Problems solved by technology

There are very few composite materials with a total thickness greater than 6mm and a cladding of less than 2mm on the market, mainly because it is difficult to produce or the cost is too high by conventional methods
The rolling composite method can produce metal composite materials with a cladding layer of less than 2mm, but generally the total thickness does not exceed 3mm. If it is necessary to produce a composite plate with a thickness of 6-8mm, the initial equipment investment is very large; the explosive composite method can produce composite materials with a total thickness greater than 6mm. , but the minimum coating thickness can only reach 2mm

Abstract

The invention discloses a composite plate and a production method thereof, and relates to the field of novel materials. With the method provided by the invention, a composite plate with a coating layer thickness lower than 2mm can be prepared, such that a metallurgically bonded ultra-thin-coat metal composite plate can be obtained. The production method comprises the steps of coating material preparation, composite material preparation and heat treatment. According to the ultra-thin-coat metal composite material, the coating material is prepared through the metal composition methods of rolling composition, explosive cladding, spray coating, electroplating, and the like. The composition of the coating and a substrate is realized with an explosion or rolling method. The thickness of the coating of the ultra-thin metal composite material is lower than 2mm, and the total material thickness of the composite material can be set to any thickness. Therefore, a vacancy of the composite plate with the coating thickness within this range is filled.

Description

technical field [0001] The invention relates to a production method of a thin-clad metal composite board. The final cladding thickness of the thin metal composite material of the invention is less than 2mm, and the total thickness of the material is not limited, which fills the blank of the cladding thickness cladding board in this range. Background technique [0002] At present, most of the metal composite materials that have achieved metallurgical bonding in China are produced by rolling cladding and explosive cladding. The thickness of the cladding of the rolled cladding is about 1mm, and the total thickness is about 3mm; the thickness of the cladding of the explosive cladding is greater than 2mm. There are very few composite materials with a total thickness of more than 6mm and a cladding of less than 2mm on the market, mainly because it is difficult to produce or the cost is too high by conventional methods. The rolling composite method can produce metal composite mater...
