PROCESS FOR THE ANTI-OXIDATION PROTECTION OF A MATERIAL WHICH, AT LEAST ON THE SURFACE, IS MADE OF A CERAMIC FORMED BY A COMPOUND OF SILICON, AND MATERIAL AS OBTAINED BY THE PROCESS. |
| abstract |
An intermediate layer not containing silicon is formed between the surface of the ceramic formed by a silicon compound (in particular SiC or Si3 N4) and the outer layer based on silica. The intermediate layer is made of alumina or an alumina precursor (for example AlN) in order to constitute a reaction barrier between the silicon compound and the silica of the outer layer and to trap silica possibly formed by oxidation of the compound. silicon. Thus, an anti-oxidation protection is achieved, with a glassy outer layer based on silica, which is effective both under conditions corresponding to the active oxidation range of the silicon compound and under conditions corresponding to the passive oxidation range. |
