Description
La présente invention concerne un procédé de revêtement d'une encoche en forme de Z inversé de pièces en alliage de Nickel ayant une paroi plane précédée d'un arrondi. Ces pièces sont notamment des ailettes de turbine à gaz en alliage de Nickel difficilement soudables.The present invention relates to a method of coating an inverted Z-shaped notch of nickel alloy parts having a flat wall preceded by a rounded one. These parts are in particular fins of gas turbine made of nickel alloy which are difficult to weld.
Les procédés TIG manuel et mini-plasma sont beaucoup plus longs à employer et dépendent trop de l'opérateur.Manual TIG and mini-plasma processes take much longer to use and depend too much on the operator.
On pourrait penser à utiliser un procédé laser à puissance très élévée pour permettre un bon ancrage des couches dans le fond de l'encoche mais les essais effectués ont montré qu'on ne pourrait pas tenir les prescriptions de la spécification concernant les fissurations.One could think of using a laser method with very high power to allow a good anchoring of the layers in the bottom of the notch but the tests carried out showed that one could not hold the prescriptions of the specification concerning the cracks.
Le procédé selon l'invention permettant d'obtenir un revêtement métallique anti-usure sans fissuration ayant une bonne liaison métallique avec le substrat dans les zones de contact de formes complexes est caractérisé en ce qu'on utilise un faisceau laser orientable et déplaçable relativement par rapport à la paroi plane de l'encoche et faisant un angle fixe α₂ par rapport à un faisceau de poudre, le faisceau laser faisant un angle α par rapport à la normale N à la paroi plane de l'encoche et, la direction du faisceau de poudre un angle α + α₂ avec ladite normale N, en ce que lors de l'élaboration des diverses couches on réalise plusieurs passes longitudinales à vitesse constante partant du fond de l'encoche vers le bord, le point de rencontre 0 entre faisceau laser et la direction de projection de la poudre restant immobile quelques dizièmes de secondes sur l'arrondi de l'encoche au début de chaque passe longitudinale et en ce que lors de l'élaboration de la première couche l'aryle α reste constant et égal à un angle α₁ inférieur à 30° tandis que lors de l'élaboration des couches suivantes l'angle α au début de chaque prend d'abord une valeur supérieure à α₁ qui peut être aussi proche que possible de la normale à l'arrondi, puis le faisceau laser et le faisceau de poudre tournent autour du point de rencontre 0 qui reste immobile jusqu'à ce que le faisceau laser prenne l'angle 1 avant de commencer à se déplacer pour réaliser ladite passe.The method according to the invention making it possible to obtain a non-cracking anti-wear metallic coating having a good metallic bond with the substrate in the contact areas of complex shapes is characterized in that a laser beam is orientable and relatively displaceable by relative to the plane wall of the notch and making a fixed angle α₂ with respect to a powder beam, the laser beam making an angle α with respect to the normal N to the plane wall of the notch and, the direction of the beam powder an angle α + α₂ with said normal N, in that during the preparation of the various layers, several longitudinal passes are made at constant speed starting from the bottom of the notch towards the edge, the meeting point 0 between the laser beam and the direction of projection of the powder remaining stationary for a few tenths of a second on the rounding of the notch at the start of each longitudinal pass and in that during the preparation of the first layer the aryl α remains constant and equal to an angle α₁ less than 30 ° while during the preparation of the following layers the angle α at the start of each first takes a value greater than α₁ which can be as close as possible to the normal to rounding, then the laser beam and the powder beam rotate around the meeting point 0 which remains stationary until the laser beam takes the
De préférence, le point de contact 0 au début des passes est positionné dans l'arrondi à l'intérieur du matériau.Preferably, the contact point 0 at the start of the passes is positioned in the rounding inside the material.
L'invention va maintenant être décrite plus en détail en se référant à un mode de réalisation particulier cité à titre d'exemple non limitatif et représenté par des dessins annexés.The invention will now be described in more detail with reference to a particular embodiment cited by way of nonlimiting example and shown in the accompanying drawings.

La figure 6 représente le dépôt de la couche des figures 4 et 5 sur la face plane de l'encoche.Figure 6 shows the deposition of the layer of Figures 4 and 5 on the flat face of the notch.
La figure 7 représente la coupe de la figure 1.FIG. 7 represents the section of FIG. 1.
Le profil brut 1 de l'aube en alliage de nickel est représenté en pointillé sur la figure 1. Ce profil est en forme de "Z inversé" et comporte dans la partie intermédiaire du "Z inversé" une encoche 2 constituée d'une partie arrondie 3 suivie d'une partie plane 4 correspondant à la partie intermédiaire du "Z inversé".The
On revêt l'encoche 2 de plusieurs couches 5, 5', planes parallèles à la partie plane 4 à l'aide d'un laser CO₂ dans le faisceau duquel on projette une poudre métallique.The notch 2 is coated with
Chaque couche 5 est constituée de plusieurs cordons 6 adjacents déposés au cours de passes successives (voir figure 7).Each
Le dépôt est constitué d'un revêtement métallique anti-usure sans fissuration ayant une bonne liaison métallique avec le substrat en alliage de Nickel.The deposit consists of a non-cracking anti-wear metallic coating having a good metallic bond with the Nickel alloy substrate.
L'ensemble du "Z" est réusiné pour obtenir le profil final 7 en trait plein sur la figure 1.The entire "Z" is remanufactured to obtain the
Le faisceau laser 8 est orientable et déplaçable par rapport à la paroi plane 4 de l'encoche 2. La direction du faisceau laser et la direction 9 de projection de la poudre font un angle constant α₂ (voir figure 2).The laser beam 8 is orientable and movable relative to the planar wall 4 of the notch 2. The direction of the laser beam and the
Etant donné la forme complexe de la pièce et le confinement de la zone à traiter on incline le faisceau laser 8 par rapport à la normale N à la paroi plane 4 de l'encoche 2 d'un angle α de quelques dizaines de degré. Cet angle dépend du profil d'aube.Given the complex shape of the part and the confinement of the area to be treated, the laser beam 8 is inclined relative to the normal N to the plane wall 4 of the notch 2 at an angle α of a few tens of degrees. This angle depends on the blade profile.
On le choisit pour qu'il soit aussi petit que possible c'est-à-dire pratiquement pour que le faisceau 8 soit confondu ou voisin de la parallèle au plan de la première branche 10 du "Z inversé".It is chosen so that it is as small as possible, that is to say practically so that the beam 8 is coincident or close to the parallel to the plane of the
Ainsi le faisceau 8 fait-il un angle α avec la normale N et la direction 9 de projection de la poudre un angle α + α₂.Thus the beam 8 makes an angle α with the normal N and the
Réalisation de la première couche (voir figures 2 et 3). L'angle d'inclinaison du faisceau laser 8 est fixé à α₁ et il ne sera pas modifié pendant toute la réalisation de la première couche 5; dans l'exemple précis α₁ a été pris égal à 25° et est sensiblement parallèle à la première branche 10 du "Z inversé".Creation of the first layer (see Figures 2 and 3). The angle of inclination of the laser beam 8 is fixed at α₁ and it will not be modified during the entire production of the
Sur le fond arrondi 3 de l'encoche 2, on positionne le point d'intersection 0 entre le faisceau laser 8 et le faisceau poudre 9 à l'intérieur du matériau (quelques dizièmes de mm), ce qui permet d'une part de rattraper l'écart d'altitude avec la partie plane 4 de la zone à revêtir et d'éviter ainsi toute modification ultérieure de son positionnement lors de la réalisation de la passe en cours et d'autre part de maintenir le faisceau poudre 9 en aval du point de contact faisceau laser/pièce afin d'assurer une meilleure fusion de la poudre et minimiser les projections de particules vers le fond d'encoche 2 (figure 2).On the
Le point d'intersection 0 est par ailleurs, maintenu quelques dizièmes de seconde à l'intérieur du matériau sans déplacement afin d'augmenter le temps d'intéraction laser/matière et assurer une fusion du substrat.
L'ensemble faisceau laser 8/faisceau poudre 9 (angle α 2 contant) est ensuite déplacé à vitesse constante jusqu'au bord 11 du "Z inversé", le point d'intersection faisceau/poudre se trouvant à la surface du substrat (figure 3).The point of intersection 0 is also maintained for a few tenths of a second inside the material without displacement in order to increase the laser / material interaction time and ensure a substrate melting.
The laser beam 8 /
On recommence l'opération jusqu'à ce que la première couche 5 soit déposée.The operation is repeated until the
Réalisations des couches ultérieures (figure 4 à 6). Pour attaquer la nouvelle couche 5' (la cinquième sur la figure 4), le faisceau laser 8 est incliné par rapport à la normale N d'un angle α₃ qui se rapproche le plus possible de la normale N à l'arrondi 3, ce qui permet une meilleure absorption du faisceau laser 8 pour la matière : il faut évidemment que le faisceau de poudre 9 (incliné de α₂ avec α₂ constant et 10° ≦ α₂≦ 20°) soit au-dessus de la paroi plane 4, ce qui empêche d'avoir un angle α₃ trop important.Realizations of subsequent layers (Figure 4 to 6). To attack the
L'angle α₃ est donc variable de couche à couche.The angle α₃ is therefore variable from layer to layer.
Comme pour la première couche 5 le point d'intersection 0 faisceau/poudre se trouve à l'intérieur du matériau de l'arrondi. Une rotation de l'ensemble faisceaux laser, poudre 8, 9 est alors effectuée en ce point en quelques dizièmes de seconde (<1 s) afin d'augmenter le temps d'intéraction et de replacer le faisceau laser 8 en position pour construire la nouvelle passe.As for the
Le faisceau laser 8 fait alors l'angle α₁ avec le normale N et il est déplacé comme lors du dépôt de la première couche 5 avec α₁ et α₂ constants du fond 3 de l'encoche 2 vers le bord 11 en restant en surface de la couche déposée antérieurement (voir figure 6). Pour chaque passe on repart du fond 3 avec un faisceau laser 8 faisant un angle α₃ (le même pour une couche déterminée) avant de redresser le faisceau 8 qui fait un angle α₁ puis à le déplacer vers le bord avec le faisceau laser 8 restant incliné avec α₁ constant.The laser beam 8 then makes the angle α₁ with the normal N and it is displaced as during the deposition of the
