(FR) COUCHE DE LIAISON MCRALY ET SON PROCEDE DE DEPOT
Abstract: front page image
(EN)A method of depositing a bond coating to a surface of an article (1) comprising the steps of depositing an inner layer (2) of the bond coating consisting of beta-NiAl comprising Fe, Ga, Mo, B, Hf or Zr or gamma/beta-MCrAlY comprising Fe, Ga, Mo, B, Hf or Zr or gamma/gamma prime - or gamma-MCrAlY, and depositing an outer layer (3) of the bond coating, which is more coarse the in the inner layer (2), consisting of beta-NiAl comprising Fe, Ga, Mo, B, Hf or Zr or gamma/beta-MCrAlY comprising Fe, Ga, Mo, B, Hf or Zr or gamma/ gamma prime - or gamma-MCrAlY, wherein said elements Fe, Ga, Mo, B, Hf or Zr above mentioned are present individually or in combination. The coating comprises a platinum type metal selected from the group consisting of platinum, palladium and rhodium in the coating or as a different layer (5).
(FR)L'invention concerne un procédé de dépôt d'une couche de liaison sur une surface d'un article (1) consistant à déposer une couche interne (2) de la couche de liaison constituée de bêta-NiAl comprenant Fe, Ga, Mo, B, Hf ou Zr ou gamma/bêta-MCrALY comprenant Fe, Ga, Mo, B, Hf ou Zr ou gamma/gamma amorce ou gamma-MCrALY et à déposer une couche externe (3) de la couche de liaison, plus grossière que la couche interne (2), constituée de bêta-NiAl comprenant Fe, Ga, Mo, B, Hf ou Zr ou gamma/bêta-MCrALY comprenant Fe, Ga, Mo, B, Hf ou Zr ou gamma/gamma amorce ou gamma-MCrALY, lesdits éléments Fe, Ga, Mo, B, Hf ou Zr précités sont présents individuellement ou de manière combinée. La couche comprend un métal de type platine sélectionné dans le groupe constitué de platine, palladium et rhodium dans la couche ou comme couche différente (5).
