Definitions
- the present invention relates to a method for manufacturing by diffusion welding of a single-piece part for a turbomachine such as a turbojet engine or an airplane turboprop, this part being for example a power transmission shaft between the main shaft of a turbojet and gearbox drive machines or accessory equipment of the engine (commonly called AGB shaft in the field, AGB being the acronym for Accessory Gear Box).
- a turbomachine such as a turbojet engine or an airplane turboprop
- this part being for example a power transmission shaft between the main shaft of a turbojet and gearbox drive machines or accessory equipment of the engine (commonly called AGB shaft in the field, AGB being the acronym for Accessory Gear Box).
- the AGB shaft is relatively thin and long, with a length of the order of one meter for large diameter motors, and is generally made in two parts arranged end to end for reasons of mechanical strength and vibration. The adjacent ends of these two parts are guided and centered in rotation by an intermediate bearing ensuring the passage of the natural modes of vibratory frequencies.
- This method consists in forming a blank of the shaft around a rotating cylindrical mandrel by winding on the mandrel at least one wire coming from a coil or a reel, so as to form several coaxial annular layers and superimposed wire son surrounding the mandrel and which are each formed of several contiguous turns, and then subjecting the blank to a treatment of hot isostatic pressing (CIC) diffusion welding (CIC, Hot Isostatic Pressing - HIP) in a appropriate tools.
- CIC hot isostatic pressing
- HIP Hot Isostatic Pressing - HIP
- the invention aims in particular to provide a simple, effective and economical solution to this problem.
- each layer of metal son of the blank is formed of independent rings which are engaged on the mandrel and stacked next to each other.
- the metal wires form independent rings that do not come directly from a reel or a reel and are not wound on the mandrel, which makes it possible to produce circular or non-circular section pieces.
- the stacking of the rings on the mandrel can be done at room temperature.
- the circular section pieces are made from circular rings which are engaged on a cylindrical mandrel.
- the non-circular section pieces (and for example polygonal: triangular, rectangular, square, etc.) are made from rings of corresponding non-circular shape which are engaged on a mandrel of complementary shape (non-cylindrical).
- the rings are engaged on the mandrel being positioned at one end of the mandrel, coaxially with it, and then being moved in translation on the mandrel, parallel to its longitudinal axis.
- the rings of the same layer are stacked on top of each other.
- the rings of the same layer are arranged horizontally next to each other.
- the compression can be done in isothermal press or in an autoclave bag, according to the number of pieces to produce.
- the rings are preformed before engagement on the mandrel to adopt the aforementioned circular or non-circular form.
- the preforming of the rings allows them to take any shape corresponding to the section of the piece to be made.
- the rings of an inner layer have a polygonal shape and the rings of an outer layer have the same polygonal shape with a transverse dimension greater than that rings of the inner layer.
- the preforming of the rings can be done manually (for small diameter wire) or by means of appropriate tools.
- the diameter of the wire of the rings is for example between 1 and 6mm approximately.
- the mandrel has a radius which is preferably greater than the diameter of the wire of the rings.
- the rings can be closed or not split.
- the inner and outer diameters of these rings are fixed and each ring of an outer layer extends around a ring of an inner layer and is aligned transversely with that ring of the inner layer.
- the outer diameter of a ring of an inner layer is equal to the inner diameter of a ring of the outer layer surrounding the inner layer.
- the closed rings can be obtained directly by their manufacturing process. Alternatively, they can be obtained by conformation of a wire metal whose free ends are close together and fixed to one another, for example by welding.
- the stack of these rings is square type. Indeed, a half cross-sectional view of these rings comprises four circles whose centers are located at the four corners of a square. In a particular embodiment of the invention, the expansion of this stack is of the order of 21.5%.
- the rings are of the open or split type at a point in their circumference.
- these rings are deformable by spacing or approximation of their free ends.
- the outer diameter of a ring of an inner layer is then greater than the inner diameter of a ring of the outer layer surrounding the inner layer.
- the stack of these rings (of the same diameter) is of the equilateral triangle type, a half cross-sectional view of these rings comprising three circles whose centers are located at the corners of an equilateral triangle.
- the expansion of this stack is of the order of 9.31%.
- each split ring engaged on the mandrel is preferably angularly offset from those of the adjacent rings around the longitudinal axis of the mandrel. This makes it possible to distribute these openings around the longitudinal axis of the mandrel, over the entire axial dimension of the mandrel and to avoid creating zones in the blank where the amount of metal supplied by the wires would be insufficient and would generate voids in the piece to realize.
- the part to be produced is for example a shaft or a disk or bladed ring monoblock (DAM or ANAM) turbomachine.
- At least one annular layer of metal-coated ceramic fibers formed for example of a fabric or a sheet of fibers, is disposed between two layers of metal son.
- Each fiber comprises a core of ceramic material (such as silicon carbide Sic) covered with a coating (by EGV or other) of metal (Ti, Al, B, etc.), this metal being preferably the same as that of the aforementioned rings.
- the part thus comprises, after diffusion welding, a homogeneous metal matrix which provides a binder function for the part and protection of the fibers which take up the forces to which the part is subjected.
- This solution makes it possible to increase the stiffness of the part without increasing its density. It also makes it possible to increase the Young's modulus ratio on the density of the part and to raise the natural modes of vibratory frequencies. In the case of an AGB shaft, it makes it possible to eliminate the aforementioned intermediate bearing which is no longer necessary.
- Other materials such as SiC fabrics, Ti, Al, or TiAI strips or any material having properties for superplastic forming and diffusion bonding may be wound or stacked around the mandrel.

- the mandrel 12 has a cylindrical shape in the example shown but could have another shape in section, for example triangular, square, rectangular, or polygonal, as will be described in more detail in the following.
- This mandrel is arranged vertically or horizontally and can be fixed.
- the rings 10 are engaged on the mandrel 12 being positioned at one end of the mandrel, coaxially with it, and moved in translation on the mandrel, parallel to the axis A.
- An annular flange 14 is preferably mounted on the mandrel at one end thereof and forms bearing means of the first ring of each annular layer extending around the mandrel.
- the rings 10 are stacked at a distance L which is determined according to the length of the part to be manufactured.
- the number of rings per layer is a function of the diameter of the wire which is for example between 1 and 6 mm.
- the rings can be made of TiA6V or ⁇ 6242 type titanium alloy providing thermomechanical and light weight resistance.
- the rings 10 are shaped so as to take a shape corresponding to the shape of the part to be manufactured, which may be circular, square, rectangular, triangular, and so on.

- Each ring of an inner layer is surrounded by a ring of an outer layer, these two rings being located in the same plane transverse to the axis A.
- FIG. 6 represents the transverse half-sections of four adjacent rings distributed on two layers, an inner layer formed of two rings and an outer layer formed of two rings surrounding the two rings of the inner layer.
- the stack is of the square type because the centers of the half sections (in the form of a circle) of the wires are located at the four corners of a square. In a particular embodiment of the invention, the expansion of this stack is of the order of 21.5%.
- the diameters of the split rings 10 can be modified by spacing or approximation of their free ends 16 ( Figure 3)
- Figures 5 and 7 show the type of stack (equilateral triangle) obtained with open rings 10".
- the internal diameter of the rings of the inner layer is substantially equal to or slightly greater than the outer diameter of the mandrel 12, and the outer diameter of these rings is greater than the internal diameter of the rings of the outer layer, which forces the rings of the outer layer. to adopt a position in which they are located between two rings of the inner layer, outside of them ( Figure 5).
- Each ring of the outer layer is located in a transverse plane passing substantially in the middle of two transverse planes passing respectively through the two adjacent rings of the inner layer.
- Figure 7 shows the half-cross sections of three adjacent rings distributed over two layers, an inner layer formed of two rings and an outer ring located outside and between the rings of the inner layer.
- the stack is of the equilateral triangle type because the centers of the (circle-like) sections of the wires are located at the corners of an equilateral triangle.
- the expansion of this stack is of the order of 9.31%.
- the rings 10 "are stacked on the mandrel so that their openings are angularly offset relative to each other about the axis A. These openings can thus be evenly distributed or not around the axis A , which avoids the creation of areas where the metal would fail and voids may appear during the compression phase.
- the inner layer of metal rings 10 is surrounded by a composite fibrous structure which may consist of a fabric or a ply of ceramic fibers 18 coated with metal.
- the fiber coating metal 18 and the metal of the metal rings 10 are preferably identical in nature (in TiA6V or 6242 for example) to optimize the subsequent step of the process relating to the hot isostatic pressing operation and diffusion welding.
- the fabric or the ply of fibers 18 is wound on the first layer of metal rings 10 so that the fibers extend parallel to the axis A of the mandrel 12.
- a winding of several tissues or plies can be provided to from the same tissue, or from one or more other separate tissues wound coaxially.
- the fabrics can be of different species and different diameters of coated fibers.
- the length of the composite fibrous structure is less than or equal to the length L of the first layer of metal rings 10.
- the fibers 18 may be wound around the mandrel and extend circumferentially about the axis A.
- coated ceramic fibers may be any coated ceramic fibers.
- the coated ceramic fibers may be any suitable coated ceramic fibers.
- SiC / Ti SiC / Al, SiC / B, etc.
- a next step of the method according to the invention shown in Figure 8 is to cover the aforementioned fibrous structure of at least one other layer of metal rings 10, these metal rings being stacked around the mandrel 12 as indicated in the foregoing.
- Metal rings 10 are furthermore arranged in front of and behind the fibrous structure so that it is embedded in the metal of the final piece to achieve.
- a blank E of the part was thus gradually formed around the mandrel.
- This blank E may comprise more than one thousand rings and several fibrous structures of the aforementioned type, these fibrous structures being separated from each other by at least one layer of metal rings.
- the blank E is then subjected to a hot isostatic pressing treatment (CIC or HIP) under an isothermal press or in an autoclave bag (the choice depending in particular on the number of parts to be produced).
- CIC hot isostatic pressing treatment
- HIP hot isothermal press
- autoclave bag the choice depending in particular on the number of parts to be produced.
- the blank is set up in a suitable tool (FIG. 9) and a strong compression is exerted on the blank at an appropriate elevated temperature so that the metal of the rings and the fiber coating soften and flow. by filling all the empty spaces between the rings of the different layers until the connection of the different elements by welding diffusion.
- the blank is placed in a deformable bag of mild steel which is then introduced into an autoclave.
- This autoclave is brought to an isostatic pressure of 1000 bar and a temperature of 940 ° C (for TiA6V), so that the entire bag deforms by retracting by evacuation of the air and applies to the blank a uniform pressure until the creep of the metal with bonding by diffusion welding.
- the method according to the invention makes it possible to produce non-circular shaped section pieces, for example with a pentagonal (FIG. 10), rectangular (FIG. 11) or triangular-shaped section (FIG. 12).
- the preforming step of the method according to the invention then consists in preforming the rings to give them a shape of the desired type, these rings being engaged and stacked on a mandrel section complementary shape.
- rectangular-shaped rings are engaged on a parallelepipedal mandrel of rectangular section, for producing a one-piece piece of rectangular section such as that shown in Figure 1 1.
- These rings may be closed or non-split as well as open or split type.
