Description
Technical field
The present invention relates to diamond fabrication technical field.
Background technology
Diamond sintering sheet includes the dimond synneusis sheet on following matrix and matrix, and matrix is Hardmetal materials, existing
In technology, dimond synneusis sheet other compositions typically no, so cause the thermal expansion system that matrix is different with dimond synneusis sheet
Number, in use, dimond synneusis sheet can burst apart on matrix, affects using effect and service life.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, it is provided that a kind of dimond synneusis sheet and matrix same expansion system
Number, reduce sintered sheets burst apart, ensure service life and using effect sintered sheets manufacture method dimond synneusis sheet and
Matrix synchronizes the manufacture method of the sintered sheets expanded.
The technical scheme is that such: dimond synneusis sheet and matrix synchronize the making side of the sintered sheets expanded
Method, it comprises the following steps: take diadust 50 57 parts according to parts by weight, cobalt powder 15 20 parts, tungsten powder 28-30 part are mixed
Conjunction stirs, and loads in metal cup, under vacuum conditions, through high pressure and 1450 DEG C of 1650 DEG C of high temperature of 5.5 7.0GPa
Being sintered on matrix, described matrix is Hardmetal materials.
Preferably, described diadust is 55 parts, cobalt powder is 16 parts, tungsten powder is 29.
The invention has the beneficial effects as follows: sintered diamond synneusis sheet and matrix that such method is produced have the most swollen
Swollen coefficient, reduces the advantage burst apart, ensure service life and using effect of synneusis sheet；Described diadust is 55 parts,
Cobalt powder is 16 parts, tungsten powder is 29 parts, also has electric conductivity good, it is possible to the advantage meeting some production requirements.
Detailed description of the invention
Below in conjunction with embodiment, the invention will be further described.

High pressure and 1450 DEG C of high temperature be sintered on matrix, described matrix is Hardmetal materials, makes the 5th sintered sheets.
5th sintered sheets is due to the dimond synneusis sheet coefficient of expansion identical with matrix, in use through the change of excess temperature
Changing, do not have the phenomenon that dimond synneusis sheet bursts apart, it is ensured that the service life of sintered sheets, this sintered sheets also has good leading
Electrically.
Embodiment 6
Taking diadust 55, cobalt powder 16, tungsten powder 29 closes and stirs, and loads in metal cup, under vacuum conditions, through 6.2GPa
High pressure and 1550 DEG C of high temperature be sintered on matrix, described matrix is Hardmetal materials, makes the 6th sintered sheets.
6th sintered sheets is due to the dimond synneusis sheet coefficient of expansion identical with matrix, in use through the change of excess temperature
