POLYCRYSTALLINE DIAMOND COMPACT
The present invention relates to a polycrystalline diamond compact. A method for manufacturing the polycrystalline diamond compact in accordance with the present invention comprises: a first assembling step for assembling a first diamond powder on an ultralight substrate; a first sintering step for forming a first polycrystalline diamond layer on the ultralight substrate by preliminarily sintering the assembled ultralight substrate and the first diamond powder on the ultralight substrate; a second assembling step for assembling a second diamond powder having particles with a diameter in the range of 0.1 to 5 μm on the first polycrystalline diamond layer; and a second sintering step for forming a second polycrystalline diamond layer on the first polycrystalline diamond layer by sintering the assembled ultralight substrate, the first polycrystalline diamond layer, and the second diamond powder on the first polycrystalline diamond layer. According to the present invention, the amount of a metal binder (catalyst) contained in a portion used for cutting rocks when performing drilling in the field, which is a surface layer of the polycrystalline diamond layer, is controlled to be minimized, thereby increasing heat resistance and enhancing abrasion resistance and impact resistance.
