements — silicon, boron and carbon — by a classical C.V.D. technique in a hot-wall reactor are reported. The thermodynamic approach has been described in

The oxidation behaviour of two- and three-dimensional C/SiC protected by a chemicalvapour-deposition (CVD) ceramic coating was studied. The elements used to achieve the surface protection were silicon, boron and carbon, preferably forming SiC, B or B

The oxidation behavior of protected 2D or 3D carbon/carbon composites is studied. The best results are obtained with a C/C material covered by a coating composed of three layers deposited by chemical vapor deposition: a first layer of SiC, a second o

Composites (C/C or C/Si), have a rather poor resistance to oxidation. Coatings made out of ternary compounds (B + C + Si) of various compositions, can provide some protection. These coatings can be obtained by CVD. However, this process has to be opt
