Description
Technical field
The present invention relates to aluminium jacket welding technology field, more particularly, to a kind of hot isostatic press welding included a tantalum target and aluminium jacket every
From method.
Background technology
Target needs to carry out jacket welding before Hot Isostatic Pressing Diffusion with backboard, that is, target and backboard are assembled
It is put into jacket well, then will carry out welded seal with argon arc welding.It is vacuumized after being welded, the target in jacket is made to be in
Airtight vacuum state.General common jacket material is aluminium jacket, and the welding temperature for commonly using target is 200 DEG C to 1000 DEG C.
For target with aluminium jacket with backboard under the hot isostatic pressing of certain temperature, target and backboard welding surface are diffused in one
It rises, but jacket can be also diffused with target or backboard simultaneously, leads to aluminium jacket and target (tantalum material after hot isostatic press welding
Material) it is difficult to remove.Turning is needed to remove jacket after valuable tantalum metal targets and jacket diffusion, since hot isostatic pressing is inevitable
Ground can make product generate certain deformation, this is resulted in during turning removes jacket, and also meeting is to tantalum face, to cause original
The waste of material cost.
The information for being disclosed in the background technology part is merely intended to deepen understanding of the general background technology to the present invention, and
It is not construed as recognizing or implying in any form that the information constitutes the prior art known to those skilled in the art.

The specific implementation mode of the present invention is described in detail below in conjunction with attached drawing.It should be understood that this place is retouched
The specific implementation mode stated is merely to illustrate and explain the present invention, and is not intended to restrict the invention.
Term is explained：
Diffusion Welding (Diffusion Bonding, abbreviation DB)：Weldment is fitted closely, under certain temperature and pressure
It is kept for a period of time, the atom between contact surface is made mutually to diffuse to form the welding method of connection.
Hot isostatic press (Hot Isostatic Press, abbreviation HIP)：Hot isostatic press is to utilize hot isostatic pressing technique
In high temperature and pressure sealing container, using high-pressure inert gas as medium, the sintering blank or different to powder therein or compacting
Kind metal applies each to equal isostatic pressure, the instrument and equipment of the method for formation high-compactness blank (or part).Hot isostatic press
It has become high temperature powder metallurgy, eliminate casting defect, dissimilar metal diffusion connection, Novel engineering ceramics, composite material, fire proofed wood
The advanced forming techniques such as material, high-strength graphite carbon and advanced material develop the key equipment in field.
Aluminium jacket：A kind of closed container needs jacket being evacuated to certain vacuum degree ability after welding for placing product
Hot isostatic pressing is carried out, common material is aluminium.
Fig. 1 is please referred to, below in conjunction with attached drawing to hot isostatic press welding included a tantalum target provided in an embodiment of the present invention and aluminium jacket
Partition method elaborates.
The embodiment provides a kind of hot isostatic press welding included a tantalum targets and aluminium jacket partition method, including：
Aluminium jacket 1 welding before, between tantalum target 3 and aluminium jacket 1 be equipped with one layer it is react with target or react do not fill
The separation layer 4 divided；
After Diffusion Welding, directly separation layer 4 and aluminium jacket 1 are torn from 3 surface of tantalum target.
Existing 1 welding technique of target aluminium jacket removal jacket is difficult, and turning is made to target material surface due to turning aluminium jacket 1
It is wasted at the noble metal target material cost of raw material.The present invention is exactly to solve aluminium jacket 1 and target tantalum table in diffusion welding process
The problem of face is spread together.Turning causes target source material to target tantalum surface due to avoid the turning jacket after Diffusion Welding
Cost wastes and turning aluminium jacket 1 causes processing cost to waste, and consideration pads last layer on aluminium jacket 1 and target contact surface
Isolated material.
The hot isostatic press welding included a tantalum target that embodiment using the present invention provides and aluminium jacket partition method, to avoid in heat etc.
Aluminium jacket 1 is spread together with product tantalum surface in static pressure diffusion welding process, before the welding of aluminium jacket 1, in product tantalum target 3
Surface and separation layer 4 that pad last layer is not reacted with target on 1 contact surface of aluminium jacket or that reaction is not enough, product diffusion
Directly separation layer 4+ aluminium jacket 1 can be torn from tantalum surface after welding, and separation layer 4 does not influence tantalum target 3, avoid because
Turning jacket after Diffusion Welding and turning cause that target source material cost wastes and turning aluminium jacket 1 is made to 3 surface of tantalum target
It is wasted at processing cost.
In the optional scheme of the present embodiment, further, separation layer 4 includes stainless steel substrates.
In the optional scheme of the present embodiment, further, stainless steel substrates material is 304 stainless steels.
In the optional scheme of the present embodiment, further, the thickness of stainless steel substrates is 0.1mm-0.2mm.
In at least one embodiment, the thickness of stainless steel substrates be 0.1mm-0.2mm, such as can with but be not limited only to for
0.1mm、0.11mm、0.12mm、0.13mm、0.14mm、0.15mm、0.16mm、0.17mm、0.18mm、0.19mm、0.2mm。
In the optional scheme of the present embodiment, further, stainless steel substrates are covered in tantalum target 3 and deviate from 2 side of backboard, and
The size of stainless steel substrates is identical as the size of backboard 2.
In at least one embodiment, stainless steel substrates be covered in tantalum target 3 deviate from 2 side of backboard, and positioned at tantalum target 3 with
Between aluminium jacket 1, the diameter of stainless steel substrates is identical as 2 race diameter of backboard.
The hot isostatic press welding included a tantalum target that the embodiment of the present invention provides is with aluminium jacket partition method, and 3 surface of tantalum target is not
Turning.To avoid the aluminium jacket 1 during Hot Isostatic Pressing Diffusion from being spread together with product tantalum surface, welded in aluminium jacket 1
Before connecing, product tantalum surface on 1 contact surface of aluminium jacket pad last layer react with target or react be not enough it is stainless
Steel disc.It is not enough in product with last layer is not reacted with target or reaction is padded on jacket contact surface before aluminium jacket 1 welds
Stainless steel substrates, directly stainless steel substrates+aluminium jacket 1 can be torn from tantalum surface after product diffusion welding, and stainless steel is to target
Do not influence.
The hot isostatic press welding included a tantalum target of the present invention is illustrated with aluminium jacket partition method above, still, the present invention
Be not limited to above-mentioned specific embodiment, without departing from the scope of the claims, can carry out various deformations or
Change.The invention includes various changes and modifications within the scope of the claims.
Finally it should be noted that：The above embodiments are only used to illustrate the technical solution of the present invention., rather than its limitations；To the greatest extent
Pipe is described in detail invention with reference to foregoing embodiments, it will be understood by those of ordinary skill in the art that：It is still
Either which part or all technical features can be carried out so that technical scheme described in the above embodiments is modified
Equivalent replacement；And these modifications or replacements, it does not separate the essence of the corresponding technical solution various embodiments of the present invention technical side
The range of case.
