Abstract
The utility model embodiment discloses a kind of surperficial figuratum carbide alloy-composite polycrystal-diamond, comprise the hard alloy layer that upper surface is provided with the special-shaped decorative pattern of several non-uniform Distribution, laminating is arranged on the compound transition zone on hard alloy layer surface, the polycrystalline diamond layer of bottom shape and hard alloy layer complementation.The utility model is by arranging rollet heterogeneous at the upper surface of hard alloy layer, there is more complicated interfacial structure, can improve further between dimond synneusis and carbide alloy in conjunction with hold, slow down, eliminate boundary layer anisotropic properties.
Description
Technical field
The utility model belongs to composite polycrystal-diamond technical field, particularly a kind of surperficial figuratum carbide alloy-composite polycrystal-diamond and preparation method thereof.
Background technology
Composite polycrystal-diamond is the composite that a kind of dimond synneusis and hard alloy substrate form, and has the advantages that hardness is high, wearability is good.
Be combined with carbide interface at glomerocryst, the Chinese patent of authorized announcement date to be the patent No. of on 06 26th, 2013 be ZL201220657434.5 has the diamond compact in straight trough indented joint face, the structure of this diamond compact bonding interface layer is for having regular texture, glomerocryst composite sheet is horizontal, longitudinal stress performance exists very big-difference, namely there is directionality, cause material anisotropy, thus cause use procedure product to destroy from most weak spot and be rapidly to other destroying and expand, reduce the performance of product.
Therefore, for the above-mentioned defect existed in currently available technology, be necessary to study in fact, to provide a kind of scheme, solve the defect existed in prior art, avoid causing dimond synneusis and carbide alloy composition surface problem loosely.
Utility model content
For solving the problem, the purpose of this utility model is to provide a kind of surperficial figuratum carbide alloy-composite polycrystal-diamond, by arranging rollet heterogeneous at the upper surface of hard alloy layer, there is more complicated interfacial structure, can improve further between dimond synneusis and carbide alloy in conjunction with hold, slow down, eliminate boundary layer anisotropic properties.
For achieving the above object, the technical solution of the utility model is:
A kind of surperficial figuratum carbide alloy-composite polycrystal-diamond, comprise the hard alloy layer that upper surface is provided with the special-shaped decorative pattern of several non-uniform Distribution, laminating is arranged on the compound transition zone on hard alloy layer surface, the polycrystalline diamond layer of bottom shape and hard alloy layer complementation.
Preferably, described special-shaped decorative pattern is that narrow and small lower end, two ends is roomy, and the degree of depth is 0.1 ~ 5mm, and decorative pattern width is 0.2 ~ 2mm.
Compared with prior art, the beneficial effects of the utility model are as follows:
(1) there is more complicated interfacial structure, can improve further between dimond synneusis and carbide alloy in conjunction with hold, slow down, eliminate boundary layer anisotropic properties;
(2) improve the shock resistance of product, improve the bending strength of product.
Accompanying drawing explanation
Fig. 1 is the cross-sectional view of the hard alloy layer of the figuratum carbide alloy-composite polycrystal-diamond in the surface of the utility model embodiment;
Fig. 2 is the cross-sectional view of the figuratum carbide alloy-composite polycrystal-diamond in the surface of the utility model embodiment.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
On the contrary, the utility model is contained any by the substituting of making on marrow of the present utility model and scope of defining of claim, amendment, equivalent method and scheme.Further, in order to make the public have a better understanding to the utility model, in hereafter details of the present utility model being described, detailedly describe some specific detail sections.Do not have the description of these detail sections can understand the utility model completely for a person skilled in the art yet.
See Fig. 1 and Fig. 2, Fig. 1 is the cross-sectional view of the hard alloy layer of the figuratum carbide alloy-composite polycrystal-diamond in the surface of the utility model embodiment; Fig. 2 is the cross-sectional view of the figuratum carbide alloy-composite polycrystal-diamond in the surface of the utility model embodiment, figuratum carbide alloy-the composite polycrystal-diamond in surface of the utility model embodiment comprises the hard alloy layer 3 that upper surface is provided with the special-shaped decorative pattern 4 of several non-uniform Distribution, laminating is arranged on the compound transition zone 2 on hard alloy layer surface, the polycrystalline diamond layer 1 of bottom shape and hard alloy layer complementation.Be in strength at embody rule, special-shaped decorative pattern is that narrow and small lower end, two ends is roomy, and the degree of depth is 0.1 ~ 5mm, and decorative pattern width is 0.2 ~ 2mm.
By the figuratum carbide alloy-composite polycrystal-diamond in surface prepared with upper type, there is more complicated interfacial structure, can improve further between dimond synneusis and carbide alloy in conjunction with hold, slow down, eliminate boundary layer anisotropic properties.
The Performance comparision of the figuratum carbide alloy in surface of the zigzag glomerocryst composite sheet manufactured under equal conditions and the utility model embodiment is in table 1.
Under table 1 equal conditions, the composite polycrystal-diamond Performance comparision of same size
| Sequence number | Glomerocryst composite sheet title | Transverse bending strength MPa | Longitudinal bending strength MPa | Remarks |
| 1 | Pattern structure | 1498 | 1496 | Isotropism |
| 2 | Broached-tooth design | 1320 | 1495 | Anisotropy |
As can be seen here, through the composite polycrystal-diamond of above-mentioned process, its anisotropy is retarded, elimination.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
