    • A method of making a super-hard article comprising a super-hard structure (14) bonded to a substrate (18), the super-hard structure comprising a sintered plurality of super-hard grains. The method includes providing raw material powder suitable for sintering the super-hard structure. The raw material powder is combined with organic binder material in a liquid medium to form paste. The content of the raw material powder is more than 60 and less than 85 mass per cent of the paste and the composition of the paste is such that it has a shear rate of at most 25 inverse second (s-1). A substrate assembly is provided, which comprises the substrate, having a formation surface area configured for forming a boundary of the super-hard structure, the substrate comprising a recess coterminous with the formation surface area. The paste is extruded into contact with the formation surface area to provide a paste assembly. The paste assembly is heat treated to remove the binder material and provide a pre-sinter assembly. The pre-sinter assembly is subjected to a pressure and temperature sufficient to sinter the raw material powder and transform it into the super-hard structure bonded to the substrate at a boundary coterminous with the formation surface area. The super-hard material is diamond or cubic boron nitride.
    • 一种制造超硬制品(例如工具或麻花钻)的方法,所述超硬制品包括结合到基底18(其可以是硬质合金)的超硬结构,所述超硬结构包括烧结的多个超硬 晶粒(如多晶金刚石,PCD或多晶立方氮化硼,PCBN)。 该方法包括提供适用于烧结超硬结构的原材料粉末。 原料粉末与有机粘合剂材料在液体介质中结合以形成糊剂。 原料粉末的含量在膏体的60-85质量%与膏体的组成之间是这样的,即其具有至多25秒(s-1)的剪切速率。 衬底组件具有形成表面区域,该形成表面区域被配置用于形成超硬结构的边界,衬底还包括与形成表面区域相连的凹槽16。 将糊剂挤出与地层表面区域接触以提供糊剂组件。 对糊料组件进行热处理以去除粘合剂材料并提供预烧结组件。 预烧结组件经受足够的压力和温度以烧结原材料粉末,并将其转化成粘合到基材的超硬结构,其边界与地层表面区域相连。
