摘要:
Thermally stable polycrystalline constructions comprise a body having a polycrystalline ultra-hard phase and a plurality of empty voids. A population of the voids can be filled with a reaction product. The body is substantially free of a catalyst material. The construction comprises a first support member attached to the body by a first braze material. A second support member is attached to the body and the first support member by a second braze material. The construction may include a third support member attached to the body that is integral or separate from one of the other support members. The braze materials used to attached the support members can be the same or different, as can be the materials used to form the different support members.
摘要(中):
热稳定的多晶结构包括具有多晶超硬相和多个空隙的主体。 空隙的群体可以填充反应产物。 主体基本上不含催化剂材料。 该结构包括通过第一钎焊材料附接到主体的第一支撑构件。 第二支撑构件通过第二钎焊材料附接到主体和第一支撑构件。 该结构可以包括附接到身体的第三支撑构件,该第三支撑构件与其他支撑构件中的一个成一体或分开。 用于附接支撑构件的钎焊材料可以与用于形成不同支撑构件的材料相同或不同。
