Abstract
The invention discloses a novel metal compounding process. The process comprises the following steps of: (1) performing surface roughening treatment to ensure that the surfaces of bonding layers are dissolved and roughened; (2) preparing a complex, namely adding an interlayer metal material with low melting point and high electric conductivity between substrate-layer metal and composite-layer metal so as to ensure that the interlayer metal material is permeated between the substrate-layer metal and the composite-layer metal to form metallurgical bonding; and (3) rolling the complex on a roller mill so as to closely bond the substrate-layer metal and the composite-layer metal. According to the process, an explosive cladding link is eliminated in a production environment, so that the harm of explosive cladding to the environment is reduced; the production cost is saved, and the production cycle is shortened; and moreover, the welding and rolling of all bonding surfaces are combined, so that the bonding compactness is relatively high.
Description
Technical field
The invention belongs to the preparation of metal material processing technical field, particularly metallic composite.
Background technology
What conventional metals combination process adopted mainly contains 3 kinds of techniques, compound, Explosion composite and composite technique for rolling under water.Underwater explosion compound, although can in deep water Explosion composite, can only area be applicable to little, the material that thickness is little.And the cost of raw material is higher.Large-scale production needs cannot be met.Explosion composite is on the impact of environment the most serious (shock wave, noise, dust, and the discharge of toxic gas), and also very high to the requirement of humidity in environment.The requirement that simple Rolling compund cannot meet the composite metallurgical binding gross area >=95%, single no welding zone area is less than or equal to 60c ㎡.
Existing conventional mode is the mode that Explosion composite combines with Rolling compund, thus produces qualified product.But complex process, process procedure is many, is not easy to operate the bottleneck becoming production.Batch production speed is slower.
According to retrieval, Chinese patent 99115772.9 discloses a kind of manufacture method of composite metal plate, the polishing of substrate steel billet, polishing is welded calender roll after combining base with cladding plate and becomes composite metal plate.Simultaneously 98112018.0 manufacture methods disclosing a kind of composite metal plate.Its step is 1, cleans clean by basic unit's blank 1 and cladding blank 2,2, basic unit, cladding blank are overlapped, edge, coincidence face is closed and connects, from aperture, coincidence face is evacuated to negative pressure less than 0.5 kilogram, closed pores, obtain compound list base, 3, several piece list base is overlapping, on faying surface, uniform spacer material layer, obtains composite billet, 4, by composite billet heating rolling to desired thickness, cut off edge connection portion.These metal composite methods still belong to the improvement of rolling, also exist in conjunction with the dissatisfactory problem of density.
Summary of the invention
The object of the invention is to provide a kind of Novel Titanium material combination process, to overcome the defect of existing metal composite process.
Specifically, a kind of novel metal combination process, is characterized in that implementing in accordance with the following steps:
(1) surface roughening process: by the acid of substrate layer metal and composite-layer metal surface uniform application metallic compound or catalyst or corrodible two kinds of metals in a heated state, make binder course surface dissolution coarse;
(2) compound system is standby: the interlayer metal material adding low melting point high conductivity between substrate layer metal and composite-layer metal, heating makes this interlayer metal material melt between substrate layer metal and composite-layer metal, infiltrates between substrate layer metal and composite-layer metal and forms metallurgical binding;
(3) Rolling compund body on roll mill, combines closely substrate layer metal and composite-layer metal.
The present invention omits Explosion composite link from production environment, reduces Explosion composite to the harm of environment.Save production cost, reduce the production cycle.Heating of metal is infiltrated faying face and is formed metallurgical binding face, is combined by rolling, makes bonding tightness better, improves the intensity of composition metal.
The process meanses such as the fusion of mating surface roughening, high temperature, eddy-current heating, composite effect is good.
Detailed description of the invention
A kind of novel metal combination process, is characterized in that implementing in accordance with the following steps:
(1) surface roughening process: by the acid of substrate layer metal and composite-layer metal surface uniform application metallic compound or catalyst or corrodible two kinds of metals in a heated state, make binder course surface dissolution coarse;
(2) compound system is standby: the interlayer metal material adding low melting point high conductivity between substrate layer metal and composite-layer metal, heating makes this interlayer metal material melt between substrate layer metal and composite-layer metal, infiltrates between substrate layer metal and composite-layer metal and forms metallurgical binding;
(3) Rolling compund body on roll mill, combines closely substrate layer metal and composite-layer metal.
During the roughening process of metal surface, heating-up temperature is room temperature to 800 ± 100 DEG C; And select heating-up temperature according to different materials: metallic compound is 500-800 DEG C, catalyst is 300 to 500 DEG C, acidic materials are room temperature to 300 DEG C.
Compound system for time utilize copper or aluminium or zinc or tin fusing point low, the feature that electrical conductivity is high, between substrate layer metal and composite-layer metal, add copper or aluminium or zinc or tin as interlayer metal material, and turn-on current heating incorporates after interlayer metal is melted and infiltrates in substrate layer metal and composite-layer metal.
The present invention utilizes low-melting-point metal as metal materials such as copper, aluminium, zinc, tin, the feature that electrical conductivity is high, compound with by composite in add copper product, turn-on current, adopt the heating of high frequency, intermediate frequency, low frequency, power frequency that copper is melted between, incorporate and infiltrate compound and formed metallurgical binding by composite, become composite.
Also sour corrosion means can be adopted by compound and by composite material surface roughening, heating room temperature is extremely to 800 DEG C, combine (as nitric acid, hydrochloric acid, hydrofluoric acid) in composite surface uniform application metallic compound solder flux, catalyst, a kind of acid or multiple acid to corrode corrupt split face, make binder course surface dissolution coarse, by rolling by compound with combined closely by composite.Reach the object of metallurgical binding.
The composition metal that the present invention can be prepared can be used for preparation: the composites such as titanium/steel, titanium/copper, titanium/aluminium, steel/steel, tungsten/molybdenum.
Be only several specific embodiments of the application above, but the application is not limited thereto, the changes that any person skilled in the art can think of, all should drops in the protection domain of the application.
