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.
