摘要： A tool component comprises an abrasive compact layer bonded to a cemented carbide substrate along an interface. The abrasive compact layer has a working surface, on a side opposite to the interface. This working surface is flat and presents a cutting edge or point around its periphery. A recess extends into the substrate from the interface. The recess has a side wall and a base both of which are located entirely within the carbide substrate. The recess has a portion located in the interface. The area of this portion is at least 25 percent the area of the interface. A material, different to that of the substrate, fills the recess and is bonded to the substrate. This material will typically be abrasive compact of the same type as the abrasive compact layer, or a cemented carbide which has characteristics different to that of the substrate.

摘要： A composite diamond abrasive compact comprises a diamond compact bonded to a cemented carbide support along a compact/carbide interface and is characterised by the carbide support comprising at least two zones, a first zone containing a binder metal content of a predetermined amount, and a second zone extending from the interface to the first zone and having a binder metal content which is substantially lower than that of the first zone. The second zone has a depth or thickness of no more than 0,75 mm. The binder metal content of the second zone increases from the interface to the first zone in a continuous, non-interrupted manner.
摘要翻译：复合金刚石磨料压实体包括沿着紧凑/碳化物界面结合到硬质合金支撑体的金刚石致密体，其特征在于，所述碳化物支撑体包括至少两个区域，包含预定量的粘合剂金属含量的第一区域和第二区域区域从界面延伸到第一区域并且具有基本上低于第一区域的粘合剂金属含量。第二区域的深度或厚度不超过0.75毫米。第二区域的粘合剂金属含量以连续的，不间断的方式从界面增加到第一区域。
