Title (EN) IMPROVED COATING BLADE
(FR) LAME ENDUITE AMÉLIORÉE
Abstract:
(EN) Improved coating blades are disclosed, as well as processes for manufacturing such blades. The inventive blades have an intermediate edge deposit (3) effective to reduce heat transfer from a wear resistant top deposit (2) to the blade substrate (1) . In one embodiment, the intermediate layer is comprised of NiCr, possibly with embedded oxide particles. Suitably, the intermediate layer and the top deposit are applied by an HVOF process. It is also envisaged that the intermediate layer may be deposited by plasma spraying. The intermediate layer may comprise stabilized zirconia.
(FR) La présente invention concerne des lames enduites améliorées, ainsi que des procédés pour fabriquer de telles lames. Les lames de l’invention ont un dépôt intermédiaire sur les bords (3) efficace pour réduire le transfert thermique du dépôt supérieur résistant à l’usure (2) au substrat de la lame (1). Dans un mode de réalisation, la couche intermédiaire est composée de NiCr, probablement avec des particules d’oxyde incrustées. De manière appropriée, la couche intermédiaire et le dépôt supérieur sont appliqués au moyen d’un procédé HVOF. Il est également envisagé que la couche intermédiaire puisse être déposée par pulvérisation au plasma. La couche intermédiaire peut comprendre de la zircone stabilisée.
