Abstract
The invention discloses a production technology for quickly synthesizing polycrystalline diamond. Graphite is transformed into polycrystalline diamond under the action of a catalyst through different ultrahigh temperatures and high pressures in a short time. The polycrystalline diamond produced by the production technology disclosed by the invention has small surface internal stress and uniform distribution of internal stress, and the service life of the polycrystalline diamond is greatly prolonged.
Description
Technical field
The present invention relates to the synthetic field of superhard material, relate in particular to the adamantine production technology of a kind of quick synthesised polycrystalline.
Background technology
Along with appearance and the development of superhard material, opened up wide market prospects for the production of diamond.Diamond has been walked close to people's life more and more, so people are also more and more deep with research to the production of diamond, purposes and the efficient of diamond is more and more improved.
Generally, diamond is under the high pressure high temperature condition, is under the participation with long time and catalyst metal, the high grade monocrystalline diamond that is transformed by graphite.This traditional for a long time synthetic production, cost compare is high, and the low and product quality of production efficiency can not get stable control.
Summary of the invention
In order to overcome defects, the invention provides the adamantine production technology of a kind of quick synthesised polycrystalline.
To achieve these goals, technical scheme of the present invention is: the adamantine production technology of a kind of quick synthesised polycrystalline may further comprise the steps:
1), synthetic piece that catalyst and raw material will be housed assembles, baking is 12-14 hour under 200 ℃ of-230 ℃ of conditions;
2), will synthesize piece and put into press, starting pressure is raised to 60MPa;
3), started afterwards heating in 30 seconds, heating power is 15KW, heating current is 4000A;
4), the heating 29 seconds after, rising pressure is to 80MPa;
5), continue heating after 6 seconds, the heating power bust is to 12KW, stopped heating behind the heating current 3150A;
6), continue pressurize, dwell pressure is 80MPa;
7), 6-10 stops pressurization, synthesised polycrystalline diamond after second.
The invention has the beneficial effects as follows: the diamond Surfaces of Polycrystalline Diamond internal stress that the present invention produces is little, and internal stress is evenly distributed, and has greatly improved the service life of polycrystalline diamond.
Description of drawings
Fig. 1 is process chart of the present invention.
The specific embodiment
The present invention is described further below in conjunction with specific embodiment.
As shown in Figure 1, may further comprise the steps:
1), synthetic piece that catalyst and raw material will be housed assembles, baking is 12-14 hour under 200 ℃ of-230 ℃ of conditions;
2), will synthesize piece and put into press, starting pressure is raised to 60MPa;
3), started afterwards heating in 30 seconds, heating power is 15KW, heating current is 4000A;
4), the heating 29 seconds after, rising pressure is to 80MPa;
5), continue heating after 6 seconds, the heating power bust is to 12KW, stopped heating behind the heating current 3150A;
6), continue pressurize, dwell pressure is 80MPa;
7), 6-10 stop after second the pressurization, synthesised polycrystalline diamond, prioritization scheme are 10 seconds.
Technical scheme of the present invention is not limited to the restriction of above-mentioned specific embodiment, and the technology distortion that every technical scheme according to the present invention is made all falls within protection scope of the present invention.
