Definitions
- the invention relates to the field of manufacturing the leading edge for organic matrix composite (CMO) fan blades.
- CMO organic matrix composite
- Document FR1051992 describes a known method of manufacturing such a blade. This method takes place as follows: two sheets, intrados and extrados, formed, are shaped, via an isostatic hot compaction operation, around a core of refractory alloy whose geometry corresponds to the internal geometry of the desired leading edge . After shaping, the core, which is a reusable tool, is removed and the leading edge is machined only on its outer surfaces to obtain the final geometry of the part.
- the latter must have three main characteristics in relation to the fact that the shaping step is carried out via a thermomechanical cycle at high temperature, of the order of 800 - 1000 ° C., during which, the core is in contact with the elements of the leading edge in titanium for several hours:
- the core must be non-deformable in the thermomechanical range of manufacture of the leading edge in order to ensure the shape of the internal cavity of the leading edge
- the core must not allow any chemical reaction between its material and the material of the leading edge
- the core must not allow any adhesion or bonding between its material and the material of the leading edge
- the second avoids or minimizes chemical decontamination of the surfaces of the internal cavity of the leading edge.
- the metal alloys retained for the core are nickel-based or cobalt-based alloys so as to be rigid enough not to deform during conforming cycles at high temperature.
- this type of alloy brought into contact at high temperature with the titanium alloys of the part are reactive with one another and form solid solutions or intermetallic compounds, which leads at best to contamination of the titanium alloy, worse an unacceptable bond between nickel / cobalt and titanium.
- a technical solution consists in interposing an anti-diffusion barrier between the two metallic alloys in contact that are the nickel or cobalt base alloy of the core and the titanium alloy of the leading edge which will undergo a thermomechanical treatment at high temperature for many hours.
- a method described by the document FR 1653221 is the production of nitriding or nitro-carburization of the nickel or cobalt base core. This treatment generates a surface layer rich in nitrogen and carbon of a few tens of microns on the surface of the core ensuring the role of anti-diffusion barrier.
- the invention provides a method of manufacturing a core for the production of a leading edge of a fan blade, characterized in that it comprises the steps of:
- the cobalt-based alloy may include carbon.
- the cobalt-based alloy can comprise between 26% and 32% of molybdenum, between 7% and 20% of chromium between 1% and 5% of silicon and less than 1% of carbon.
- the cobalt-based alloy can comprise between 25% and 35% of chromium, between 0% and 10% of tungsten, between 0% and 7% of molybdenum, between 0% and 4% of nickel, between 1% and 3% of silicon and less than 2% carbon.
- the cobalt-based alloy can comprise between 28% and 30% of chromium, between 1.2% and 1.6% of carbon and, between 1.2% and 1.8% of silicon.
- the deposited layer may have a thickness of 100 microns and 2 millimeters, preferably 500 microns.
- the method may further comprise, following step (b) of thermal spraying, a step (d) of machining by rectification.
- the method may further comprise, following step (b) of thermal spraying, a step (e) of air heat treatment, comprising a first stage of approximately thirty minutes at a temperature between 300 ° C and 400 ° C, a second stage of approximately thirty minutes at a temperature between 500 ° C and 700 ° C, a third stage of approximately thirty minutes at a temperature between 800 ° C and 1000 ° C, and cooling to ambient air, to oxidize the layer.
- step (e) of air heat treatment comprising a first stage of approximately thirty minutes at a temperature between 300 ° C and 400 ° C, a second stage of approximately thirty minutes at a temperature between 500 ° C and 700 ° C, a third stage of approximately thirty minutes at a temperature between 800 ° C and 1000 ° C, and cooling to ambient air, to oxidize the layer.
- Figure 1 is a microscopic sectional view of the surface of a core according to the invention.
- FIG. 2 is a block diagram of a method according to the invention.
- the invention relates to a process for manufacturing a core 1 for the production of a leading edge of a fan blade, the process essentially comprises the steps of:
- step (a2) the initial core 11 can be cleaned and degreased. This step guarantees a surface condition of the initial core 11, which is optimal for the next projection step (b).
- step (b) consists in the thermal spraying onto the initial core 11 of a layer 12 of a cobalt-based alloy, comprising chromium and at least one element from tungsten and / or molybdenum. It is specified that tungsten, molybdenum and chromium can be present in the form of carbide.
- the cobalt base alloy can have the following composition, in mass percentage: between 26% and 32% of molybdenum, between 7% and 20% of chromium, between 0% and 10% of tungsten, between 1% and 5% silicon and less than 1% carbon.
- the cobalt-based alloy can comprise 28% of chromium, 5.5% of molybdenum, 2.5% of nickel, 2% of silicon and 0.25% of carbon.
- the cobalt-based alloy can comprise 29.5% of chromium, 8% of tungsten, 1.5% of silicon and 1.4% of carbon.
- the cobalt-based alloy can comprise between 26% and 32% of molybdenum, between 7% and 20% of chromium between 1% and 5% of silicon and less than 1% of carbon.
- the cobalt-based alloy can comprise 29% of molybdenum, 8.5% of chromium, 2.6% of silicon and less than 0.08% of carbon.
- the cobalt-based alloy can comprise 28% of molybdenum, 18% of chromium, 3.4% of silicon and less than 0.08% of carbon.
- the thermal projection of these types of alloys provides chemical inertness which makes it possible to produce an anti-diffusion barrier between the initial core 1 1 made of a nickel base alloy and sheets made of titanium used for the manufacture of the fan blade.
- the layer can be projected by blown arc plasma.
- This method leads to a porous layer but having good mechanical grip on the surface of the core.
- This method can optionally consider vacuum pumping during projection.
- the layer can be deposited by a plasma torch according to the so-called “Plasma Transferred Arc” (PTA) method.
- PTA Plasma Transferred Arc
- the method can include a rectification step (d) to reduce a thickness of the layer 12.
- the layer 12 can have a thickness of between 100 and 500 microns. This step can also serve as a practical verification of the adhesion of the deposit.
- the method may include a step (e) of air heat treatment, comprising a first stage of approximately thirty minutes at a temperature between 300 ° C and 400 ° C, a second stage d 'about thirty minutes at a temperature between 500 ° C and 700 ° C, a third stage of about thirty minutes at a temperature between 800 ° C and 1000 ° C, and cooling in ambient air.
- a step (e) of air heat treatment comprising a first stage of approximately thirty minutes at a temperature between 300 ° C and 400 ° C, a second stage d 'about thirty minutes at a temperature between 500 ° C and 700 ° C, a third stage of about thirty minutes at a temperature between 800 ° C and 1000 ° C, and cooling in ambient air.
- the layer 12 can have a hardness of between 35 and 65 HRC, preferably between 45 and 55 HRC. It is specified that the hardness is expressed and measured according to the so-called Rockwell test, using a penetrator to which an initial charge is applied and then an additional charge. Hardness is measured by comparing the depth of penetration of the indenter when applying the initial load and when applying the additional load. For the HRC scale, In this case, the test is carried out with a penetrator consisting of a diamond cone of circular section with a spherical rounded point of 0.2 millimeters. In addition, the initial charge applied is 98N and the total charge (corresponding to the initial charge plus the additional charge) is 1471.5N. One HRC hardness unit corresponds to a penetration of 0.002 millimeters.
- the HR15N scale is preferred because the initial load applied is only 29N and the total load (corresponding to the initial load plus the additional load) is only 147.1 N.
- the invention relates to a core 1 of nickel base alloy obtained by a method according to the invention.
- the core 1 has a layer 12 composed of a cobalt base alloy comprising chromium and at least one element from tungsten and / or molybdenum obtained by thermal spraying of a cobalt base alloy comprising chromium and at least one element from tungsten and / or molybdenum.
