(a) providing a substrate (10) which has a surface (14) to which the layer of bonded ultra-hard abrasive particles is to be bonded;
(b) providing a slurry of the components, in particulate form, necessary to make the layer of bonded ultra-hard abrasive particles in a liquid medium adapted to flow and to set to a green state under predetermined conditions;
(c) applying a layer (18) of the slurry to the surface (14) of the substrate (10);
(d) applying the predetermined conditions during step (c) or immediately thereafter to cause the liquid medium to set to a green state;
(e) contacting the green state layer (18) with a complemental surface (22) provided on a pressure pad (20);
(f) removing substantially all the liquid medium from the green state layer (18);
(g) placing the substrate/pressure pad combination in the reaction zone of a high temperature/high pressure apparatus; and

摘要： A diamond or cubic boron nitride compact is produced by subjecting a mass of coated diamond or cubic boron nitride particles to conditions of temperature and pressure at which the abrasive particle is crystallographically stable. This causes the coatings to solid sinter and bond the abrasive particles. The coating for the abrasive particles is a refractory oxide, nitride or carbide.

摘要： A method is provided for making a product which comprises two layers of different materials bonded to each other. The product will typically be a composite abrasive compact. The method includes the steps of providing a mould (10) having an internal base surface (16) profiled to a desired shape, making a first slurry of a particulate material in a liquid medium which is capable of setting at least to a green state, introducing the slurry (20) into the mould (10), causing the medium to set to produce at least a green state mass (20), removing the green state mass (20) from the base (16), that green state mass (20) having a surface complementary to the profiled internal base surface (16) of the mould (10), depositing, on the profiled complementary surface of the green state mass, a layer of a second slurry containing a different particulate material in a liquid medium which is capable of setting at least to a second green state, and causing the medium of that second slurry to set to produce at least a second green state mass (26) which is bonded to the first green state mass (20).

摘要： A method of producing an abrasive product comprises the steps of providing a mixture of diamond and discrete carbide particles, the diamond particles being smaller than the carbide particles and present in the mixture in an amount of more than 50 percent by volume, and subjecting the mixture to diamond synthesis conditions in the presence of a binder metal such as cobalt, nickel or iron. The abrasive product thus produced has a substantial amount of direct diamond-to-diamond bonding and many of the characteristics of a diamond compact, but improved impact resistance due to the presence of the carbide particles. The abrasive product has particular application in the machining of wood products such as natural wood, chipboard, fibreboard and hardboard.
摘要翻译：一种生产研磨产品的方法包括以下步骤：提供金刚石和离散碳化物颗粒的混合物，所述金刚石颗粒小于碳化物颗粒，并且以大于50体积％的量存在于混合物中，并使混合物在金属如钴，镍或铁之类的金属存在下进行金刚石合成条件。由此产生的磨料产品具有大量的直接金刚石 - 金刚石结合和金刚石压块的许多特征，但由于碳化物颗粒的存在而提高了耐冲击性。研磨产品特别适用于天然木材，刨花板，纤维板和硬质合金等木制品的加工。
