Definitions

  • the object of the invention is a superalloy powder.
  • a second powder of nickel (Ni) or cobalt (Co) base containing 2 to 6% by weight of fusing elements such as boron (B) or silicon (Si).
  • the presence of fusing elements in the second powder makes it possible to lower the melting point of the latter and to work at a temperature at which the second powder is liquid, while the first powder remains in the solid state.
  • bi-component mixtures nevertheless have a number of drawbacks such as the difficulty of making a uniform mixture of two powders, problems of segregation of the powders during storage of the mixture, or problems of proportioning each powder in the mixture.
  • drawbacks such as the difficulty of making a uniform mixture of two powders, problems of segregation of the powders during storage of the mixture, or problems of proportioning each powder in the mixture.
  • a porous sintered material is obtained.
  • an excess of fusing element in certain regions of the mixture causes excessive fusion resulting in deformation of the sintered material, which then fails to conform to the required dimensions.
  • a solution described in FR 2 822 741 envisages a means of incrusting the grains of the second powder onto the grains of the first powder by mechanical synthesis.
  • this incrustation technique is found to be limited: this technique is found to be rather difficult to put into effect, in particular by virtue of the fineness of the second powder used, which causes health problems. Moreover this technique only partially improves the homogeneity.
  • the purpose of the invention is to propose an alternative to the existing solutions, offering good results in terms of uniformity of distribution of the fusing element(s) within the powder, which is reflected in particular by the absence of deformation of components fabricated by sintering.
  • the object of the invention is a Ni— or Co-based 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, as the powder of the invention already has the final composition that is needed, both in terms of constituent elements of the superalloy and in terms of fusing element(s).
  • the proportion of B and, optionally, of Si is adapted for utilization of the powder without a step of preliminary mixing with another powder (as explained above, the proportion of fusing elements has a determining influence on the behavior of the powder during heat treatment of the latter).
  • said fusing element forms an integral part of the superalloy: it is not chemically deposited or mechanically incrusted on the surface of the superalloy grains, as in the known techniques referred to above.
  • the constituent elements of the superalloy, including the fusing element are present in each grain of powder and are therefore distributed within the powder in a perfectly homogeneous manner.
  • the problems of localized porosity and excessive fusion, associated with too low a proportion or too high a proportion of fusing element in certain regions of the powder, are thus avoided.
  • the powder of the invention use is made of a technique of atomizing a precursor liquid mixture, including the elements of said superalloy and said at least one fusing element.
  • FIG. 1 is a photograph of a plate made by sintering from a powder according to the invention.
  • FIG. 2 is a photograph of a plate made by sintering from a bi-component mixture of powders.
  • each powder is a Ni— or Co-based superalloy powder which includes at least the three elements Ni, Co and Cr (chromium).
  • These powders were made using an atomization technique from a precursor liquid mixture including the elements of the superalloy (Ni, Co, Cr . . . ) and at least one fusing element (B and, optionally, Si).
  • This liquid mixture was obtained by fusing alloys by induction, under vacuum, in a crucible equipped with a burette allowing the liquid mixture to flow out at a low rate of flow.
  • Inert gas jets under high pressure, flowing at a velocity close to that of sound, are used to atomize the mixture leaving the burette.
  • the mixture then breaks down into fine droplets which then assume a spheroidal shape under the effect of surface tension and cool down very rapidly in an atomization chamber.
  • the inert gases used are argon or nitrogen for example.
  • the superalloy enriched with fusing elements essentially includes: 14 to 19.6% of Co; 8.2 to 15.3% of Cr; 2.6 to 4.7% of Mo; 2.25 to 3.5% of Al; 1.95 to 3.1% of Ti; 0 to 2% of Si; 0.4 to 1.3% of B; and a remainder of Ni.
  • carbon (C), zirconium (Zr), and phosphorus (P) may be found in minimal proportions, for example in the order of, or less than, 0.06%.
  • the superalloy enriched with fusing elements essentially includes: 16.4 to 19.6% of Co; 8.2 to 12.8% of Cr; 2.6 to 4.4% of Mo; 2.25 to 3.3% of Al; 1.95 to 2.9% of Ti; 0.8 to 2% of Si; 0.5 to 1.3% of B; and a remainder of Ni.
  • the enriched superalloy essentially includes: 14 to 16% of Co; 12 to 15.3% of Cr; 3.35 to 4.7% of Mo; 2.9 to 3.5% of Al; 2.5 to 3.1% of Ti; 0.4 to 1% of B; and a remainder of Ni.
  • B is the sole fusing element.
  • the enriched superalloy in a second type of superalloy powder according to the invention, based on Co, essentially includes: 17.2 to 22.2% of Cr; 26.75 to 30% of Ni; 0 to 1.5% of Si; 0.8 to 1% of B; 0.1 to 0.5% of C; 0 to 0.37% of Zr; 0 to 3% of Ta; and a remainder of Co.
  • the cobalt-base powders of the second type can include impurities, such as phosphorus P, in minimal proportions, for example in the order of, or less than, 0.04%.
  • Table 1 summarizes the compositions of the example powders (a) and (b), cited above, and of an example powder (c) corresponding to the second type of superalloy powder according to the invention.

  • All of these examples of superalloy powder may be used in the implementation of any brazing-diffusion method applied during the manufacture or repair of components made of nickel-based or cobalt-based alloys, in particular in the field of aeronautical engineering. This can include assembly of components, filling of cracks, or fissures, on a component or hardfacing of the surface of a component with a view to correcting a superficial defect or restoring certain properties or geometric dimensions of the latter.
  • placement of the filler powder can be effected in different ways.
  • the raw powder can be used mixed with a cement, for example of the type Nicrobraz 320. It will be noted that the mixture obtained can be applied in the form of beads.
  • the application can be effected in the form of a compact filler piece.
  • Said compact filler piece is obtained from the powder either by a fabrication technique imparting compaction by sintering the powder, or by techniques of injection molding of metallic powders.
  • FIG. 1 shows an example of a compact filler piece made by sintering from a superalloy powder according to the invention. It takes the form of a plate designed to be used to build up the surface of a component.
  • This plate was made from a powder of the first type cited above, according to the following steps: kilning of the raw powder; distribution of the latter in a mold matching the dimensions and thickness of the desired sintered material; arrangement of the mold in a furnace to expose it to heat treatment.
  • heat treatment it is possible to apply (for a furnace pressure of 0.13 Pa) a progressive temperature rise to 1,160° C., holding at this temperature for approximately 10 minutes, followed by gradual cooling.
  • FIG. 2 shows the piece obtained.
  • the invention made it possible to dispense with the handling and storage of several different types of powders, and to avoid any powder mixing stage, which is critical from a health and safety perspective.
  • the sintering temperature is substantially reduced relative to the temperature required for a bi-component mixture.
  • FIG. 2 illustrates the deformation problems that may be encountered during sintering of a bi-component mixture.
  • the homogeneity of the superalloy powder of the invention is also reflected in an improvement in the mechanical properties of the zone built up using said plate.
  • a compact filler piece can be made using known techniques of injection molding of metallic powder. These techniques generally make it possible to obtain components of more complex shapes than those made by simple molding followed by sintering.
  • the powder is mixed with a binder in a mixer.
  • the binder includes, for example, polypropylene, ethylene, vinyl acetate and paraffin.
  • the mixing time must be such that plastification of the mixture is obtained.
  • the mixture is then cooled before being milled.
  • the granular material thus obtained can be fed into the hopper of a press and injected into molds of dimensions specific to the compact filler piece to be produced.
  • the molded blank is then chemically stripped from the mold and said blank is sintered.
