Title (EN) METHOD OF PREPARING COMPLEX-SHAPED CERAMIC-METAL COMPOSITE ARTICLES AND THE PRODUCTS PRODUCED THEREBY
(FR) PROCEDE DE FABRICATION D'ARTICLES COMPOSITES DE FORME COMPLEXE CONTENANT DES CERMETS, ET ARTICLES AINSI OBTENUS
Abstract:
(EN) The invention is a complex-shaped article, comprising an article prepared by joining at least one multi-phase ceramic-metal part and at least one shaped part of another material, wherein the theoretical density of the at least one ceramic-metal part is greater than 80 percent. In another aspect, the invention is a process for preparing complex-shaped articles, comprising: (a) forming at least one ceramic-metal part; (b) forming at least one shaped part of another material; and (c) joining the at least one shaped ceramic-metal part with the at least one shaped part of another material such that a complex-shaped article is formed. The invention is a less costly and time-consuming process for preparing complex-shaped composite articles wherein the articles are formed of two or more selected materials wherein one of the materials is a ceramic-metal composite.
(FR) L'invention porte sur un article de forme complexe obtenu par réunion d'au moins une pièce de cermet en phase multiple et d'au moins une pièce moulée d'un autre matériau, la densité théorique de la ou des pièces de cermet dépassant 80 %. L'invention porte également sur un procédé de fabrication d'articles de forme complexe consistant à: (a) mouler au moins une pièce de cermet; (b) mouler au moins une pièce d'un autre matériau; et (c) réunir la ou les pièces moulées de cermet à la ou les pièces moulées de l'autre matériau pour former un article de forme complexe. Ladite invention constitue un procédé moins onéreux et moins long de préparation d'articles de forme complexe faits de deux matériaux au moins dont l'un est un cermet.
