Explosive cladding method of tantalum/zirconium/titanium/steel explosive clad plate

Abstract

The invention relates to an explosive cladding method of a tantalum / zirconium / titanium / steel explosive clad plate, wherein the explosive cladding method comprises the following specific steps: a hardand flat area of soil is selected, yellow sand is paved, and leveling is carried out to serve as a foundation; a steel plate is placed on the foundation, and first supporting pieces are evenly placedon the upper surface of the steel plate; a titanium plate is placed on the first supporting pieces, and second supporting pieces are placed on the upper surface of the titanium plate; a zirconium plate is placed on the second supporting pieces, and third supporting pieces are placed on the upper surface of the zirconium plate; a tantalum plate is placed on the third supporting pieces, and the upper surface of the tantalum plate is coated with a protective layer; an explosive layer is laid on the protective layer, 2# rock emulsion explosive is laid in the center of the tantalum plate, and 1# rock emulsion explosive is laid at other positions; and a detonator is placed in the center of the 2# rock emulsion explosive, and explosive cladding operation. The fitting rate and the shearing strength of the clad plate meet the requirements of ASTM B898 'Standards for Reactive and Refractory Metal Clad Plate', the fitting rate reaches 99% or above, and the minimum shearing strength [tau]b is greater than or equal to 140 MPa.

Description

technical field [0001] The invention belongs to the field of composite plate manufacturing, and in particular relates to an explosive composite method for a tantalum / zirconium / titanium / steel explosive composite plate. Background technique [0002] Metal tantalum is a light gray metal with a slight blue color. Due to its many unique properties, it has a wide range of applications. Tantalum is very hard and its hardness can reach 6-6.5. Its melting point is as high as 2996 ° C, ranking third after tungsten and rhenium. Tantalum is malleable and can be drawn into filaments or made into thin foils. Its thermal expansion coefficient is very small, and it only expands by 6.6 parts per million per degree Celsius. In addition, its toughness is very strong, even better than copper. Tantalum also has very good chemical properties and is extremely resistant to corrosion. No matter in cold or hot conditions, it has no reaction to hydrochloric acid, concentrated nitric acid and "aqua...

Problems solved by technology

[0003] At present, most domestic tantalum / zirconium / titanium / steel explosive composite panels rely on imports from abroad, which is not conducive to the popularization and application of tantalum / zirconium / titanium / steel explosive composite panel equipment in my country, and is not conducive to the development of national industries.
