Description
Technical field
The invention belongs to metallic composite fields, and in particular to a kind of composite metal structures with reinforcing function and its
Forming method and application.
Background technology
Metal material is most-often used one of material in national product life, has high intensity, high rigidity, appearance tactile impression
The advantages that good, has very extensive application foundation in fields such as building, military project, aerospace, 3C electronics, daily necessities.Amorphous
Alloy material is a kind of novel metal material of high speed development in recent years, has high specific strength, specific modulus, higher hard
Degree, wear-resisting and corrosion resistance, are applied in fields such as aerospace, motor racing product, consumer electronics and cause to get over
Carry out more concerns.But due to the unique microcosmos structure characteristic of non-crystaline amorphous metal, non-crystaline amorphous metal itself is made not have plastic deformation
Or plastic deformation ability is relatively low, after arrival elastic limit and the characteristic of failure fracture also limits its application range.For
The above situation has a large amount of research work to improve the moulding index of non-crystaline amorphous metal, such as generates interior raw reinforcing by constituent adjustment
The modes such as phase, surface stress processing, face coat, but cannot achieve the effect that ideal.
As application number 200880105518.4 is entitled《For by the method in glass insert one earth subsidence to metal edge frame
And the electronic equipment produced》Patent in the scheme that proposes：Transparent component is positioned in mold, then by the amorphous of liquid
State alloy is injected into above-mentioned mold, then makes amorphous alloy hardening to make amorphous alloy and transparent component form one
Component.The preparation method of raw hardening constituent is same or similar with above-mentioned technical proposal in non-crystaline amorphous metal in the prior art, is profit
Integral component is formed with the heterogeneous component different from non-crystaline amorphous metal material and non-crystaline amorphous metal, using being placed in amorphous in a mold in advance
Either heterogeneous component is then injected into liquid or softening another composition of state to alloy, is finally made using techniques such as die casting, hot pressing
Integral component is formed, and heterogeneous component constitutes the interior raw hardening constituent in amorphous alloy structure.
Above-mentioned technical proposal in many documents and patent although disclosed, and carried out to it there are many researcher
The improvement more refined, such as increases the mode of connection structure, but is not used widely but in practical manufacturing technology,
The reason is that the interior raw hardening constituent in above-mentioned technology is distributed since each position cooling rate of product is variant to exist
The uncontrollable situation of even property, the integration product produced is during by die casting or thermal stress, interior raw reinforcing
It is mutually difficult to uniformly meet with stresses, it is inconsistent so as to cause degree of strain, the phenomenon that easily producing fracture.It is difficult to gram for above-mentioned
The shortcomings that taking, it was also proposed that the technical solution of some relevant surface stresses processing and face coat, is in non-crystaline amorphous metal
Surface forms the structure of resistance to deformation, thinks to offset thermal stress whereby, reduces the influence that pressure internally gives birth to hardening constituent, but in product
Actual crack pattern under, surface stress processing and the technique effect that can generate of face coat are very limited, and surface is answered
Power processing and face coat structure are new technical process, and the difficulty of whole technique processing is greatly improved after increasing, from
And the cost of the product prepared is directly improved, more limit the application of this technology.

The advantages of alloy material, is in forming process and the rheology ratio after the fusion temperature of base metal structure material and fusing
More similar, die-casting process easy to use is molded, difficulty is lower for industrialization manufacture, homogeneity of technical process more
To be apparent, yield is high.
The hardness at reinforcement position is then made to be obviously improved using ceramic material, simultaneously because ceramic surface has hole knot
Structure can combine more closely with base metal material, while ceramic material appearance is more special, using outsourcing, penetrates, portion
When the modes such as connection being divided to carry out reinforcement, the part of exposing can compare special appearance processing, keep overall appearance special, increase
The surcharge of product.Ceramic material oxide ceramics preferably identical with base metal structure material master alloying ingredient, carbonization
Object ceramics or carbide ceramics, can be combined more closely with base metal structure, such as zirconium-base amorphous alloy
Base metal material, using ZrC, ZrN, ZrO2Ceramics are used as supporting material；For the base metal material of al based amorphous alloy,
Using Al2O3Ceramics are used as supporting material.
Cermet material equally can also reach superior effect as reinforced structure part material, it is preferred to use carbide
One kind in based ceramic metal, nitride based ceramic metal, boride-base cerment, silicide based ceramic metal, hardness height,
It is tightly combined with base metal structure, and with metal and ceramic two kinds of surface structures, is conducive to the design of product overall appearance.
As the preferred of reinforced structure part material, elasticity more preferably fibrous material or high temperature resistant plastic cement material also can be used
Material, particularly preferred fibrous material, including carbon fiber, graphite fibre, silicon carbide fibre, polycrystalline mullite fibre, alumina fibre,
One kind in Zirconium oxide fibre, alumina silicate fibre.Fibrous material, if polycrystalline mullite fibre tolerable temperature is up to up to 1300 DEG C
More than, molding is simple, of low cost, it is often more important that the use of fibrous material can effectively reduce the weight of bulk metal component
Amount, achievees the purpose that lightweight product.
Finally, it should be noted that above example be only to illustrate the embodiment of the present invention technical solution rather than to its into
Row limitation, although the embodiment of the present invention is described in detail with reference to preferred embodiment, those skilled in the art
It should be understood that the technical solution of the embodiment of the present invention can be still modified or replaced equivalently, and these are changed or wait
The range of modified technical solution disengaging technical solution of the embodiment of the present invention cannot also be made with replacement.
