Description
Technical field
The invention belongs to laminate shape metallic composite, what technical field related generally to is a kind of casting method for manufacturing layered metal composite material technology and equipment.
Background technology
Laminate shape metallic composite is to utilize various complex techniques to make two or more physics, chemistry, the metal material that mechanical property is different carries out layering combination makes it realize firm metallurgical binding and the various bilayers or the multi-gradient laminar composite that are prepared on the interface, laminate shape composite and cladded type laminar composite, although prepared each layer of composite metal still keeps primary characteristic separately, but its physics, chemistry, mechanical property is much more superior than single metal material, make the different parts of material have different performances, thereby overcome the shortcoming separately of different metal material, performance advantage separately, make material have special performances, to be suitable for and the instructions for use of satisfying various different operating modes.Reported " the compound plied timber of bimetallic prepares present situation and progress " in document " casting " magazine (second phase 103-107 page or leaf in 2005), several bimetallic plied timber technologies of preparing have been opened in the report altogether, it is roll-bonding method, the explosive welding composite algorithm, the jet deposition composite algorithm, complex techniques such as casting composite algorithm, wherein roll-bonding method is to be assembled together after the surface of metallic plate is handled by cleaning, rolling deformation by heavy reduction, what make double layer of metal treats composite surface generation plastic deformation, surface metal-layer is broken, make peace and quiet and the activation metal level expose from the metal surface of breaking, under the crunch effect, form plane metallurgical binding.After the long diffusion annealing of follow-up low temperature is handled, obtain desirable composite interface structures, form firm combination.But owing to do not spread fully and chemical reaction in the rolling recombination process, so the excessive layer structure of compound interface realizes fully that to a great extent still there is shortcoming in bond strength.This technology and be only applicable to prepare the compound of sheet metal product.
The blast composite algorithm is to drive composite plate high velocity impact substrate by the high-strength chemical energy that blast produces, the instantaneous pressure that the point of impingement produces forms skim exposing on the fresh metal surface, welding transition district with plastic deformation, fusing, diffusion and wave character, thus the metal solder that realizes strong combination is compound.Though the blast composite algorithm can be fit to prepare individual area more greatly, the production of thicker composite board or composite plate blanks, multilayer composite sheet, the composite algorithm of exploding mechanization degree is low, working condition is poor, and has certain danger, the distortion of preparation bimetallic is bigger, out-of-flatness, production cost height.
The jet deposition composite algorithm be after the high pressure draught of metal liquid by inert gas is atomized into particle jet deposition to metallic matrix, thereby formation double metallic composite material, prepared material composition uniform formation is tiny, can produce the joint product of different-thickness flexibly, but the spray atomization and deposition process is complicated, and the density of composite material is poor, the production cost height, the equipment complexity, technical difficulty is big, only use to some extent on non-ferrous metal at present, the application on ferrous metal is less.
The casting composite algorithm be with two or more metal material by the casting method it is combined into one.This technology compare with above-mentioned various combination process have the investment little, combination process is simple, production cost is low, characteristics applied widely.Introduced a kind of manufacture method of clad steel in the document, be about to by composite by surface treatment after, coat and a certain amount ofly prevent the coating of oxidation and make it dry, place it in the casting mold then, with uphill casting composite metal-liquid is poured in the type, it is coated on by composite material.Than higher, if the temperature height of casting metal is then big by the melting loss of the bottom of composite, if the excessive velocities of injecting or cross the slag inclusion that will increase slowly on the interface and can only be poured into a mould a product at every turn, production efficiency is low to the requirement of technological parameter for the method.This technology is not owing to carried out preheating by composite, thereby can only prepare compound ratio greater than the product 8.0 or more, also introduced the composite algorithm of using core in the document simultaneously, in order to production clad double metallic composite material.But because core casting composite algorithm does not still solve interface problem, when causing the composite skin to solidify, gas and impurity easily are enriched in the interface, thereby influenced product quality, and complex process, technical difficulty is big, the production cost height, narrow application range is only applicable to prepare the clad composite, and is not suitable for preparation gradient laminated-metal composite, laminate shape metallic composite.
