  4. 4. Cr Vaporization and Oxide Scale Growth on Interconnects in Solid Oxide Fuel Cells

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Hannes Falk Windisch; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Corrosion; Interconnect; Cr Vaporization; SOFC; Coatings;

    Abstract : The vaporization of Cr(VI) species and the greater electrical resistance caused by a growing oxide scale are probably the two most detrimental degradation mechanisms associated with the use of Cr2O3-forming alloys as the interconnect material in a Solid Oxide Fuel Cell (SOFC). High electrical efficiency, clean emissions and the possibility to utilize several types of fuels, such as hydrogen, alcohols and hydrocarbons are some of the great advantages of SOFC technology.

  5. 5. Grinding effects on surface integrity, flexural strength and contact damage resistance of coated hardmetals

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Jing Yang; Linköpings universitet.; Linköpings universitet.; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The tribological and mechanical behavior of coated tools depends not only on intrinsic properties of the deposited film but also on substrate surface and subsurface properties – such as topography and residual stress state – as well as on interface adhesion strength. It is particularly true in the case of coated tools based on WC-Co cemented carbides (backbone materials of the tool manufacturing industry, and simply referred to as hardmetals in practice) as substrates.
