Abstract: A polycrystalline diamond construction comprising a body of polycrystalline diamond material is formed of a mass of diamond grains exhibiting inter- granular bonding and defining a plurality of interstitial regions therebetween, and a non-diamond phase at least partially filling a plurality of the interstitial regions to form non-diamond phase pools, the non-diamond phase pools each having an individual cross-sectional area. The percentage of non- diamond phase in the total area of a cross-section of the body of polycrystalline diamond material and the mean of the individual cross- sectional areas of the non-diamond phase pools in the image analysed using an image analysis technique at a selected magnification is less than 0.7, or less than 0.340 microns squared, or between around 0.005 to 0.340 microns squared depending on the percentage of non-diamond phase in the total area of the cross-section of the polycrystalline diamond construction. There is also disclosed a method of making such a construction.

Abstract: A method of producing coated ultra-hard abrasive material, in particular coated diamond and CBN material. In a first step, an element capable of forming (singly or in combination) carbides, nitrides or borides to the surface(s) of the abrasive material is is applied using a hot coating process. At least one outer layer of a coating material selected from the group comprising transition metals, carbide, nitride, boride, oxide and carbonitride forming metals, metal carbides, metal nitrides, metal borides, metal oxides and metal carbonitrides, boronitrides and borocarbonitrides is applied over the inner layer by physical vapour deposition or chemical vapour deposition. Typically the inner layer elements come from groups IVa, Va, VIa, IIIb and IVb of the periodic table and include, for example, vanadium, molybdenum, tantalum, indium, zirconium, niobium, tungsten, aluminium, boron and silicon. The outer coating is preferably applied by reactive sputtering where a reactive gas is admitted to the sputtering chamber, resulting in the deposition of a compound of the reactive gas and the element being sputtered.
