Abstract
The utility model discloses the two-sided composite sheet of a kind of diamond, comprises matrix and diamond layer, and the upper and lower two ends of matrix are provided with circular platform type projection, and the cross sectional shape of circular platform type projection is the heart of at least three most advanced and sophisticated concurrents, and center superposition that is most advanced and sophisticated and matrix.Circular platform type projection is set at matrix upper and lower two ends, does not affect the flowing of diamond dust, and projection contacts with diamond dust, increases contact area, adds the bond strength of the two, be conducive to the diffusion of cobalt; 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 the two-sided composite sheet of a kind of diamond.
Background technology
Diamond compact refers to and add a small amount of metal or non-metallic binder in diamond abrasive grain, through the composite that high temperature, high-pressure synthesis obtain, because it has such as: excellent properties such as hardness are high, thermal conductivity good, shock resistance is high, and be widely used in the fields such as oil field mining, infrastructure construction, building maintenance, machining, geological prospecting, along with the development of science and technology, also become the indispensable critical materials of high-tech area such as microelectronics, communication, space flight.At present, diamond compact generally adopts diadust as primary raw material, and add a small amount of catalyst CATALYST Co, Ni etc., combine with carbide alloy, sintering forms.Its products characteristics is: structure is very fine and close, hardness is higher, causes that shock resistance in its use procedure is poor, to cut sharpness poor, makes to bore in drilling process that tooth abnormal destruction phenomenon is more and drilling depth is too slow.
Utility model content
The purpose of this utility model is to provide and a kind ofly increases the contact area of diamond layer and matrix and the two-sided composite sheet of diamond of bond strength.
The utility model realizes above-mentioned purpose by the following technical solutions: the two-sided composite sheet of a kind of diamond, comprise matrix and diamond layer, the upper and lower two ends of matrix are provided with circular platform type projection, the cross sectional shape of circular platform type projection is the heart of at least three most advanced and sophisticated concurrents, and center superposition that is most advanced and sophisticated and matrix, the distance between the heart tip of described projection and heart-shaped solstics is less than the radius of matrix.
Described heart-shaped convex surfaces is provided with heart-shaped groove.
The degree of depth of heart-shaped groove is 1/5th of height of projection.
Relative to prior art, the utility model arranges circular platform type projection at the upper and lower two ends of matrix, the cross sectional shape of circular platform type projection is the heart of at least three most advanced and sophisticated concurrents, and center superposition that is most advanced and sophisticated and matrix, do not affect the flowing of diamond dust, and projection contacts with diamond dust, increases contact area, add the bond strength of the two, be conducive to the diffusion of cobalt; 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.
