Description
Technical field
The invention belongs to dissimilar materials interconnection technique field, and in particular to a kind of law temperature joining side of aluminium bronze and stainless steel
Method.
Background technology
With the development of modern science and technology, change with rapid changepl. never-ending changes and improvements, single metal or conjunction also occur for material industry
Gold has been difficult to fully meet modern high technology production to the demand of material combination property, and dissimilar materials is because having different materials concurrently each
Excellent performance, it is widely used in the industrial circles such as Aero-Space, nuclear energy engineering, petrochemical industry, automobile making.
Thus, the interconnection technique about dissimilar materials turns into one of hot issue of present material connection area.
Aluminium bronze is the alloy using copper-aluminium system as base, because of its higher intensity, hardness, wearability and decay resistance, with
And relatively low material cost, have become the substitute of the alloy materials such as nickel-base alloy, stainless steel and tin bronze, be modern
Using a kind of extremely extensive Novel copper alloy in industry.Stainless steel as the greatest invention of Material Field early 20th century it
One, in addition to excellent decay resistance and heat resistance, also have higher intensity, good moulding and toughness with
And without magnetic or the advantages that weak magnetic, obtained extensively in fields such as petrochemical industry, energy project, industrial manufacture, building decorations
Application.In view of aluminium bronze and the complementarity of stainless steel in performance and economically, need two kinds in the application field of reality
Material is attached, and is prepared into a kind of aluminium bronze-rustless steel double-metal composite of excellent combination property.This aluminium bronze-
Rustless steel double-metal composite had both had the good wear-resisting and decay resistance of aluminium bronze, had stainless steel high intensity, height again
The characteristics such as hardness, it is as high intensity anti-attrition, wear-resisting and resistant material in High Voltage hydraulic system and high abrasion axle bush material
Have broad application prospects Deng field.
At present, the interconnection technique that aluminium bronze and stainless steel are most widely used is liquid-solid connection method, and it is by two kinds of materials
While heated to the fusing point temperatures above of aluminium bronze, ensures aluminium bronze fusing in high temperature environments, and stainless steel keeps solid-state, leads to
Cross liquid to spread admittedly, realize both metallurgical bindings.This method can obtain the higher double metallic composite material of bond strength, still
It is connected in high temperature environments, is easily roughened stainless crystalline grain of steel, reduces its intensity, at the same after high temperature conjunction, it is necessary to
Composite is heat-treated again, complex technical process, cost is higher.It is, thus, sought for new connection method, is dropping
On the basis of low connection temperature, ensure two kinds of materials each excellent properties and the good interface bond strength of composite.
The content of the invention
It is an object of the invention to provide a kind of law temperature joining method of aluminium bronze and stainless steel, solves prior art connection
During easy two kinds of matrix material tissues of roughening so that the problem of matrix material intensity decreases.
The technical solution adopted in the present invention is a kind of law temperature joining method of aluminium bronze and stainless steel, specifically according to
Lower step is implemented：
Step 1, surface clean is carried out to aluminium bronze coupon and stainless steel curved beam blocks；
Step 2, aluminium bronze coupon and the combination of stainless steel curved beam blocks：
The upper surface punching of stainless steel curved beam blocks after cleaning, and aluminium powder is filled in hole, then spread aluminium in upper surface
Powder, and aluminium bronze coupon is placed in the upper surface of stainless steel curved beam blocks；
Step 3, it is liquid-solid that the aluminium bronze coupon combined to step 2 and stainless steel curved beam blocks carry out microcell at low temperature
Connection, that is, obtain aluminium bronze-rustless steel double-metal composite.
Feature of the present invention also resides in,
The surface clean of aluminium bronze coupon and stainless steel curved beam blocks in step 1, it is specially：First with 600#~1000#Sand paper
The stainless steel curved beam blocks of grinding process and aluminium bronze coupon surface, are then wiped clean surface and oil contaminant with soft cloth or paper,
Progress 10~30min of supersonic oscillations in alcohol reagent is immersed in afterwards, removes remnants greasy dirt.
Stainless steel curved beam blocks upper surface is punched in step 2 a diameter of 1~3mm, depth are 0.3~1mm.
Stainless steel curved beam blocks upper surface, which is punched, in step 2 is evenly distributed on stainless steel curved beam blocks upper surface, the area in hole
Account for the 15%~25% of stainless steel upper surface area.
Stainless steel curved beam blocks upper surface is machined with the pit to cave in along edge in step 2, and in pit, aluminium bronze tries hole position
Sample block is located in pit.
It is 0.1~1mm that stainless steel curved beam blocks pit surface, which spreads aluminium powder thickness, in step 2.
Step 3 is specially：The aluminium bronze coupon combined and stainless steel curved beam blocks are placed in heating furnace, vacuumized,
Aluminium bronze coupon and stainless steel curved beam blocks are heated, when temperature reaches 700~800 DEG C, apply 3~5MPa pressure
After being incubated 20~60min, furnace cooling.
Heat temperature raising speed is 10~20 DEG C/min.
Vacuum is vacuumized in rear stove in 1~10Pa.
The invention has the advantages that the law temperature joining method of a kind of aluminium bronze of the present invention and stainless steel, first in ultrasound
Stainless steel surfaces after ripple cleaning carry out laser boring, and then plug fills out aluminium powder in the hole of stainless steel surfaces, and in stainless steel
The surface paving a thin layer aluminium powder of punching, carries out the liquid-solid connection of microcell, by micro- afterwards under the lower temperature more than aluminium powder fusing point
Both metallurgical bindings are realized in the liquid-solid diffusion in area；Meanwhile relatively low connection temperature not only avoid stainless crystalline grain of steel chi during high temperature
Modest ability is big so that the intensity of stainless steel is guaranteed, and reduces production cost, finally obtains interface cohesion with low cost
Aluminium bronze-rustless steel double-metal composite of excellent material performance near intensity stabilization, land.
