Composite plate and production method thereof

Abstract

The invention discloses a composite plate and a production method thereof, and relates to the field of new materials. The composite plate production method comprises the following steps: (I) a first metal plate and a second metal plate with a first metal material are selected, wherein the first metal plate is used for preparing a cover plate and the second metal plate is used as a substrate; (II) the cover plate is prepared, wherein at least one layer of a second material is compounded on one side of the first metal plate, such that the cover plate is obtained; and (III) the cover plate and the substrate are prepared into the composite plate through explosive welding, wherein the first metal plate and the second metal plate are contact surfaces, such that metallurgical bonding is formed between the same type of metal during explosive welding. With the method, all metal composite materials with size specifications reaching the requirements of metallurgical bonding can be produced. The production process is simple; the product reaches metallurgical bonding; and production input is low. Also, the welding surfaces of the cover plate and the substrate are of a same type of metal, such that the plates have good compatibility during the explosive welding process, and a fully combined metallurgical bonding surface can be formed. The usage amount of the surface cover plate material can be minimized, such that material cost is reduced.

Description

technical field [0001] The invention relates to the field of composite new materials, in particular to a composite board and a production method thereof. Background technique [0002] In the field of explosive welding composite metal materials, the cladding layer of the composite material is generally made of rare metal materials or other high-performance materials that are resistant to high temperature and strong acid and alkali, and the substrate is often made of common metal materials with lower prices. In the explosive welding production process, the cladding plate should not be too thin. If it is too thin, it will easily cause defects such as cladding plate breakdown, unbonded interface or edge warping. Contents of the invention [0003] The purpose of the present invention is to provide a composite plate and its production method, which fills the gap in the market for thin cladding and thick substrate composite materials, and at the same time can achieve a good explo...
