Effect of Nb Addition on Oxidation Mechanisms of High Cr Ferritic Steel in Ar–H2–H2O

Autor: W. J. Quadakkers, Ivan Povstugar, Dmitry Naumenko, Timur Galiullin, Ashok Vayyala, Joachim Mayer, H. Hattendorf

Publikováno v: Oxidation of Metals. 92:471-491

High chromium ferritic steels are being used as construction materials for interconnects in solid oxide electrolysis cells (SOEC). Addition of niobium in the range of a few tenths of a percent is suitable for increasing the high-temperature creep str

Effect of Zr Content on the Morphology and Emissivity of Surface Oxide Scales on FeCrAlY Alloys

Autor: Sayee Ganesh Gopalakrishnan, H. Hattendorf, Riza Iskandar, Joachim Mayer, P. Huczkowski, Willem J. Quadakkers, Wojciech J. Nowak

Publikováno v: Advanced Engineering Materials. 18:711-720

The investigation aims at obtaining a life time extension of FeCrAlY heating elements by increasing the emissivity of the alumina surface scales. This approach will allow the use of a lower heating element temperature without decreasing the usable he

Temperature Dependence of Laves Phase Composition in Nb, W and Si-Alloyed High Chromium Ferritic Steels for SOFC Interconnect Applications

Autor: Uwe Breuer, W. J. Quadakkers, Leszek Niewolak, A. Savenko, H. Hattendorf, Daniel Grüner

Publikováno v: Journal of Phase Equilibria and Diffusion. 36:471-484

The Laves phase strengthened ferritic steel Crofer 22 H has been proposed as construction material for interconnects in solid oxide fuel cells. The background of the present study relates to the further qualification of this steel, especially with re

Modeling carbide dissolution in alloy 602 CA during high temperature oxidation

Autor: Rishi Pillai, H. Hattendorf, A. Chyrkin, Silvia Richter, H. Ackermann, Daniel Grüner, Willem J. Quadakkers, Wojciech J. Nowak

Publikováno v: Corrosion Science. 96:32-41

The high-temperature oxidation resistance of the carbide strengthened nickel-base alloy 602 CA is provided by the formation of a protective outer Cr 2 O 3 scale accompanied by internal precipitation of alumina and dissolution of Cr-rich carbides. The

On the physical nature of tribolayers and wear debris after sliding wear in a superalloy/steel tribosystem at 25 and 300°C

Autor: C. Rynio, H. Hattendorf, J. Klöwer, Gunther Eggeler

Publikováno v: Wear. 317:26-38

Dry sliding wear of metals is strongly affected by the formation of oxide particles and their incorporation into compacted oxide layers, so-called glaze layers. A high-temperature reciprocating pin-on-disc tribometer was used to study the tribologica
