Abstract: An embodiment of a PCD insert comprises an embodiment of a PCD element joined to a cemented carbide substrate at an interface. The PCD element has internal diamond surfaces defining interstices between them. The PCD element comprises a masked or passivated region and an unmasked or unpassivated region, the unmasked or unpassivated region defining a boundary with the substrate, the boundary being the interface. At least some of the internal diamond surfaces of the masked or passivated region contact a mask or passivation medium, and some or ail of the interstices of the masked or passivated region and of the unmasked or unpassivated region are at least partially filled with an infiltrant material.

Abstract: A coated super-hard abrasive comprises a core of super-hard abrasive material, which is typically diamond or cBN based, an inner layer of a metal carbide, nitride, boride, boronitride or carbonitride chemically bonded to an outer surface of the super-hard abrasive material and one or more outer layers of a metal carbide, nitride, boride or carbonitride physically deposited on the inner layer. In the case of a single outer layer, the single outer layer has a composition gradient extending through its thickness, and in the case of more than one outer layer, the composition of each layer is different to provide a gradient of material through the various layers. In the case of several outer layers, each layer may also include a composition gradient.
Abstract translation: 涂覆的超硬磨料包括超硬磨料的芯，其通常为金刚石或cBN基，金属碳化物，氮化物，硼化物，氮化硼或碳氮化物的内层化学键合到超硬的研磨材料的外表面 研磨材料和物理沉积在内层上的金属碳化物，氮化物，硼化物或碳氮化物的一个或多个外层。 在单个外层的情况下，单个外层具有延伸穿过其厚度的组成梯度，并且在多于一个外层的情况下，每层的组成不同以提供通过各层的材料的梯度 。 在几层外层的情况下，每层也可以包括组成梯度。
