Summary of the invention
The object of the invention is for the above-mentioned problems in the prior art, propose a kind of mechanical property, electric property is better, the TV close junctor that work-ing life is of a specified duration.
Object of the present invention realizes by following technical proposal: a kind of TV close junctor, comprise connector body, this connector body is made up of 3 D weaving carbon fiber/copper alloy composite material, and 3 D weaving carbon fiber/copper alloy composite material comprises volume percent content and is respectively the 3 D weaving carbon fiber of 5-10% and the copper alloy of 90-95%.
Because carbon fiber has higher intensity, toughness, shock resistance, resistance to fatigue and good focus performance, tensile strength and modulus in tension are considerably beyond copper alloy, so carbon fiber add the conductivity and heat conductivility that have not only increased substantially matrix material, also substantially increase the mechanical property of matrix material, especially improve the ability that matrix material bears External Force Acting, increase substantially the tensile strength of matrix material, flexural strength etc.In addition, carbon fiber makes matrix material with copper alloy after making prefabricated component by the method for 3 D weaving again, matrix material is made to have excellent holistic resistant behavior, use junctor conductivity, mechanical property and excellent in mechanical performance that this matrix material is made, not easily deform during use damage.Meanwhile, the high thermal conductivity of carbon fiber and low heat expansion property can make junctor coating metal heating degree reduce, thus reduce the thermal fatigue proneness of junctor, extend the work-ing life of junctor.And carbon fiber density is little, alleviate the weight of junctor, it is convenient, convenient to use, and the resistance to chemical corrosion of carbon fiber enhances the wearing quality of matrix material.
If 3 D weaving carbon fiber in the composite content is very few, do not have good enhancement, if but content is too much, degraded appearance, and surface floating fiber is comparatively serious, and over-all properties is difficult to effectively improve.Therefore the present invention is based on copper alloy, the 3 D weaving carbon fiber adding 5-10% forms the good 3 D weaving carbon fiber/copper alloy composite material of over-all properties, and be used for making junctor of the present invention, thus junctor of the present invention is made to have good over-all properties.
In above-mentioned a kind of TV close junctor, copper alloy is made up of following composition (by percentage to the quality): Ni:2.0-3.5%, Si:0.5-1%, Zn:2.0-2.5%, P:0.01-0.05%, Fe:0.01-0.05%, Zr:0.05-0.3%, rare earth element: 0.1-0.5%, Pb < 0.02%, Bi < 0.002%, surplus is Cu and inevitable impurity element.
The moiety of copper alloy of the present invention and mass percent compatibility thereof rationally, ensure that the intensity of copper alloy.Wherein, Zn solid solubility in copper alloy is comparatively large, and the Zn element of high-content of the present invention can play solution strengthening effect to copper alloy.Ni element can put forward heavy alloyed intensity, toughness and stress corrosion dehiscence resistant ability.Si element also can put forward the performances such as heavy alloyed intensity, hardness, and a small amount of Pb element existed in Si element and alloy can play synergy, can also reduce the rubbing factor of alloy.
Zr element also containing trace in copper alloy of the present invention, Zr element can form precipitated phase that is tiny, Dispersed precipitate in the alloy, thus microhardness and the recrystallization temperature of alloy can be significantly improved, enable alloy meet the performance requriements of high strength, high conductivity.
The trace P element also contained in copper alloy of the present invention and Fe element can form Fe
2p, also can improve intensity and the stress relaxation resistance of alloy while not falling low-alloyed electroconductibility.
In addition, the rare earth element added in copper alloy of the present invention can make copper alloy cast structure dendrite grid attenuate little, the obvious refinement of grain structure after distortion annealing.And adding rare earth element can also purify alloy, eliminates the deleterious effect of its impurity.In the present invention, rare earth element is preferred is further (0.5-2) by Ce and Y in mass ratio: 1 forms.Because rare earth element ce can also generate CuCeP intermetallic compound with Cu and P element, this intermetallic compound is that point-like Dispersed precipitate is at crystal boundary or intracrystalline, can refining alloy tissue, the dislocation desity in alloy substrate can also be significantly improved, thus effectively improve the hardness of Sn-P-Cu alloy, enhance the wear resistance of alloy.And rare earth element y also can the crystal grain of remarkable refining alloy, puies forward heavy alloyed intensity and hardness; And after interpolation rare earth element y, the bonding force of copper alloy matrix strengthens, and corrosion resistance nature is improved.
Therefore, with the junctor that 3 D weaving carbon fiber/copper alloy composite material of the present invention is prepared into, not only there is the excellent performance such as intensity, hardness, stress relaxation-resistant, and there is excellent electric conductivity.Compared with the junctor be prepared into Sn-P-Cu alloy, the performance such as intensity, hardness of the junctor that the performance such as intensity, hardness of the junctor that copper alloy of the present invention is prepared into is prepared into apparently higher than Sn-P-Cu alloy, especially, the electric conductivity of junctor that copper alloy of the present invention is prepared into is more than 3 times of the electric conductivity of the junctor that Sn-P-Cu alloy is prepared into.
In above-mentioned a kind of TV close junctor, 3 D weaving carbon fiber is that carbon fiber forms to shuffling by three-dimensional five, and braid angle is 20-35 degree.Carbon fiber has excellent stitchability, and braid angle is the good stability of the prefabricated component of 20-35 degree, and the composites performance made is more excellent.
In above-mentioned a kind of TV close junctor, the surface of carbon fiber is formed with SiC coating, and the thickness of SiC coating is 0.6-1.2 μm.Because the modulus of carbon fiber and copper alloy differs greatly, in the preparation process of matrix material, the wettability of liquid copper alloy to carbon fiber is very poor, and the interface of carbon fiber and copper alloy is the physical bond based on mechanical bond, and interface is both without spreading also without chemical reaction.This interface cohesion is more weak, and its lateral shear intensity is less, limits the raising of the strength of materials.And SiC is when the molten metal contacts be melt into copper alloy, reducing metal in carbon fiber surface and copper alloy reacts and generates Si, in Si and copper alloy, the wetting property of Cu is better than the wetting property of Cu and carbon fiber greatly, therefore the present invention has one deck SiC coating with the wetting property of both increases in the surface-coated of carbon fiber, improves the infiltration of liquid metal to carbon fiber and the stability at interface.
In above-mentioned a kind of TV close junctor, SiC coating adopts physical sputtering method to be formed on carbon fiber, when wishing that coatingsurface is coarse, when increasing with the wettability of matrix and bonding force, can select d.c. sputtering.Physical sputtering ratio juris is the Ar with certain energy in vacuum chamber
+particle bombardment cathode targets-SiC plate, pounds SiC molecule from SiC plate, sputter with high-octane SiC molecule deposition on carbon fiber, form SiC coating.The SiC coating generally obtained by chemical vapour deposition can affect intensity and the tensile property of fiber, but carbon fiber of the present invention is by forming the SiC coating that thickness is 0.6-1.2 μm after physical sputtering method, low-fiber intensity and tensile property not only do not fall, the tensile property of carbon fiber can be improved on the contrary, its reason is that SiC coating improves the state of carbon fiber surface, compensate for the surface imperfection caused in preparation process, thus improve the intensity of composite filament, avoid the deficiency of many chemical vapour depositions: as the chemical erosion of ion pair carbon fiber various in coating procedure, the deposition damage of a small amount of uncombined carbon or the silicon packed structures of SiC deposition, and application temperature is high, cause aging and high unrelieved stress of carbon fiber etc. in a word, physical sputtering method coating SiC in carbon fiber surface be a kind of low cost, effective coating method.
In above-mentioned a kind of TV close junctor, 3 D weaving carbon fiber/copper alloy composite material is obtained by following preparation method: carbon fiber surface being formed with SiC coating makes 3 D weaving carbon fiber by three-dimensional five to shuffling, pour into after 3 D weaving carbon fiber being fixed on mould by the metal liquid of smelting copper alloy, obtain 3 D weaving carbon fiber/copper alloy composite material work in-process, by first for work in-process pressurize, then take out and heat-treat to obtain 3 D weaving carbon fiber/copper alloy composite material.Due to the flexibility of 3 D weaving carbon fiber, be difficult to form firm support, therefore when pouring into molten metal, need first 3 D weaving carbon fiber to be fixed in a mold, and then pouring into molten metal, the speed poured into should not be delayed not anxious, and molten metal is fully filled in carbon fiber skeleton.
In above-mentioned a kind of TV close junctor, dwell pressure is 0.12-0.16MPa, and the dwell time is 15-25min.Due to the increase of dwell pressure, pumping rate is also increase, and the increase of pumping rate, is conducive to the timely feeding at composite material solidification position, improves the quality of matrix material further.
In above-mentioned a kind of TV close junctor, thermal treatment, for being first incubated 2-3h at 520-560 DEG C, is then incubated 1-2h at 600-630 DEG C.The present invention, by the thermal treatment of two gradients, is first promoted the performance of matrix material, is then consolidated by the thermal treatment of a rear gradient again, make performance more stable by the thermal treatment of the first gradient.
Namely 3 D weaving carbon fiber/copper alloy composite material of the present invention can be made into TV close junctor of the present invention by common moulding process, as shaping in cold forgeability, casting etc.
