Abstract

An iron-copper bonded material and a preparation method thereof, belonging to the field of material technology, are formed by combining two metals, one metal is an iron alloy, and the other metal is a copper alloy; the joint of the two metals is in the form of atomic bonding; the preparation The method is: (1) process the iron alloy into an iron drum; (2) prepare the copper alloy raw material and carbonaceous material; (3) put the copper alloy raw material and carbonaceous material into the iron drum, and weld the iron cover on the iron drum , placed in a heating furnace, heated to form a melt; (4) centrifuged in a centrifuge until it is completely solidified into a copper alloy; placed in casting sand and cooled to room temperature; (5) cut along the vertical direction of the axis to obtain a double Metal disc; (6) Rolled into ring-shaped bimetallic sheet. The iron-copper bonding material in the present invention can be applied in bridging welding of dissimilar metals, high-temperature automatic protection of nuclear power plants, automatic control devices in unmanned environments, microgravity electric rotor connectors, and the like.

Description

technical field

[0001] The invention belongs to the technical field of materials, in particular to an iron-copper bonded material and a preparation method thereof. Background technique

[0002] In the research and application of traditional industries, steel and copper alloys are classified as ferrous metals and non-ferrous metals respectively due to their large differences in physical and chemical properties; In different fields, such as electronics, information, transportation, energy, metallurgy, electromechanical, etc., it plays an important role as a material. With the development of science and technology and modern industry, some emerging high-tech fields put forward new requirements for the performance of heterogeneous materials with different physical and mechanical properties at both ends: in some special environments of nuclear power plants, in both When the high temperature is close to 1,000 degrees, but exceeds 1,000 degrees, some equipment must be shut down in...
