(EN) COMPONENT CONSISTING OF AN UNALLOYED OR LOW-ALLOY STEEL, METHOD FOR PROTECTING SAID COMPONENTS AGAINST COKE DEPOSITION OR METAL DUSTING
(FR) PIÈCE CONSTITUÉE D'ACIER NON ALLIÉ OU FAIBLEMENT ALLIÉ, PROCÉDÉ POUR PROTÉGER CES PIÈCES CONTRE UN DÉPÔT DE COKE OU UNE FORMATION DE POUSSIÈRE MÉTALLIQUE
Abstract
(DE) Die Erfindung sieht zur Erhöhung der Beständigkeit von un- und niedriglegierten Stählen unter Metal Dusting Bedingungen das Aufbringen einer intermetallischen Me-Sn-Phase vor. Es hat sich gezeigt, dass eine solche intermetallische Me-Sn-Phase (Me = Fe,Ni,Co) auf niedriglegierten Stählen deren Beständigkeit unter Metal Dusting Atmosphären bei hohen Temperaturen erheblich erhöht. Die intermetallische Me-Sn-Phase kann mit unterschiedlichen Verfahren appliziert werden, z. B. Packdiffusion, elektrochemische Co-Abscheidung, als Anstrich oder über Sputtern mit anschließender thermischer Behandlung. Die Fe-Sn- bzw. Co-Sn-Phase kann nicht direkt appliziert werden, da Zinn nicht in Eisen, Kobalt oder Ferriten diffundiert. Hierbei dient eine Nickelschicht als Mediator.
(EN) The invention relates to applying an intermetallic Me-Sn phase for increasing the durability of unalloyed and low-alloy steels under conditions of metal dusting. It has been demonstrated that such an intermetallic Me-Sn phase (ME = Fe,Ni,Co) on low-alloy steels significantly increases the durability thereof under metal dusting atmospheres at high temperatures. The intermetallic Me-Sn phase can be applied by means of various methods, such as pack diffusion, electrochemical CO deposition, as a paint, or by sputtering with subsequent thermal treatment. The Fe-Sn- or Co-Sn phase can not be applied directly, because tin does not diffuse in iron, cobalt, or ferrites. A nickel layer acts as a mediator.
(FR) L'invention vise à déposer une phase Me-Sn intermétallique pour augmenter la résistance d'aciers non alliés ou faiblement alliés, dans des conditions de formation de poussière métallique. Il a été démontré qu'une telle phase Me-Sn intermétallique (Me = Fe,Ni,Co) appliquée sur des aciers faiblement alliés augmente considérablement leur résistance dans des conditions de formation de poussière métallique, à hautes températures. La phase Me-Sn intermétallique peut s'appliquer par différents procédés, par exemple, par diffusion "pack", par dépôt électrochimique de coke, en tant qu'enduction ou par pulvérisation, suivie d'un traitement thermique subséquent. La phase Fe-Sn ou Co-Sn ne peut pas être appliquée directement, car l'étain ne diffuse pas dans le fer, le cuivre ou les ferrites. La couche de nickel sert ici de médiateur.
