摘要:
Roller cutters comprise a diamond-bonded body joined to an infiltration substrate. An extension is joined to the substrate and includes first section having a diameter sized the same as the substrate, and an integral second section having a diameter smaller than the substrate. The extension is joined to the substrate during an HPHT process. The first section has a thickness greater than that of the infiltration substrate. The second section has an axial length greater than the combined thickness of the substrate and the first section. The extension has a strength and/or toughness greater than the substrate as a result of its material composition, e.g., the amount of binder phase material and/or the size of hard phase material. The roller cutter is rotatably disposed within a pocket internal cavity, wherein the pocket is attached to a drill bit.
摘要(中):
滚子切割机包括连接到渗透基底的金刚石结合体。 延伸部连接到基板,并且包括具有与基板相同尺寸的直径的第一部分和具有小于基板的直径的整体的第二部分。 在HPHT过程中,延伸部分与基底相连。 第一部分的厚度大于浸渗底物的厚度。 第二部分的轴向长度大于基板和第一部分的组合厚度。 由于其材料组成,例如粘结相材料的量和/或硬相材料的尺寸,延伸部具有大于基材的强度和/或韧性。 辊切割器可旋转地设置在袋内部空腔内,其中袋被附接到钻头。
