Title (EN) A METHOD OF MAKING A POLYCRYSTALLINE SUPER HARD CONSTRUCTIONS
(FR) PROCÉDÉ DE FABRICATION D'UNE CONSTRUCTION SUPER-DURE POLYCRISTALLINE
Abstract:
(EN) A method of forming polycrystalline diamond comprised placing a plurality of graphene nano-platelets into a capsule; and subjecting the platelets to a pressure of around 10 GPa to around 20 GPa and a temperature of around 1600 degrees Celsius to around 3000 degrees Celcius to convert the graphene platelets to nano-polycrystalline diamond. There is also disclosed a polycrystalline super hard construction comprising a polycrystalline diamond region comprising polycrystalline diamond material formed according to said method.
(FR) Un procédé de formation de diamant polycristallin consiste à placer une pluralité de nano-plaquettes de graphène dans une capsule; et soumettre les plaquettes à une pression d'environ 10 GPa à environ 20 GPa et une température d'environ 1600 degrés Celsius à environ 3000 degrés Celsius pour convertir les plaquettes de graphène en diamant nanocristallin. L'invention concerne également une construction super-dure polycristalline comprenant une région de diamant polycristallin comprenant un matériau de diamant polycristallin formé selon ledit procédé.
