Definitions
- the invention relates to a metal part having an annular portion including a coaxial annular fiber reinforcement, in the form of a coil of composite material enclosed in a metal matrix.
- the invention relates more particularly to the manufacture of such a piece with improved strength. It also relates to a metal part enclosing such a coaxial annular reinforcement.
- the ceramic is, for example, silicon carbide wire which has a tensile or compressive strength greater than that of a metal, such as titanium for example.
- the document FR 2 886 290 proposes to carry out the winding directly on a part of the blank forming the winding mandrel. It is therefore an "external" winding of the most classic. More precisely, this part has two shoulders. The radially innermost shoulder forms a lateral bearing surface for the winding. The adjacent cylindrical portion forms the base surface on which the winding is made. It has a rectangular shape in right cross section. After winding, complete the blank by complementary metal parts, including an outer ring and a side cover having a pin coming into contact with the winding.
- the hot isostatic pressing operation is known per se; it consists of placing the aforementioned assembly in a box and subjecting this assembly, for several hours, to a high pressure of the order of 1000 bar and at a temperature of the order of 1000 0 C. After this operation , the piece, of a single block, is machined to the desired shape and dimensions.
- the different parts of the blank and the sheathing of the ceramic wire are of the same metal so that the finished part is provided with a wound composite insert embedded in a homogeneous metal matrix.
- the zone reinforced by the winding has a generally rectangular cross section.
- this reinforced area surrounded by exclusively metal parts, occupies as large a volume as possible.
- This rectangular cross section insert arrangement may not be completely satisfactory in the direction of the forces applied to the workpiece. While the strength of the fibers is excellent tangentially both in tension and in compression, it is lower than that of pure metal when the forces are applied in a direction transverse to the fibers. By way of examples, this is particularly the case when the annular part thus produced is a rotating part equipped with vanes, such as a turbine disk, in particular for an airplane turbojet engine. Another piece subjected to transverse forces is the "rotating sleeve" connected to jacks in a landing gear mechanism. With a part provided with a winding with a rectangular straight cross-section, breaks are possible in the outer part of the reinforced zone.
- the basic idea of the invention is to establish a "zone of progressivity" of pure metal in this outer radial region, laterally between the periphery and the zone where the turns are located.
- a coiled portion having a trapezoidal or triangle-shaped cross-section at least in its radially outermost portion is capable of responding to the data of the problem.
- a half wave shape may also be considered provided that the proportion of pure metal increases radially outwardly of the workpiece, all other things being equal.
- Another difficulty is then to make the part because the "external" winding as described above is difficult to envisage.
- the invention also proposes a new approach to winding, called “internal winding”.
- the invention relates to a method for manufacturing an annular axisymmetric metal piece reinforced by inclusion therein of a coaxial annular reinforcement in the form of a composite material coil, characterized in that it comprises the steps of ;
- annular metal blank of said part - practice or complete a cavity opening on a coaxial inner face of said blank and having a right cross section of axial length decreasing radially outwardly over at least a part of its height
- the reinforcing wire is composed of a ceramic core, sheathed with metal.
- the shape of the coil thus obtained that is to say, in fine, the shape of the zone provided with ceramic fibers makes it possible to reserve radially outwards of said zone and on either side thereof larger masses of pure metal (titanium for example) allowing a substantially radial force to be transferred "progressively" in the fibers along directions turning it into an effort more and more oriented tangentally
- the coil can be stabilized during its formation by welds joining certain turns together by their metal sheath.
- the winding of the reinforcing wire is initiated by fixing an end thereof to the bottom of the cavity and the winding is continued by rotating the blank about its axis while feeding the wire at a controlled speed with respect to the speed of rotation of the blank.
- the feeding speed of the wire is such that it urges said blank in the direction of rotation thereof.
- FIGS. 1, 2, 3A and 4 to 6 illustrate, by cross-sectional views, the various steps of the method of manufacturing an annular axisymmetric metal piece reinforced by winding a reinforcing wire;
- FIG. 3B is a partial perspective view illustrating the phase of FIG. 3A;
- annular piece such as a rotor disc
- metal blank 11 for example titanium
- axisymmetric here cross section rectangular right
- this section may have a different shape depending on the geometry of the final part that is desired.
- the blank has a coaxial inner face 12, here cylindrical.
- Figure 2 consists in practicing, in the mass of the blank, for example by machining, a cavity 14 opening (opening) on said coaxial inner face 12.
- the blank can be rotated about the X axis and introducing a cutting tool through the accessible central portion of said blank. Material is removed until an annular cavity opens on said coaxial inner face of the blank. Note It is possible to start from an already hollow blank, the machining operation simply being to complete the cavity for Iu! give the shape and dimensions.
- the cavity 14 has a right cross section of axial length decreasing radially outwardly over at least a portion of its height.
- the cavity has (in a straight cross-section and in a radial direction from inside to outside) a rectangular shape 15 extended by a trapezoidal shape 16.
- This second portion of the cavity could have a triangular shape or any other form whose axial length (along the X axis) decreases from the inside to the outside.
- This operation is carried out by introducing the wire through the opening of the cavity and depositing it from the cylindrical bottom 23 of the cavity by adjacent turns then by successive layers of turns until they are completely filled. the whole space of the cavity, by a coil of contiguous turns 25.
- the wire is fed via a rigid tubular guide 27 movable in a controlled manner parallel to the X axis (to form a layer) and radially recessed (to develop the following successive layers).
- the guide 27 is oriented as shown in Figs. 3A and 3B, i.e., its end 27a is at a small angle to the circumferential winding direction of the turns.
- the winding of the wire 21 is initiated by fixing (by welding) one end thereof to the cylindrical bottom wall 23 of the cavity, near one end thereof, and the blank 11 is rotated around its end.
- X axis, and feeding the wire at a controlled speed relative to the speed of rotation of the blank It is possible, for example, to continuously adjust the speed at which the wire 21 is brought so that this speed is always substantially equal to the winding speed. taking into account the speed of rotation of the blank and the diameter of the layer of turns during winding.
- the feed speed of the wire is such that it solicits the roughing in the direction of rotation of the latter.
- the wire 21 may be pushed inside the guide 27 by a drive rotary roller drive system (not shown) with possibility of longitudinal sliding so that said wire is in slight compression between its output of the guide 27 and the point where it takes its place in the winding.
- the blank 11 is mounted in free rotation and that it is the stress exerted on the wire itself which drives it in rotation during the winding.
- the turns are stabilized at given winding intervals, by welding points or lines joining the metal sheaths of certain turns.
- the weld can be an electrical or induction weld, under vacuum or in a neutral atmosphere of argon.
- a welding process as described in FR 2 886 290 can be implemented.
- FIG. 4 consists of closing the cavity 14 filled by the coil 25.
- a cylindrical metal wall 30, here made of titanium is placed in register with the opening of the cavity.
- This wall here has the same length as the axial length of the opening so that during hot isostatic compression, it can deform radially outwardly penetrate the cavity, compacting the winding itself.
- the cylindrical annular wall 30 can be dimensioned so that its diameter is slightly greater than that of the central opening of the blank but while carrying this annular wall at a low temperature (by dipping it in liquid nitrogen, for example ) before putting it in place.
- the annular wall 30 engages the cavity by starting to compact the coil.
- the closure of said cavity comprises its evacuation with hermetic closure by a welded metal sheet 32.
- This metal sheet is welded on both sides of the opening of the cavity, before the hot isostatic pressing operation.
- the actual hot isostatic pressing operation is then carried out, consisting, for example, in placing the blank, modified as shown in FIG. 4, in a box for several hours, bringing the pressure to 1000 bar and the temperature to be reached. 1000 0 C, approximately.
- FIG. 5 It can be seen that the annular wall 30 is engaged in the cavity, driving the metal foil 32.
- the assembly forms only a single block with a large part of the volume occupied by a winding. high strength ceramic wire, embedded in a metal matrix resulting from the melting of the metal sheath of the wire used during winding.
- a series of machining operations (FIG. 6) are then carried out, with the purpose of defining, from the blank transformed by the hot isostatic pressing operation, the contour of the desired part (shown in dashed line in FIG. 6). ).
- the final piece 36 of FIG. 7 comprises purely metallic external lateral zones (17a, 18a), making it possible to increase the transverse mechanical strength of the part and locally to limit the breaks of stiffness favoring breaks. These so-called “progressivity" zones have the effect of bringing the efforts gradually, by shearing, into the fibrous reinforcement (the winding) in order to convert the forces in tension / compressive strength for which the resistance of the wound zone is optimal.
