Abstract

L'invention concerne une technique de fabrication de matériaux superdurs (MUS) et notamment la synthèse de diamants, de nitrure de bore, de matériaux polycristallins et composites sur la base de ces derniers, la fabrication de poudres et d'instruments contenant ces matériaux et utilisés notamment pour fabriquer des outils abrasifs ou coupants. L'invention vise un procédé permettant la fabrication de matériaux superdurs qui assurerait un rendement élevé de MUS à des températures plus basses et à une pression peu élevée, sans catalyseurs. Le procédé de l'invention est caractérisé en ce que l'on utilise en tant qu'additifs de formation de cristaux une poudre ultradispersée d'un matériau ayant une structure cubique. Dans un mode de réalisation, on utilise en tant que poudre ultradispersée d'un matériau ayant une structure cubique une poudre ultradispersée de diamant. La synthèse du MUS (diamant et/ou c-BN) est conduite à des températures extrêmement basses (inférieures de 800 à 1000 à celles nécessaires lors de la synthèse catalytique) et à une pression relativement basse. Le rendement en terme de MUS se trouve augmenté jusqu'à 96-100 % sans être accompagné d'additifs étrangers, ce qui permet de fabriquer des outils ayant une structure et une caractéristique désirées. L'invention permet d'économiser sensiblement l'énergie et les matériaux coûteux.
