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 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

This paper presents the results of a thermodynamic study concerning the codeposition of phases of the silicon, boron and carbon system by a classical C.V.D. technique from an initial gaseous mixture composed of methyltrichlorosilane (MTS), boron tric

Development of a nuclear analytical technique for the analysis of ternary compounds (B + C + Si) and application to the optimization of a CVD process

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
