Abstract

The invention discloses a method for preparing a copper-lead alloy / steel bimetal laminated composite material, which comprises the following steps of: treating a steel plate and preheating to the temperature of between 150 and 200 DEG C in a resistance furnace; coating saturated ZnCl2 solution on the surface of the steel plate and preheating to the temperature of between 200 and 600 DEG C; smelting copper-lead alloy liquid in a medium-frequency induction furnace, namely putting charcoal and electrolytic copper into the medium-frequency induction furnace in turn, adding tin and lead after the electrolytic copper is melted, uniformly mixing and deoxidizing to obtain the copper-lead alloy liquid; and preheating a graphite mold to the temperature of 600 DEG C in a box-type resistance furnace, putting a steel substrate into the graphite mold, casting the copper-lead alloy liquid at the temperature of between 950 and 1,100 DEG C, opening the mold to take the composite material out after the temperature of the alloy is reduced to 300 DEG C, and performing air cooling. The method has the advantages of simple process and low cost; and the composite material has the advantages of high interface bonding strength, good alloy structure, and capability of meeting the operational performance of the copper-lead alloy.

Description

technical field [0001] The invention belongs to the technical field of metal composite material preparation, and relates to a preparation method of a bimetallic layered composite material, in particular to a preparation method of a copper-lead alloy / steel bimetallic layered composite material. Background technique [0002] Although each layer of bimetallic composite material still maintains its original characteristics, through composite molding, the advantages of each layer of metal can be used to supplement the deficiency of the other layer of metal, and the physical and mechanical properties of the obtained composite material are better than those of a single layer. Metal materials are far superior, expanding the range of use of the material. The literature "Casting" magazine (page 103-107 of the second issue of 2005) published "Present Situation and Research Progress of Bimetallic Composite Clad Materials". The article lists common techniques for preparing modern bimetal...
