Embodiment Construction

[0012] A novel metal composite process is characterized in that it is implemented according to the following steps:

[0013] (1) Surface roughening treatment: evenly apply metal compounds or catalysts or acids that can corrode the two metals on the surface of the metal of the substrate layer and the metal of the composite layer under heating, so that the surface of the bonding layer is dissolved and rough;

[0014] (2) Composite preparation: Add a low-melting-point high-conductivity interlayer metal material between the substrate layer metal and the composite layer metal, heat the interlayer metal material to melt between the substrate layer metal and the composite layer metal, and penetrate into the substrate layer. A metallurgical bond is formed between the layer metal and the composite layer metal;

[0015] (3) The composite body is rolled on a rolling mill to tightly combine the metal of the base layer and the metal of the composite layer.

[0016] When roughening the met...

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 [0001] The invention belongs to the technical field of metal material processing, in particular to the preparation of metal composite materials. Background technique [0002] There are mainly three kinds of processes used in the traditional metal cladding process, underwater cladding, explosive cladding and rolling cladding. Although underwater explosive compounding can be explosively compounded in deep water, it can only be applied to materials with small area and small thickness. And the raw material cost is higher. It cannot meet the needs of large-scale production. Explosive recombination has the most serious impact on the environment (shock waves, noise, dust, and toxic gas emissions), and it also has high requirements for humidity in the environment. Simple rolling compounding cannot meet the requirements that the total metallurgical bonded area of ​​the composite material is ≥95%, and the single unbonded area area is less than or equal to 60c㎡.
