Definitions
- the invention relates to a method of bonding titanium-based metal parts, in particular of the inner shroud and of the blades of a compressor nozzle ring of an aeronautical gas turbine engine.
- EP 1 148 208 A discloses a method of bonding the blades by soldering to the inner shroud of a nozzle ring, but without indicating the constituent materials of the parts and of the solder.
- the solders generally have a sufficiently long service life in the environment mentioned above.
- the prior art does not teach what filler metals to use which are adapted to the soldering of titanium-based metals.
- the object of the invention is to fill this gap, and thus to eliminate the disadvantages of the known method of adhesion by silicone elastomers.
- the invention aims in particular at a method of the type defined in the introduction and provides that this comprises soldering under a gas pressure of less than 1.10 ⁇ 2 Pa using as a filler metal an aluminium alloy containing magnesium and virtually no silicon.
- the mechanical, physical and chemical properties of the bond obtained by the method according to the invention are an improvement on adhesive bonds. Moreover, soldering is less expensive than adhesion both in terms of its material and its implementation.
- the presence of silicon in the filler metal is disadvantageous as it reduces the temperature at which the solder can be used and its resistance to corrosion.
- the invention also relates to a gas turbine compressor nozzle ring comprising a titanium-based inner shroud, an outer shroud and a plurality of titanium-based blades distributed in the circumferential direction and extending radially from the inner shroud to the outer shroud, each blade passing through a corresponding aperture formed in the inner shroud, characterised in that the blades are fixed to the inner shroud by an aluminium-based solder containing magnesium and virtually no silicon, formed in particular by the method above.
- FIG. 1 is a partial view in axial section of a stage of an aeronautical gas turbine engine compressor nozzle ring, showing one blade connected to the inner shroud by the method according to the invention.
- FIG. 2 is a detail in section showing an aluminium alloy wire positioned with a view to soldering the blade to the inner shroud.
- FIG. 3 is a view similar to FIG. 2 showing the assembly obtained after soldering.
- shroud 1 and the blade 3 are shown diagrammatically in the form of plane plates of uniform thickness.
- the nozzle ring stage partially shown comprises, conventionally, an inner shroud 1 and an outer shroud 2 , both fixed, and a series of rectifying blades 3 extending in a generally radial direction from the inner shroud to the outer shroud.
- the blades 3 are distributed in the circumferential direction, generally in a uniform manner.
- the inner shroud 1 is pierced with apertures 4 whose shape is adapted to the profile of the blades.
- Each aperture is traversed by a blade 3 , one end region 5 of which projects in the axial direction of the engine beyond the aperture 4 and consequently beyond the inner face 6 of the shroud 1 .
- the blades 3 are fixed to the outer shroud 2 e.g. by electron-beam soldering.
- the blades 3 are fixed to the inner shroud 1 by solders 7 formed by using as a filler metal an aluminium alloy containing 0.5 to 8% magnesium by mass and virtually no silicon.
- the aluminium alloy is realised as a wire of a diameter of about 2 mm.
- the blades 3 are inserted into the apertures 4 formed in the wall of the inner shroud 1 and adapted to the transverse cross-section of the blades, in such a manner that an assembly gap or clearance 9 of a width of 0.35 mm is left around the blades between their surface and the opposite surface of the apertures 4 .
- An end region 5 of each blade projects in the axial direction of the engine beyond the inner face 6 of the shroud 1 .
- a wire 8 made of an aluminium-based alloy containing 5% magnesium and less than 0.3% silicon by mass and having a diameter of 2 mm is placed folded into a U around the region 5 , so as to come into contact with the opposite faces thereof and with the face 6 of the shroud, as is shown in FIG. 2 .
- the assembly thus obtained is placed in a vacuum furnace wherein the pressure is reduced to below 1.10 ⁇ 2 Pa. Then the following heating cycle is applied:
- the metal forming the wire 8 melts and penetrates by capillary action into the assembly gap or clearance 9 , which it fills to form upon cooling a solder 7 , which forms joining radii 10 on each side of the shroud and the blade.
- the filler metal can be realised in a form other than a wire, e.g. in the form of a strip, powder or paste, and can then be placed in the gap 9 , preferably overflowing on the inside and/or outside of the shroud 1 .
- the titanium-based metal forming the parts to be soldered may have a different composition from that of the alloy TA6V.
