Abstract

Le procédé consiste : (a) à préallier un catalyseur métallique avec du carbone, du silicium ou un mélange de carbone et de silicium ; (b) à appliquer ce catalyseur préallié à un substrat de carbone ; (c) à chauffer ce substrat avec du catalyseur préallié appliqué en atmosphère réductrice : (d) à introduire des gaz contenant du silicium et du carbone dans cette atmosphère ; (e) à maintenir le débit de ces gaz ; et (f) à refroidir les trichites de carbure de silicium. Les trichites sont utilisés comme matières de renfort composites pour des métaux, matières plastiques et céramiques.
