Definitions

  • the present disclosure relates to a method of manufacturing a part covered with an abradable coating.
  • machines include moving parts that rub or otherwise rub against other parts.
  • some machines comprise a moving part rotated relative to an axis, a part of this moving part rubbing against another part.
  • turbomachines terrestrial or aeronautical, such as turbojets or turbine engines
  • turbomachines which comprise a rotor with moving blades which, in their rotational movement, rub against the inner face of the housing of the stator which surrounds them.
  • the solution currently used is to bring the blades as close as possible to the casing and to cover the casing with a coating of soft material in front of the blades.
  • This material is abradable, which means that it has the property of being easily dug by the end of the blades in case of contact.
  • a dawn is virtually undamaged when it rubs against this material abradable and optimizes the space between the end of the blade and the inner surface of the housing by adjusting this space to a minimum in time.
  • the present invention aims to remedy, at least in part, these disadvantages.
  • the blank provided is advantageously rough hot forming (forging, rolling ...), that is to say that the blank has not yet been hot shaping.
  • the housing can, meanwhile, be already formatted hot and / or machined.
  • the co-rolling achieved allows local application of hot compression on the abradable material. Typically, it is a unidirectional compression hot, normal to the inner surface of the blank. This hot compression makes it possible to sinter and compact the abradable material and to adhere it to the blank by welding-diffusion.
  • the hot compression applied by the co-rolling is sufficient to sinter and compact the abradable material and adhere it to the blank, and the manufacturing method does not include any hot pressing step before or after the step of co-rolling.
  • Such a method makes it possible to obtain good compaction and good cohesion of the particles of the abradable material.
  • the adhesion of the particles to the blank is good and the solder interface between the material and the blank has little or no porosity. The risk of subsequent detachment of the abradable coating is decreased.
  • the blank and the abradable material can be shaped closer to the dimensions of the final piece, for example with straight mandrels or shaped mandrels.
  • the housing opens on the surface of the blank via an opening (s). During co-rolling, pressure is exerted on the abradable material through this (these) opening (s).
  • said housing is filled with the abradable material by this (these) opening (s) during the filling step (step B) and this (these) opening (s) is sealed with a sheath, before the co-rolling step (step C).
  • steps D to F are performed after step A and before step C above, step E returning to step B.
  • the co-rolling step C comprises a first preheating step C1 during which the blank is heated to a rolling temperature T, the sintering of the abradable material taking place, at least in part, during this first step, and a second step C2 during which the blank is co-laminated and the abradable material at the rolling temperature T.
  • the rolling temperature (and, more generally, the thermomechanical cycle of the part) will be defined according to the smallest domain of forgeability taking into account the adiabatic warming and the domain leading to the desired microstructures of the considered materials.
  • the maximum temperature will be the limit of overheating or burning of one of the shaped materials and the minimum temperature will be the limit of microstructural damage of one of the materials.

  • the rolling temperature T can be between 850 ° C and 1250 ° C. If the material is a titanium alloy, the rolling temperature T may be between 700 ° C and 1150 ° C. For titanium alloys known as TA6V with a controlled alpha + beta structure, the rolling temperature T may be between 700 ° C. and 1050 ° C., and advantageously a temperature T of around 950 ° C. is used. For titanium alloys known as TA6V with a beta controlled structure, the rolling temperature T may be between 1050 ° C. and 1150 ° C., and advantageously a temperature T of about 1100 ° C. is used.

  • the abradable material in its pulverulent form, comprises base particles which, after co-rolling (Step C) constitutes the matrix of the abradable coating, and secondary particles facilitating the fragmentation of the abradable coating.
  • the secondary particles facilitate the fragmentation of the abradable coating during friction with the moving part, and thus the adjustment of the clearance between the moving part and the coating.
  • organic secondary particles can be introduced into the mixture of particles. Such particles will decompose during the co-rolling operation by forming gas porosities. These porosities facilitate the fragmentation of the coating.
  • the abradable material also includes hard, wearable particles, allowing, in operation, a slight polishing of the moving parts.
  • the housing has concave side faces (towards the interior of the housing). This makes it possible to trap the abradable coating without generating residual stresses in it or at least to distribute the stresses at the interface between the abradable coating and the substrate, which makes it possible to limit the detachment.

During sintering, it does not necessarily occur melting of the material constituting the particles. In a sintered material, there may therefore remain porosities.

  • These secondary particles 52 facilitate the stalling of pieces of abradable coating 55 to the passage of the moving part 60 with which the part 1 interacts.
  • the secondary particles 52 may have two modes of action. Either these particles 52 resist co-rolling and remain in solid form in the matrix of the abradable coating 55, thus creating irregularities that weaken the structure of the matrix.
