Title (EN) SUPERHARD CONSTRUCTIONS & METHODS OF MAKING SAME
(FR) CONSTRUCTIONS EXTRA-DURES ET LEURS PROCÉDÉS DE FABRICATION
Abstract:
(EN) A polycrystalline super hard construction has a first region comprising a body of thermally stable polycrystalline super hard material having an exposed surface forming a working surface, and a peripheral side edge, said polycrystalline super hard material comprising a plurality of intergrown grains of super hard material; a second region forming a substrate to the first region, the second region comprising a hard phase and a binder phase; and a third region interposed between the first and second regions, the third region extending across a surface of the second region along an interface. The third region comprises a composite material having a first phase comprising a plurality of non-intergrown grains of super hard material, and a matrix material. The super hard polycrystalline construction further has a fourth region interposed between the second region and the third region, a major proportion of the fourth region comprising one or more components of the binder material of the second region, the fourth region further comprising one or more reaction products between the binder material of the second region and one or more components of the third region.
(FR) L'invention concerne une construction extra-dure polycristalline ayant une première région comprenant un corps de matériau extra-dur polycristallin thermiquement stable ayant une surface apparente formant une surface de travail, et un bord latéral périphérique, ledit matériau extra-dur polycristallin comprenant une pluralité de grains entremêlés de matériau extra-dur ; une deuxième région formant un substrat sur la première région, la deuxième région comprenant une phase dure et une phase liante ; et une troisième région intercalée entre les première et deuxième régions, la troisième région s'étendant sur une surface de la deuxième région le long d'une interface. La troisième région comprend un matériau composite ayant une première phase comprenant une pluralité de grains non entremêlés de matériau extra-dur, et un matériau de matrice. La construction polycristalline extra-dure comprend en outre une quatrième région intercalée entre la deuxième région et la troisième région, une proportion majeure de la quatrième région comprenant un ou plusieurs constituants du matériau liant de la deuxième région, la quatrième région comprenant en outre un ou plusieurs produits de réaction entre le matériau liant de la deuxième région et un ou plusieurs constituants de la troisième région.
