Abstract
The utility model discloses a kind of diamond compact, comprise matrix and diamond layer, uniform setting at least three boss on described matrix, boss cross sectional shape is heart-shaped, and the angle α between adjacent heart-shaped boss both sides is 1 ° ~ 5 °.The faying face of composite polycrystal-diamond is provided with and is uniformly distributed multiple heart-shaped projection, the angle α between adjacent heart-shaped boss both sides is 1 ° ~ 5 °, increases the bonded area of matrix and diamond layer, adds the bond strength of the two; After diamond layer is combined with matrix, the heart projection on matrix is deep in diamond layer and forms carbide alloy skeleton, is conducive to the toughness and the impact strength that improve diamond layer, also reduces the use amount of diamond dust simultaneously, reduce manufacturing cost; After diamond layer is combined with matrix, the Thickness Ratio centre position of diamond layer edge and effective operating position is thick, thus can increase the wear resistance of composite sheet.
Description
Technical field
The utility model relates to super-hard compound material field, particularly a kind of diamond compact.
Background technology
Composite polycrystal-diamond is the composite of a kind of diamond layer and hard alloy substrate composition, hardness is high, wearability is good feature that it has.Existing composite polycrystal-diamond is mainly divided into composite polycrystal-diamond (PCD) and polycrystalline diamond composite sheet to bore tooth (PDC), wherein, composite polycrystal-diamond (PCD) is used to the composite superhard material making diamond cutter, because its high hardness and wearability, alternative traditional high-speed steel and hard alloy cutter become carpenter and field of machining first-selection; Polycrystalline diamond composite sheet bores the crucial composite superhard material that tooth (PDC) is oil, natural gas and geological drilling, is the main working parts on diamond bit and material, and its performance quality, directly determines the efficiency of oil-gas geology probing.
In the design of existing composite polycrystal-diamond hard alloy substrate, generally have following several: one is exactly planar structure, its diamond layer of the composite polycrystal-diamond produced with this matrix and hard alloy layer faying face less, hold is therebetween little, and bond strength is little; One is horizontal parallel groove type structure, although this design increases diamond layer and hard alloy layer bonded area, the center thickness simultaneously indirectly causing again diamond layer thickens, and has certain waste to material.
Utility model content
The purpose of this utility model is to provide a kind of diamond compact, increases the bonded area with diamond layer, increases the bond strength of matrix and diamond layer, is beneficial to flowing and the compacting of diamond dust, improves impact resistance and the abrasion resistance of product.
The utility model adopts technical scheme to realize above-mentioned purpose:
A kind of diamond compact, comprises matrix and diamond layer, and uniform setting at least three boss on described matrix, boss cross sectional shape is heart-shaped, and the angle α between adjacent heart-shaped boss both sides is 1 ° ~ 5 °.
The most advanced and sophisticated concurrent of heart-shaped boss, with the center superposition of matrix bodies.
Heart-shaped boss upper surface is provided with heart-shaped groove, and groove depth is the 1/5-1/4 of heart-shaped boss height.
The matrix of composite polycrystal-diamond and the faying face of diamond layer are provided with and are uniformly distributed multiple heart-shaped projection, angle α between adjacent heart-shaped boss both sides is 1 ° ~ 5 °, increase matrix and the bonded area of diamond layer, add the bond strength of the two; After diamond layer is combined with matrix, the heart projection on matrix is deep in diamond layer and forms carbide alloy skeleton, is conducive to the toughness and the impact strength that improve diamond layer, also reduces the use amount of diamond dust simultaneously, reduce manufacturing cost; Heart is raised with and is beneficial to brill and upwards spreads, and cobalt can be diffused in the middle of diamond dust fully under high-temperature liquid-phase state, and catalytic action is better, and the cobalt penetrated in diadust is more, more easily allows between diadust and grows into together, enhance product performance; After diamond layer is combined with matrix, the Thickness Ratio centre position of diamond layer edge and effective operating position is thick, thus can increase the wear resistance of composite sheet.

Detailed description of the invention
As shown in Figure 1, a kind of diamond compact, comprises matrix 1 and diamond layer, described matrix 1 is arranged uniformly three boss 2, boss cross sectional shape is heart-shaped, and the angle α between adjacent heart-shaped boss both sides is 5 °, the most advanced and sophisticated concurrent of heart-shaped boss 2, with the center superposition of matrix 1; Heart-shaped boss upper surface is provided with heart-shaped groove 3, and groove depth is the 1/5-1/4 of heart-shaped boss height, and heart-shaped boss upper surface is provided with heart-shaped groove, can increase diamond layer and protruding contact area and bond strength.
As shown in Figure 2, arrange four boss above matrix bodies uniformly, the angle α between adjacent heart-shaped boss both sides is 3 °; As shown in Figure 3, arrange five boss above matrix bodies uniformly, the angle α between adjacent heart-shaped boss both sides is 1 °.
