Abstract
The utility model discloses a kind of Superhard composite materials, comprise matrix and diamond layer, matrix is provided with projection, and the center of described projection is a round platform, is annulus outside round platform, circle ring center and round platform central coaxial, and described round platform is cylindricality round platform or the frustum of a cone.The projection that round platform forms with annulus contacts with diamond dust, increases contact area, adds the bond strength of the two, is conducive to the diffusion of cobalt; Projection on matrix is deep in diamond layer, be conducive to the toughness and the impact strength that improve diamond layer, spacing d between annulus and round platform is greater than the thickness of annulus, be less than the radius of round platform, be groove between annulus and round platform, increase contact area, add the bond strength of the two, also reduce the consumption of diamond dust simultaneously, reduce manufacturing cost; Frustum cone height is greater than annulus height, and after diamond layer is combined with matrix, the Thickness Ratio centre position of diamond layer edge and effective operating position is thick, can increase composite sheet wear resistance.
Description
Technical field
The utility model relates to super-hard compound material field, particularly a kind of Superhard composite materials.
Background technology
Diamond compact refers to and add a small amount of metal or non-metallic binder in diamond abrasive grain, through the composite material 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 Superhard composite materials of bond strength.
The utility model realizes above-mentioned purpose by the following technical solutions: a kind of Superhard composite materials, comprise matrix and diamond layer, matrix is provided with projection, the center of described projection is a round platform, it is annulus outside round platform, circle ring center and round platform central coaxial, described round platform is cylindricality round platform or the frustum of a cone, and frustum cone height is greater than annulus height.
Spacing d between annulus and round platform is greater than the thickness of annulus.
Spacing d between annulus and round platform is less than the radius of round platform.
Relative to prior art, the utility model is provided with projection on matrix, protruding center is round platform, be annulus outside round platform, circle ring center and round platform central coaxial, described round platform is cylindricality round platform or the frustum of a cone, the projection that round platform forms with annulus contacts with diamond dust, increase contact area, add the bond strength of the two, be conducive to the diffusion of cobalt in matrix; 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.
Accompanying drawing explanation
Fig. 1 is the structural representation of matrix of the present utility model.
Fig. 2 is the utility model structural representation.
Detailed description of the invention
As shown in Figure 1 and Figure 2, a kind of Superhard composite materials, comprise matrix 1 and diamond layer 4, matrix 1 is provided with projection, and the center of described projection is a round platform 2, it is annulus 3 outside round platform 2, annulus 3 center and round platform 2 central coaxial, described round platform is cylindricality round platform or the frustum of a cone, and frustum cone height is greater than annulus height, spacing d between annulus and round platform is greater than the thickness of annulus, and the spacing d between annulus and round platform is less than the radius of round platform.
The projection that round platform forms with annulus contacts with diamond dust, increases contact area, adds the bond strength of the two, is conducive to the diffusion of cobalt; Projection on matrix is deep in diamond layer and forms carbide alloy skeleton, be conducive to the toughness and the impact strength that improve diamond layer, spacing d between annulus and round platform is greater than the thickness of annulus, be less than the radius of round platform, be groove between annulus and round platform, increase contact area, add the bond strength of the two, also reduce the use amount of diamond dust simultaneously, reduce manufacturing cost; Frustum cone height is greater than annulus height, and 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 composite sheet wear resistance.
