  • the hard particles remain unchanged due to their high strength and low ductility in the matrix.
  • the incorporation rate of hard materials with proportions of more than 20% is not possible. Namely, the hard material particles do not automatically adhere to the surface of the substrate to be coated, since the kinetic energy input of the cold gas spraying is insufficient and the particles do not have sufficient ductility. Rather, the particles of hard material are incorporated into the just that forms the matrix of the me ⁇ -metallic material with, so that the adhesion in- is ensured directly by the component with the lower strength or higher ductility.
  • the object of the invention is to provide a method for cold gas spraying, with which, when using particles of different types, those particles having the higher strength and / or low ductility with a comparatively high layer proportion can be brought into the layer.
  • This object is achieved in that the particles of the first kind are fed in a first region of the stagnation ⁇ onshunt, which is closer to the nozzle, as a second region in which the particles of the second type are fed.
  • This energy input is primarily caused by the preheated Trä ⁇ gergas the cold gas jet. Namely, a temperature compensation takes place between the molecules of the carrier gas and the particles located in the stagnation chamber. The ⁇ water is the stronger, the longer the particles remain in the stagnation chamber.
  • the energy input into the particles of the second type RESIZE ⁇ SSER advantageously improves the conditions for a separation of the particles of the second type.
  • the additional heating of the stronger or less ductile particles can, as has been shown, influence the coating process in different ways.
  • the particles of the second kind of a brittle material, in particular of a ceramic material can be produced.
  • Tungsten carbide is particularly suitable as a ceramic material, it being possible to deposit it on the blade of a compressor or a turbine in order to increase its service life.
  • the additional heating of brittle materials in the stagnation chamber basically does not change their properties. Nevertheless, it has been shown that the heated Parti ⁇ kel allow higher incorporation rates in a ductile matrix. This is explained by the fact that the particles of the second type are used as thermal energy stores, this thermal energy improving the interaction between the particles of the first and second type at the moment of incorporation of the brittle particles into the ductile matrix. The contribution of energy to the brittle particles is thus made indirectly available to the layer structure with the ductile particles.
  • the particles of the second type are produced from a metal or a metal alloy which is ductile above a transition temperature and below this temperature brittle, the particles of the second type in the stagnation chamber are heated far, that they behave ductile. If it is possible to bring about by preheating the particles of the second type, that these are also ductile, so deposition of these particles is advantageously possible, without these having to be incorporated in a matrix of walls ⁇ ren material. This results in advantageous that the proportion of the brittle material itself can be arbitrarily increased, as a matrix enclosing these particles of the other layer component not more is necessary. This advantageously leads to the fact that with the cold gas spraying a larger range of alloy compositions can be deposited.

Abstract

L'invention concerne un procédé de projection dynamique par gaz froid de particules de différente dureté et/ou ductilité, ainsi qu'un dispositif (1) de projection dynamique par gaz froid adapté audit procédé. L'invention vise à obtenir une teneur relativement élevée en particules (23) présentant une dureté accrue et/ou une ductilité réduite par rapport à d'autres particules (22). A cet effet, les particules sont introduites dans une zone (21) de la chambre de stagnation (15) du dispositif de projection dynamique par gaz froid, cette zone étant éloignée de la tuyère (14). Par conséquent, les particules (23) doivent avantageusement parcourir une plus grande distance à travers la chambre de stagnation et sont ainsi préchauffées. Il est alors possible d'améliorer la séparation de ces particules (23) sur un substrat (25). Le préchauffage permet de conférer des propriétés ductiles en particulier à des métaux dont la température de transition oscille entre un comportement cassant et ductile, ce qui facilite leur séparation.
