Abstract
The utility model discloses a super-hard composite sheet, comprising at least three layers, i.e. from up to down a superfine powder layer of super-hard materials, a mixing superfine powder layer of super-hard materials and hard alloy mixing superfine powder as well as a hard alloy superfine powder layer . The structures of the utility model, that is from up to down, are a superfine powder layer of super-hard material, a mixing superfine powder layer of super-hard material and hard alloy mixing superfine powder as well as a hard alloy superfine powder layer, the well pressed composite sheets made of superfine powder to combine tightly and firmly, which can prevent the composite from breaking.
Description
Technical field
The utility model relates to a kind of Superhard composite film.
Background technology
At present, present compact structure commonly used both at home and abroad is that branch is two-layer up and down, its processing mode, be carbide alloy base and one deck superhard material micro mist be combined under HTHP with a slice moulding, but because the carbide alloy base hardness of moulding is very high, it is fashionable to carry out high voltage junction in press, occur the carbide alloy fault rupture easily, percent defective is very high so in process of production, causes high loss.
Summary of the invention
The purpose of this utility model just is to provide a kind of yield rate that can improve in the composite sheet production process, moreover can improve the Superhard composite film of the firmness of combination.
The purpose of this utility model can realize by following measure:
The utility model is to constitute by at least three layers that combine, and each layer is respectively superhard material micro mist layer, superhard material and carbide alloy admixed finepowder layer and carbide alloy micro mist layer formation from top to bottom.
Superhard composite film in the utility model is to constitute by four layers.Or, Superhard composite film is to constitute by five layers.Certainly, also can be sandwich construction.
The utility model is owing to adopt said structure, promptly each layer is respectively superhard material micro mist layer, superhard material and carbide alloy admixed finepowder layer and carbide alloy micro mist layer formation from top to bottom, the composite sheet that suppresses like this is owing to be that the raw material that adopts all is a micro mist, so in conjunction with very tight, fastness is very good, and can not cause the fracture of composite sheet.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
The utility model is done with detailed description below in conjunction with drawings and Examples:
As shown in the figure, the utility model is to constitute by at least three layers that combine, and each layer is respectively superhard material micro mist layer 1, superhard material and carbide alloy admixed finepowder layer 2 and carbide alloy micro mist layer 3 formation from top to bottom.Can be three layers, four layers, five layers or multilayer.
Operation principle of the present utility model is as follows: in the middle of press die, respectively the superhard material micro mist is inserted the carbide alloy micro mist in the mould successively, be combined into Superhard composite materials under high-temperature and high-pressure conditions.Because the superhard material micro mist contacts with the face of carbide alloy micro mist, the contact-making surface of the two can form a kind of mixed layer, i.e. superhard material and carbide alloy admixed finepowder layer.Other two-layer up and down still superhard material micro mist layer and carbide alloy micro mist layers.Ya Zhi composite sheet is because the raw material that adopts all is a micro mist like this, so combination is very tight, fastness is very good, and can not cause the fracture of composite sheet.
