Abstract

The invention discloses a composting method of a dovetail groove metal plate clearance fit interface. The compositing method is realized through the explosive cladding method, the rolling method and the like. According to the method, after a base plate with dovetail grooves and a surface plate with dovetail grooves are in interference fit, the base plate and the surface plate are composited together through combination of a metallurgical bonding mode and a squeezing meshing mode of the dovetail grooves under the actions of energy of explosives or a rolling mechanism. Physical and chemical properties of metal sheets on the two sides of a dovetail groove combination interface are not changed, and large-area metal sheet composition can be conducted; the explosive charge for a unit of compositing area is small, and atmospheric pollution, noise pollution, explosion vibration and overpressure are reduced; during explosive welding of the metal sheets with the dovetail grooves, no boundary effect exists, the compositing effect on the periphery is good, and the lower limit and the upper limit of an explosive welding window are both increased. The compositing technology of the dovetail groove metal plate clearance fit interface can be applied to the fields such as chemical reaction containers and ships so as to meet the requirement for large-area metal composite plates.

Description

technical field

[0001] The invention belongs to the field of metal plate compounding, and mainly relates to the key technology of compounding after the clearance fit between base and cladding plate with dovetail grooves. Background technique

[0002] Metal composite materials are composite materials formed by the metallurgical combination of two or more metal materials with different physical, chemical and mechanical properties by using composite technology. Metal composite materials use the "complementary effect" to make up for their respective deficiencies while maintaining the metal properties of the base metal, so as to improve the fracture toughness, impact toughness, corrosion resistance, thermal expansion, electromagnetic properties, high temperature resistance, and wear resistance of the base metal. It has been widely used in aerospace, petroleum, electric power, automobile, ship, chemical industry and many other fields.
