Abstract
The invention discloses a super-hard composite material with rigid alloy sandwich, while the rigid alloy sandwich is arranged along the axial center of the super-hard composite material, wherein the outer layer of the sandwich is one super-hard layer composed of artificial diamond or cubic boron nitride, and conjugation agent. The conjugation agent is at least one of aluminium nitride, titanium nitride, molybdenum nitride, nitride magnesium, nitride zirconium, nitride chromium, nitride tungsten, aluminum oxide, cobalt, molybdenum, titanium, iron, aluminum, nickel, copper, tungsten, and chromium. The surface of the sandwich is concave-convex one, while the sandwich and the super-hard layer are combined via concave-convex contact surfaces. The invention uses the concave-convex engaged sandwich structure, to improve bending strength and impact flexibility of the super-hard composite material, reduce the consumption of super-hard material powder, and reduce production cost, thereby expanding the application range of the super-hard composite material.
Description
Technical field
The present invention relates to a kind of superhard composite body, especially relate to a kind of superhard composite body with carbide alloy sandwich with carbide alloy sandwich.
Background technology
Diamond, cubic boron nitride are two kinds of the highest materials of hardness in the world, and wherein diamond hardness in all known substances is the highest, and cubic boron nitride hardness is only second to diamond, but its hear resistance and higher to the chemical stability of ferrous metal.Have good serviceability by superhard material powder and a small amount of bond through the superhard glomerocryst material that the HTHP sintering forms, be widely used in the machining tool field.But the superhard glomerocryst toughness of material of producing is not enough at present, is prone to the phenomenon of bursting apart in the use.And need to consume a large amount of superhard material powder, production cost is higher, makes to use to be restricted.
Summary of the invention
That purpose of the present invention just is is not high at superhard glomerocryst toughness of material, easily burst apart, and the problem that production cost is high, by introducing the carbide alloy sandwich and adopting special-shaped fit structure to improve the bending strength and the impact flexibility of glomerocryst material, can reduce simultaneously the consumption of superhard material powder, reduce production costs.Thereby provide a kind of superhard composite body with carbide alloy sandwich.
Purpose of the present invention can realize by following measure:
The present invention includes superhard composite body, along the superhard composite body axis part is the cemented carbide body sandwich, the skin of cemented carbide body sandwich is a ultra hard material layer, ultra hard material layer is made up of diamond or cubic boron nitride and bond, bond is selected from aluminium nitride, titanium nitride, molybdenum nitride, magnesium nitride, zirconium nitride, chromium nitride, tungsten nitride, alundum (Al, cobalt, molybdenum, titanium, iron, aluminium, nickel, copper, tungsten, in the chromium any one or a few, cemented carbide body sandwich surface is a male and female face, combines by the convex-concave contact-making surface between described cemented carbide body sandwich and the ultra hard material layer.
The male and fomale(M﹠F) on the cemented carbide body sandwich surface among the present invention is concave and convex plane or concave-convex curved surface.Cemented carbide body sandwich surface has shape concurrently for boss or concave station or concavo-convex.Pass through convex-concave contact-making surface sinter bonded together between cemented carbide body sandwich and the ultra hard material layer.
The present invention has improved the bending strength and the impact flexibility of superhard composite body owing to adopt the special-shaped sandwich structure that cooperates of above-mentioned convex-concave, reduces superhard material powder consumption simultaneously, reduces production costs, thereby the scope of application of superhard composite body is further enlarged.
