Abstract: front page image
(EN)Thermally stable polycrystalline constructions comprise a diamond body joined with a substrate, and may have a nonplanar interface. The construction may include an interlayer interposed between the diamond body and substrate. The diamond body preferably has a thickness greater than about 1.5 mm, and comprises a matrix phase of bonded together diamond crystals and interstitial regions disposed therebetween that are substantially free of a catalyst material used to sinter the diamond body. A replacement material is disposed within the interstitial regions. A population of the interstitial regions may include non-solvent catalyst material and/or an infϊltrant aid disposed therein. The diamond body comprises two regions; namely, a first region comprising diamond grains that may be sized smaller than diamond grains in a second region, and/or the first region may comprise a diamond volume that is greater than that in the second region.
(FR)La présente invention concerne des constructions polycristallines thermiquement stables qui comprennent un corps en diamant relié à un substrat et qui peuvent avoir une interface non plane. La construction peut comprendre une couche intermédiaire disposée entre le corps de diamant et le substrat. Le corps de diamant présente de préférence une épaisseur supérieure à 1,5 mm environ et comprend une phase matricielle constituée de cristaux de diamant liés entre eux, ainsi que des zones interstitielles disposées entre ces derniers, lesquelles sont sensiblement exemptes de matériau catalyseur utilisé pour fritter le corps de diamant. Un matériau de remplacement est disposé dans les zones interstitielles. Un ensemble de zones interstitielles peut comprendre un matériau catalyseur non-solvant et/ou un matériau infiltrant disposé entre lesdites zones. Le corps de diamant comprend deux zones. La première zone comprend des grains de diamant dont les dimensions peuvent être plus petites que les grains de diamant présents dans une seconde zone et/ou la première zone comprend un volume de diamant supérieur à celui du diamant dans la seconde zone.
