Definitions

  • the subject of the invention is a superalloy powder.
  • the presence of melting elements in the second powder makes it possible to lower the melting point thereof and to work at a temperature at which the second powder is liquid, while the first powder remains in the solid state.
  • the aim of the invention is to propose an alternative to existing solutions, offering good results in terms of homogeneous distribution of the melting element or elements within the powder, which results, in particular, in the absence of deformation of the parts made by sintering.
  • the subject of the invention is a superalloy powder according to claim 1 or claim 5.
  • the powder of the invention It is not necessary to mix the powder of the invention with another powder as in FR 2 822 741 because the powder of the invention already has the final composition which is needed, both in terms of constituent elements of the superalloy and in terms of element (s) melting (s).
  • the proportion of B and, optionally, Si is adapted for use of the powder without prior mixing step with another powder (as explained above, the proportion of melting elements has a determining influence on the behavior of the powder during the heat treatment thereof).
  • said melting element is an integral part of the superalloy: it is not chemically deposited or mechanically inlaid on the surface of the superalloy grains, as in the known techniques mentioned above.
  • the constituent elements of the superalloy including the melting element, are present in each grain of powder and, consequently, are distributed within the powder in a perfectly homogeneous manner. This avoids the problems of localized porosity and supercooling related to a too low proportion, or too important, element melting in some regions of the powder.
  • a technique for atomizing a precursor liquid mixture comprising the elements of said superalloy and said at least one melting element.
  • each powder is a base Ni or Co superalloy powder, which comprises at least the three elements Ni, Co and Cr (Chrome).
  • These powders were made using an atomization technique from a precursor liquid mixture comprising the elements of the superalloy (Ni, Co, Cr ...) and at least one melting element (B and optionally Si).
  • This liquid mixture was obtained by melting alloys by induction, under vacuum, in a crucible equipped with a burette allowing the liquid mixture to flow at a low flow rate. Jets of inert gases under high pressure, flowing at a speed close to that of the sound, are used to spray the mixture leaving the burette. The mixture then disintegrates into fine droplets which then take a spheroidal shape under the effect of the surface tension and cool very rapidly in an atomization chamber.
  • the inert gases used are, for example, argon or nitrogen.
  • base Ni the superalloy enriched in melting elements, essentially comprises:
  • carbon (C), zirconium (Zr), and phosphorus (P) may be found in minute proportions, for example, on the order of 0.06% or less.
  • the superalloy enriched in melting elements essentially comprises: 16.4 to 19.6% of Co; 8.2 to 12.8% Cr; 2.6 to 4.4% Mo; 2.25 to 3.3% AI; 1.95 to 2.9% Ti; 0.8 to 2% Si; 0.5 to 1.3% B; and a balance in Ni.
  • the enriched superalloy essentially comprises: 14 to 16% of Co; 12 to 15.3% Cr; 3.35 to 4.7% Mo; 2.9 to 3.5% AI; 2.5 to 3.1% Ti; 0.4 to 1% of B; and a balance in Ni.
  • B is the only melting element.
  • the enriched superalloy essentially comprises: 17.2 to 22.2% of Cr; 26.75 to 30% Ni; 0 to 1.5% Si; 0.8 to 1% of B; 0.1 to 0.5% C; 0 to 0.37% Zr; 0 to 3% of Ta; and a balance in Co.
  • the cobalt base powders of the second type may comprise impurities, such as phosphorus P, in minute proportions, for example of the order of 0.04% or less.
  • Table 1 shows the compositions of the examples of powders (a) and (b), mentioned above, and of an example of powder (c) corresponding to the second type of superalloy powder according to the invention.

  • superalloy powder can be used in the implementation of any solder-diffusion process applied during the manufacture or repair of nickel-based alloy parts, cobalt, especially in the aeronautical field. It can be an assembly of parts, a filling of cracks, or cracks, on part or a reload of part surface to correct a superficial defect or to restore certain properties or geometrical dimensions of that -this.
  • the introduction of the filler powder can be carried out in different ways.
  • the raw powder can be used mixed with a cementum, for example of the Nicrobraz 320 type. It will be noted that the mixture obtained can be used in the form of cords.
  • a supply can be made in the form of a compact filler.
  • Said compact filler is obtained from the powder either by a manufacturing technique ensuring a sintering compaction thereof, or by means of injection molding techniques of metal powders.
  • FIG. 1 shows an example of a compact filler piece made by sintering from a superalloy powder according to the invention. This is a plate intended to be used to reload the surface of a room.
  • This plate was made from a powder of the aforementioned first type, according to the following steps: oven drying of the raw powder; distribution thereof in a mold adapted to the desired size and sintered thickness; placing the mold in an oven to heat treat it.
  • heat treatment one can perform (for an oven pressure of 0.13 Pa) a gradual increase in temperature up to 1160 ° C, then a hold at this temperature for about 10 min, followed by a gradual cooling.
  • the invention makes it possible to avoid the management and storage of several references of powders, and to avoid any step of mixing powders, critical from a hygiene and safety point of view.
  • the sintering temperature is significantly reduced. relative to the temperature required for a two-component mixture. Thanks to the homogeneity of the powder and the reduction of the sintering temperature, a noticeable improvement in the homogeneity of the properties of the sintered plate and a good preservation of the dimensions and the shape thereof, in particular a respect of the wished dimensions and a good flatness.
  • Figure 2 illustrates, conversely, the deformation problems that can be encountered during sintering of a two-component mixture.
  • the homogeneity of the superalloy powder of the invention also results in an improvement of the mechanical properties of the zone reloaded with said plate.
  • the powder is mixed with a binder in a kneader.
  • the binder includes, for example, polypropylene, ethylene, vinyl acetate and paraffin.
  • the mixing time must be such as to obtain a plasticization of the mixture.
  • the mixture is then cooled before being ground.
  • the granulates thus obtained can be introduced into the hopper of a press and the injection can be carried out in molds of dimensions specific to the compact part to be produced.
  • the mold blank is then chemically untied and the blank is sintered.
