Description
Technical field
The invention belongs to be used for the manufacture method field of the special stirring head of aluminum alloy stirring friction welding technique, and in particular to
A kind of manufacture method of aluminum alloy stirring friction welding special stirring head.
Background technology
Agitating friction welding technology (Friction Stir Welding, FSW) is a kind of known welding technique, its
The base material metal surface of weld seam both sides is extruded and high speed rotary grinding simultaneously by stirring-head, so as to produce substantial amounts of rubbing
Chafing, and then nearby weld metal reaches hot plastic state to make stirring-head, and with stirring-head rotation along weld seam advance side backward
Side is moved back to flowing, thermoplasticity metal head to be mixed is gradually cooled into weld seam after leaving.
Stirring-head as Friction stir welding core component, if dynamic load of the stirring-head under high temperature friction state
Ability, then can cause it to occur wearing and tearing faster in welding process, and cause what stirring-head was applied to weld seam mother metal
There is the change outside being expected, the mechanical property quality of final impact weld seam in welding process in pressure and frictional heat.Additionally,
The stirring-head of the dynamic load ability under high temperature friction state, its service life is shorter, it is impossible to meet needs long-time continuous
The weld seam demand of welding.
The stirring-head species of existing agitating friction welding is various, usual for aluminum alloy materials from 480-600 DEG C
At a temperature of keep hardness wearability preferable metal material when not reducing, working long hours.Tool steel, mould such as through heat treatment
Tool steel, Nickel-Based Steel, Co-Al-W alloys and the combination type stirring-head using two kinds of metal materials.
However, there is dynamic carrying capacity when working long hours under high temperature friction state in above-mentioned existing stirring-head
Difference, the relatively short problem of service life.Normally behave as, during actual welding, when stirring-head operating temperature is 550 DEG C
Under when, its Rockwell hardness reduces reaching between 45HRC-50HRC, abrasion resistance properties are reduced, mixing needle fracture failure when along axle
Shoulder root ruptures, and the service life weighed by weld seam weld length is generally below 1000 meters.Stirring-head is used as one
Planting consumable accessory improves production cost, and the unrepairable of weld defect will result directly in mother metal and scrap, and increase is manufactured into
This.Therefore, by inventing a kind of manufacture method for meeting aluminum alloy stirring friction welding special stirring head, and then stirring-head is improved
High temperature Rockwell hardness mechanical property, so as to it can improve the quality of aluminum alloy stirring friction welding and extend the use longevity of stirring-head
Life.
The content of the invention
In order to solve to be currently used for the high temperature Rockwell hardness mechanical property that the special stirring head of Friction stir welding is present
Difference, the technical problem such as service life is short, the present invention provides a kind of manufacture method of aluminum alloy stirring friction welding special stirring head.
The technical scheme that present invention solution technical problem is taken is as follows：
A kind of manufacture method of aluminum alloy stirring friction welding special stirring head, it comprises the steps：
Step one：Tungsten-carbide powder, cobalt metal powder, vanadium carbide powder, manganese Metal powder, chromium metal dust are prepared respectively
And nickel metal powder, the elemental metals powder adopts purity for 99.99%, and the granular size of its powder is 10-50 μm；
The purity of the tungsten-carbide powder or vanadium carbide powder is 99.99%, and the granular size of its powder is 20-40 μm；
Step 2：Six kinds of powdered ingredients described in step one are uniformly mixed according to following weight/mass percentage composition ratio ranges
Close：
Diamondite powder 30%-45%；
Cobalt metal powder 5%-10%；
Vanadium carbide powder 2%-5%；
Manganese Metal powder 3%-6%；
Chromium metal dust 8%-15%；

Step 3：Corresponding stirring-head mould is prepared according to the size and dimension of required stirring-head；
Step 4：In the stirring-head mould that will be put into described in step 3 after six kinds of powder mix homogeneously of step 2, and pass through
Cold isostatic press carries out preforming process, generates stirring-head preformed blank；
Step 5：Stirring-head preformed blank described in step 4 is put in vacuum sintering furnace carries out hot pressed sintering, its
Sintering process includes following sub-step：
Step 5.1：Gradually sintering furnace is warming up to into 800 degree, and is incubated 2 hours；
Step 5.2：Sintering furnace is warming up to into 1230 degree, and is incubated 2 hours；
Step 5.3：Make sintering furnace naturally cool to room temperature, make the alloy natural cooling under sintering state, generate stirring-head；
Step 6：The stirring-head produced to step 5 carries out fine-grinding and polishing process, you can complete aluminum alloy friction stir
The manufacturing process of weldering special stirring head.
The invention has the beneficial effects as follows：According to the agitating friction weldering special stirring head made by the method for the present invention, in work
When making temperature between 480 DEG C -600 DEG C, its Rockwell hardness can be reached between 55HRC-62HRC, and keeps hardness constant.Its
Service life under high temperature friction state can reach the weld seam weld length of 1500-2000 rice, therefore, can make using the method
The service life of its prepared stirring-head is greatly improved, and reduces the mixing needle fracture caused because stirring-head abrasion resistance properties are reduced
Failure or the situation that fracture occurs along shaft shoulder root occur, and thoroughly prevent the economic loss that mother metal is scrapped and caused, so that
When the novel grinding head prepared using the manner can better adapt to Friction stir welding and carry out long to very long continuous weld
