Abstract

The invention relates to the technical field of diamond compacts, in particular to a non-uniformly distributed preformed diamond compact and a preparation method thereof. The non-uniformly distributedpreformed diamond compact comprises a hard alloy matrix and a polycrystalline diamond layer, wherein at least two grooves distributed around the axis are formed in the edge of the upper end surface of the hard alloy matrix; the polycrystalline diamond layer comprises a first block corresponding to the upper end surface of the hard alloy matrix up and down and second blocks in one-to-one correspondence to the grooves up and down; and the lower end surface of the polycrystalline diamond layer is connected with a connecting surface in a shape matching manner. The preparation method comprises thesteps of processing a hard alloy meter, manufacturing the polycrystalline diamond layer, manufacturing a combination body, carrying out machining and carrying out cobalt removal treatment. The product provided by the invention has relatively high wear resistance and impact resistance at the same time.

Description

technical field [0001] The invention relates to the technical field of diamond composite sheets, in particular to a non-uniform preformed diamond composite sheet and a preparation method thereof. Background technique [0002] Due to its excellent performance, diamond composite sheets are used in various exploration and drilling fields, especially in strata with high hardness, complex geology, and many gravels. Compared with carbide drill bits and diamond-impregnated drill bits, etc. Obvious use advantages and performance characteristics of traditional products. Especially in use, due to both impact resistance and wear resistance, the service life can reach 3 to 10 times that of traditional products, and it has received more and more attention and application. [0003] At present, the cutting part of the diamond composite sheet is made of the same material, that is, it is pressed from the same proportion of powder. The components of the existing powder include fine-grained d...
