Abstract
The radial compressor rotor consists of an alloy containing at least aluminum and copper, which can be hardened by heat treatment. This is the basic material. An additional material to the basic material. This consists of an alloy containing aluminum and resistant to high temperatures. This combination forms a gradient material.
Description
Technical field
The present invention relates to a kind of by a kind of Centrufugal compressor impeller and manufacture method of making by the stock of heat hardenable (the w rmeaush rtbar) alloy composition that contains aluminium and copper at least thereof.
Background technique
A kind of disclosed Centrufugal compressor impeller that is used for exhaust-gas turbocharger is made by aluminium-cooper-maganesium alloy.In order to carry out hermo-hardening, this alloy is carried out T6 heat treatment.This heat treatment regulation, to alloy at first carry out for the time general three hours, temperature probably is 500 ℃ heating, then to this alloy apace quenching to room temperature.Then this material is remained on a thermal aging temperature that is approximately 180 ℃ to 200 ℃, for the time eight hours.Then can be with this material cooled to room temperature.
A Centrufugal compressor impeller of so making only has limited high-temperature capability.When the outlet temperature of air reaches at short notice or surpassed this thermal aging temperature, in the outer rim of this impeller, the overageing of material can appear in the compressed air outlet zone promptly so.This overageing causes the decline of intensity, so for example can produce by coming off of impeller part and damage.
Summary of the invention
Task of the present invention is to provide the Centrufugal compressor impeller of an aforesaid kind, and this Centrufugal compressor impeller can bear the higher heat load in gas outlet to be compressed zone.
According to the present invention, this task solves in the following way, and promptly the perimeter of this impeller is made up of a kind of additional materials using stock to constitute under a kind of situation of functionally gradient material (FGM), and this additional materials is made of a kind of alloy resistant to elevated temperatures, that contain aluminium.So just can make a kind of Centrufugal compressor impeller with sufficient intensity with resistant to elevated temperatures perimeter.
According to the first string of the present invention, the additional materials of perimeter is by a kind of alloy composition that contains aluminium and carbon at least.According to another aspect of the present invention, the additional materials of perimeter is by a kind of alloy composition that contains aluminium and iron at least.
For making the Centrufugal compressor impeller of an aforesaid kind, use stock and blank that constitutes by a kind of functionally gradient material (FGM) of additional materials manufacturing of powder metallurgy state by a kind of drawing method of thermal insulation static state.For identical purpose also can be made a blank that is made of a kind of functionally gradient material (FGM) by the stock of injection compression fusing and the additional materials of fusing.
Description of drawings
From additional dependent claims and by accompanying drawing to obtaining other features of the present invention the description of two schemes of the present invention.In the accompanying drawings, what accompanying drawing 1-5 showed is first embodiment's manufacture process, and what accompanying drawing 6 and 7 was showed is second embodiment's manufacture process.
Embodiment
In first embodiment, make a box 1 of making by thin aluminum shell, the shape of this box corresponding to consider after method step in the profile of the Centrufugal compressor impeller to be made under the material contracts situation of generation.In this box, pack in order to constitute pulverous stock 2 of Centrufugal compressor impeller major component.This stock is made of a kind of alloy that has the constituent element of aluminium and copper at least.Other alloy compositions also can comprise wherein as magnesium.This stock is milled into or is atomized into fine powder before the box 1 of packing into.
As shown in Figure 2, then after be used to constitute the perimeter of blade rear, packing in box 1 is similarly pulverous additional materials 3.This additional materials 3 has alloy compositions aluminium and carbon, and a spot of in case of necessity other components.
Behind the additional materials 3 of packing into, box 1 then is pumped into vacuum by 4 sealings of a lid.Then as shown in Figure 3, this box 1 is carried out the static compression process of thermal insulation of high pressure, high temperature.
As shown in Figure 4, by the blank 5 of an integral type of the static compression process formation of this thermal insulation, this blank has a transition region 6 between stock 2 and annex material 3, have the component of two kinds of materials in this transition region.
After the forging molding of following, may carry out aforesaid T6 heat treatment in case of necessity to the stock 2 of this blank 5.
As shown in Figure 5, in order to constitute rotor body 7 and blade 8, then blank 5 is carried out cutting.It can be seen that the perimeter of blade 8 is made up of resistant to elevated temperatures additional materials 3.By constituting a kind of functionally gradient material (FGM), although improve the mechanical strength that the heat resistance of the perimeter of blade 8 still can guarantee impeller with material 2 and 3.
In a second embodiment, reuse aluminium copper, and can add a spot of other components, as magnesium as stock.Use a kind of heat-resisting, quick-setting alloy as additional materials, in this alloy, also can add a spot of other additional alloy compositions with aluminium and iron component.
These two kinds of materials are melted respectively, and are directed in the container 12 of protected gas purge by pipeline 10,11 separated from one another, and this container has the coolship 13 of a rotation in its underpart.Be respectively equipped with a nozzle 14,15 in the end of pipeline 10,11, nozzle sprays the material of liquid state with the small shape that drips.Wherein, the orientation of nozzle 14 makes this nozzle that this stock 16 is ejected on the coolship 13 as central core.In contrast, the orientation of nozzle 15 makes this nozzle will drip additional materials 17 that shape sprays in the rotation process of coolship 13 equably from the outer jet to the stock on 16.Container 12 is filled with shielding gas in this process always.As shown in Figure 6, by spraying compression, just formed a cylindrical body that is made of functionally gradient material (FGM) on coolship 13 like this, this cylindrical body has stock 16 in inside, externally have additional materials 17, and has the transition region that is positioned between the two.Wherein, for this purpose nozzle 14,15 can be settled on this cylindrical longitudinal axis movably.
As shown in Figure 7, then in order to constitute blank 18, cut apart the cylindrical body of forming by functionally gradient material (FGM) by horizontal cutting.
These blanks 18 are also the same as die forging with first embodiment then, carry out T6 heat treatment, then are cut processing.
