Abstract
The present invention discloses an aluminum base middle-layer alloy for liquid phase diffusion welding. The weight percentage of all elements is: 60% to 95% of aluminum, 0.5% to 10% of silicon, 0.5% to 35% of copper, 0.5% to 10% of magnesium, 0.001% to 1% of gallium, and 0.001% to 0.1% of rare earth. The present invention can be applied to welding various products made of aluminum and aluminum alloys.
Description
Technical field
The present invention relates to a kind of aluminium base intermediate layer alloy that is used for liquid-phase diffusion welding, be specially adapted to the aluminium base intermediate layer alloy of aluminium and the diffusion welding (DW) of aluminium alloy liquid phase.
Background technology
Aluminium and aluminium alloy are because characteristics such as little, the good corrosion resistance of density, heat-conductivity conducting be good and in Aeronautics and Astronautics, military affairs and civil area extensive use.Because there is the very fine and close oxide-film of one deck on the surface of aluminium and alloy thereof, the character of this layer oxide-film is highly stable, can fully resist the erosion of atmosphere, and it can generate new film again at any time when old film is broken, so aluminium and the very difficult welding of alloy thereof.
Someone adopts Vacuum Soldering Technology to carry out the welding of aluminium and alloy thereof, adds Mg in the scolder as the essential element of removing oxide-film, and is aided with vacuum condition and removes oxide-film again.But Vacuum Soldering Technology is very sensitive to the slight change of parameter, is difficult to guarantee that solder is even, and scolder and mother metal effect are incomplete, and weld strength is low, and qualification rate is low; Adopt vacuum equipment in addition, the cost height, the cycle is long, efficient is low.
Summary of the invention
The object of the present invention is to provide a kind of aluminium base intermediate layer alloy, can realize aluminium and alloy thereof are connect at the liquid-phase diffusion welding under the atmospheric conditions.
The technical solution adopted for the present invention to solve the technical problems is: the aluminium base intermediate layer of liquid-phase diffusion welding alloy, the content of its each element (percentage by weight) is: aluminium 60%～95%, silicon 0.5～10%, copper 0.5～35%, magnesium 0.5～10%, gallium 0.001%～1%, rare earth 0.001%～0.1%.
Rare earth element is at least a in lanthanum, cerium, the neodymium.
The fusing point in aluminium base intermediate layer is 480 ℃～580 ℃.
Aluminium base intermediate layer of the present invention alloy has identical matrix element aluminium with welding base metal aluminium and alloy thereof, has guaranteed that intermediate layer and mother metal have good wetting property, has reduced the discontinuous of composition and tissue, has strengthened the adhesion in mother metal and intermediate layer.Silicon, copper and aluminium can low temperature eutectic, guarantee the toughness and the bending strength of welding point.Magnesium can react with oxide-film, reaches the purpose of direct removal oxide-film.Gallium is a low melting point element, has very high flowability in aluminium and alloy thereof, and can be diffused rapidly to the crystal boundary of aluminium, broken oxide-film.It is to purify crystal boundary that rare earth element mainly acts on, and suppresses the generation of second phase.
Its preparation method is that each component percentage by weight is in accordance with regulations made foundry alloy; foundry alloy is packed in the quartz crucible; eddy-current heating remelting under the protection of high-purity argon gas; after reaching suitable temperature; argon gas with certain pressure rotates fused solution alloy spray to cast on the red copper roller in the high speed of any surface finish, and chilling just can obtain the aluminium-based amorphous alloy metallic foil that thickness is 0.02～0.10mm.
Compared with the prior art, the liquid-phase diffusion welding that aluminium base intermediate layer of the present invention alloy is finished aluminium and alloy thereof connects, and welding cost is low, and the time is short, and the efficient height can be widely used in the welding of various aluminium and Al-alloy products.
The specific embodiment
Provide specific embodiments of the invention below.
The aluminium base intermediate layer of a kind of liquid-phase diffusion welding alloy, its each weight percentages of components be, silicon 8%, and copper 2.5%, magnesium 2%, gallium 0.03%, cerium 0.02%, surplus is Al.
Aluminium base intermediate layer alloy is prepared into the film that thickness is 0.05mm.
The liquid-phase diffusion welding that the aluminium base intermediate layer of this composition is used for φ 60 * 8 alusil alloy pipes (LF2) connects, and the result is: break during stretching at mother metal, tensile strength is σ
b=215MPa reaches the tensile strength (σ of mother metal
b〉=170MPa); Crooked 90 ° break.
