Abstract
The utility model discloses a high-efficient wear-resistant shock-proof polycrystalline diamond compact, wherein a shock-proof alloy layer is arranged on the surface of a polycrystalline diamond layer. A thin layer of shock-proof materials is applied to the surface of the polycrystalline diamond layer, and therefore shock degree of the polycrystalline diamond layer is reduced, shock-proof performance of the polycrystalline diamond compact is intensified, and self-sharpening performance of the polycrystalline diamond is improved. Meanwhile, shock-proof layers with different surface shapes can effectively improve the chip removal environment of the polycrystalline diamond compact, and improve shock-proof performance and cutting efficiency of the polycrystalline diamond compact. The high-efficient wear-resistant shock-proof polycrystalline diamond compact can be used for a polycrystalline diamond compact (PDC) drill, and therefore the PDC drill can keep quick in drilling all the time, and wearing quality of the polycrystalline diamond compact is improved. Meanwhile, the shock-proof layer and the different surface shapes of the shock-proof layer can improve shock-proof performance, partial hydraulics states, cutting conditions and the chip removal environment of PDC drill teeth, and improve a mechanical drilling speed and service life.
Description
Technical field
The utility model belongs to the super-hard compound material technical field; Relate to soft creeping into to hard rock; Relate in particular to a kind of PDC composite sheet that is applicable to that various polycrystalline diamonds (PDC) drill bit is used; Also relate to the PDC composite sheet that the borings cutter head is used, particularly a kind of high-efficiency abrasion-proof shock resistance composite polycrystal-diamond.
Background technology
At present; The composite polycrystal-diamond goods are a lot of both at home and abroad, and the glomerocryst laminar surface has different shape, mainly is in order to improve a certain performance of composite sheet; Or the stock-removing efficiency of increase composite sheet; Or the abrasion resistance of raising composite sheet, or the shock resistance of enhancing composite sheet, but improve a certain performance another performance is descended.Like application number is 201110001815.8 utility model patents and ZL200620016041.0 utility model patent; Mainly be in order to improve the stock-removing efficiency of composite sheet, but therefore type composite sheet air spots, shock resistance descends to some extent; When cutting fragmentation and complicated rock, can shorten application life; The patent No. is 200820053178.2 utility model patent for another example, mainly is in order to increase the shock resistance of composite sheet, but because of its surface becomes sphere or cambered surface, and when cutting complete homogeneous rock, efficiency of breaking rock can descend to some extent.Yet for the composite sheet that is used for cutting, no matter run into which type of rock, it is optimal result that performances such as stock-removing efficiency, abrasion resistance and impact resistance improve simultaneously.
The utility model content
The purpose of the utility model is in order to overcome the deficiency of above-mentioned prior art, and a kind of high-efficiency abrasion-proof shock resistance composite polycrystal-diamond is provided.
The utility model is to be provided with one deck impact resistance alloy-layer at the polycrystalline diamond laminar surface.
The anti-ballistic materials of the material of described impact resistance alloy-layer for protecting polycrystalline diamond layer to avoid impacting, this anti-ballistic materials can be a carbide alloy.
The section of described polycrystalline diamond layer and anti-ballistic materials is an Any shape.
Described shock resistance alloy-layer is to be combined in the polycrystalline diamond laminar surface through high temperature and high pressure method.
Increase the skim anti-ballistic materials at the polycrystalline diamond laminar surface; Can alleviate the impact resistance of composite polycrystal-diamond; Increase the self-sharpening of polycrystalline diamond; The anti-impacting layer of different surfaces shape can effectively improve composite polycrystal-diamond chip removal environment, improves the impact resistance and the stock-removing efficiency of composite polycrystal-diamond.
The utility model is applied to polycrystalline diamond (PDC) drill bit, the PDC drill bit is remained creep into soon and improve the wearing and tearing quality of composite sheet.Anti-impacting layer and different surfaces shape thereof can be improved impact resistance, partial water mechanics state, machining condition and the chip removal environment of PDC bit teeth, can improve rate of penetration and application life.
The beneficial effect of the utility model: the high-efficiency abrasion-proof shock resistance composite polycrystal-diamond of the utility model, have long, characteristics such as drilling speed is high, energy consumption is low, antiseized ability is strong of life-span, greatly practice thrift cost, improve the quality of products.
