METHOD OF PROCESSING A BODY OF POLYCRYSTALLINE DIAMOND MATERIAL

A method of processing a body of polycrystalline diamond (PCD) material having a non-diamond phase comprising a solvent catalyst material includes leaching an amount of the solvent catalyst material from the body of PCD material by exposing at least a portion of the body of PCD material to a leachin...

Beschreibung
Zusammenfassung:	A method of processing a body of polycrystalline diamond (PCD) material having a non-diamond phase comprising a solvent catalyst material includes leaching an amount of the solvent catalyst material from the body of PCD material by exposing at least a portion of the body of PCD material to a leaching mixture in aqueous or vapour form, the leaching mixture having a molar concentration of between around 4M to around 9M and including hydrofluoric (HF) acid, and any one or more of hydrochloric (HCI) acid, nitric (HNO3) acid, sulfuric (H2SO4) acid, and/or phosphoric (H3PO4) acid as well as water. Un procédé de traitement d'un corps de matériau diamant polycristallin (PCD) ayant une phase non diamant comprenant un matériau catalyseur de solvant comprend la lixiviation d'une quantité du matériau catalyseur de solvant du corps de matériau PCD par exposition d'au moins une partie du corps de matériau PCD à un mélange de lixiviation sous forme aqueuse ou vapeur, le mélange de lixiviation ayant une concentration molaire comprise entre environ 4 M et environ 9 M et comprenant de l'acide fluorhydrique (HF), et un élément quelconque ou plusieurs éléments parmi de l'acide chlorhydrique (HCI), de l'acide nitrique (HNO3), de l'acide sulfurique (H2SO4), et/ou de l'acide phosphorique (H3PO4), ainsi que de l'eau.
