Description
Technical field
The invention belongs to composite superhard material manufacturing fields, and in particular to a kind of synthesis technology of composite superhard material.
Background technique
In the composite superhard material manufacturing in China, usually with hard alloy and superhard material (diamond or cube
Boron nitride etc.) on cubic hydraulic press, a kind of completely new composite superhard material product is synthesized by high temperature and pressure.It is all at present
It is all almost the same for manufacturing the production technology of composite superhard material product, it may be assumed that by assembled composite superhard material pyrophillite
Synthesis of cubic body is placed among six top hammers of cubic hydraulic press, after press system pressure is risen to 50~90MPa, just
Power on, directly to composite superhard material pyrophillite cube heat temperature raising；When synthesis pressure reaches rated pressure (90~
100MPa) heat temperature raising still continues for some time, and when heat temperature raising finishes, composite sheet superhard material cube is taken out after release
Body breaks pyrophillite, and taking-up has synthesized the composite superhard material product finished, and the synthesis technology of a round trip terminates.This mesh
The synthesis technology in forward position has a fewer defects, most important one be in hard alloy metallic atom in the effect of high temperature and pressure
Under, the largely dialysis into superhard material；And product type seeps although completely the same to superhard material in each round trip technique
The amount of analysis be it is inconsistent, this also causes the tenor in superhard material to be 9~20% to differ, and the metal in superhard material
The inconsistent single product quality that will cause in whole batch products of content is uneven, unstable.
In addition, by inspection and practical application, the thermal stability for the composite superhard material product that prior art is prepared
It is low, wear resistance ratio decline.Moreover, the yield rate of products obtained therefrom is low, and generally below 85%.
Summary of the invention
The purpose of the present invention is to provide hard alloy element dialysis during a kind of reduction synthesis composite superhard material, drops
Tenor in low superhard material, improves the yield rate and thermal stability of composite superhard material, and improves the compound super of wear resistance ratio
The synthesis technology of hard material.
Technical program of the present invention lies in providing a kind of synthesis technology of composite superhard material, the synthesis technology include with
Lower step:
1) hard alloy of assembling and superhard material are placed in pyrophillite body, are added in cubic hydraulic press, are forced into
8-10MPa, and it is warming up to 700 DEG C~800 DEG C；
2) it is further forced into 90~100MPa, is warming up to 1400 DEG C~1700 DEG C.
The present inventor has found in production practice, metal contained in the superhard material of composite superhard material product
It is a key index for influencing product quality.How much metalliferous institute is in superhard material in composite superhard material product, directly
Determine two physical properties of product most critical, a thermal stability, two are wear resistance ratios.Thermal stability refers to product through height
Temperature welding after physical properties parameter with before high-temperature soldering compared with the case where, reduction the smaller proof thermal stability of amplitude
It is good, (traditional handicraft reduces amplitude up to 10%~40%).And tenor is directly proportional to wear resistance ratio decline, i.e., tenor is got over
Height, generated wear resistance ratio drop-out value are bigger.Even if the superhard material of composite superhard material product is added without metal in proportion,
But in high temperature and pressure synthesis, metal in hard alloy is to superhard material dialysis, and metal increases in superhard material, causes hot steady
Qualitative variation, wear resistance ratio reduce.
In this regard, inventor has carried out a large amount of trial and test, it is desirable to be able to improve to above situation.And then it proposes
Technical solution of the present invention.
Specifically, in the synthesis process, being first forced into 5-10MPa, then make the heating hammer flat side of a hammer and leading in pyrophillite body
Electric steel ring is in close contact, and power transmission heat temperature raising, when being warming up to 700 DEG C~800 DEG C, diamond or boron nitride are at 700 DEG C~800 DEG C
In the temperature of (unprotect gas), the compound working lining of diamond or boron nitride approaches and reaches theoretical density, and surface can be light
It is micro- nitridation and metallic atom can not jump the traces power at these temperatures.It is further forced into 90~100MPa, is warming up to 1400
At DEG C -1700 DEG C, the combination between finish button and key, make the powder body being made of numerous fine particle become one it is firm
It is whole.The speed for reducing the metal dialysis in superhard material achievees the purpose that reduce tenor in superhard material.
The present invention further comprises following preferred technical solution:
Preferred scheme further comprises step 3) on the basis of step 1), step 2): by cubic hydraulic press two
The pressure increase 10%~40% of a heating hammer flat side of a hammer, remaining four surface pressure are constant.
It is pressurizeed by third time, the pressure that two heating hammer flat side of a hammers are born is continued to increase, is higher than the non-heated hammer flat side of a hammer
Pressure 3%~40%, and in vertical state by the hard alloy of control assembling and superhard material and two heating hammers, Ke Yiyou
The retardance metallic atom movement velocity of effect, to achieve the purpose that further decrease the tenor in superhard material, to improve
The thermal stability and wear resistance ratio of super-hard compound material provide effective guarantee.
Preferred scheme, on the basis of step 2), further by the pressure of the cubic hydraulic press two heating hammer flat side of a hammers
Increase by 3%~40%, remaining four surface pressure is constant.
Preferred scheme, in step 3), by the pressure increase 10%~20% of the cubic hydraulic press two heating hammer flat side of a hammers.
Preferred scheme in step 1), keeps 30s-50s after being warming up to 700 DEG C~800 DEG C.
Preferred scheme in step 2), keeps 100s-1000s after being warming up to 1400 DEG C~1700 DEG C.
Preferred scheme in step 3), keeps 1-5min after pressurization.
Preferred scheme in step 1), after being first forced into 5-10MPa, then heats up.
Preferred scheme in step 2), after being first forced into 90~100MPa, then heats up.
Preferred scheme, in step 3), two heating hammers and the hard alloy assembled are vertical with superhard material.
Preferred scheme, the superhard material are diamond and/or cubic boron nitride.
Beneficial effects of the present invention:
