Abstract:
(EN) Bearing assemblies that include a plurality of polycrystalline diamond ("PCD") bearing elements, bearing apparatuses including such bearing assemblies, and methods of operating and fabricating such bearing assemblies and apparatuses are disclosed. In an embodiment, the plurality of PCD bearing elements of one or more of the bearing assemblies disclosed herein include at least one first PCD bearing element. At least a portion of the first PCD bearing element exhibits a coercivity of about 125 Oersteds or more and a specific magnetic saturation of about 14 Gauss·cm3/gram or less. The first PCD bearing element includes a bearing surface with at least one groove formed therein. In an embodiment, the plurality of PCD bearing elements also include at least one second PCD bearing element. The second PCD bearing element exhibits a coercivity that is less than and a specific magnetic saturation that is greater than the first PCD bearing element.
(FR) L'invention concerne des ensembles paliers qui comprennent une pluralité d'éléments de palier en diamant polycristallin ("PCD"), des appareils de palier comprenant de tels ensembles paliers, et des procédés de fonctionnement et de fabrication de tels ensembles et appareils paliers. Dans un mode de réalisation, la pluralité d'éléments de palier en PCD d'un ou de plusieurs des ensembles paliers décrits ici comprennent au moins un premier élément de palier en PCD. Au moins une partie du premier élément de palier en PCD présente une coercivité d'environ 125 Oersteds ou plus et une saturation magnétique spécifique d'environ 14 Gauss·cm3/gramme ou moins. Le premier élément de palier en PCD comprend une surface de palier avec au moins une rainure formée à l'intérieur de celle-ci. Dans un mode de réalisation, la pluralité d'éléments de palier en PCD comprennent également au moins un second élément de palier en PCD. Le second élément de palier en PCD présente une coercivité qui est inférieure à celle du premier élément de palier en PCD et une saturation magnétique spécifique qui est supérieure à celle du premier élément de palier en PCD.
