  2. 21. Functional Performance of Gadolinium Zirconate/Yttria Stabilized Zirconia Multi-Layered Thermal Barrier Coatings

    Author : Satyapal Mahade; Per Nylén; Nicolaie Markocsan; Högskolan Väst; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Erosion; Gadolinium Zirconate; Suspension Plasma Spray; Thermal Barrier Coatings; Thermal Cyclic Test; Thermal Conductivity; Yttria Stabilized Zirconia; Production Technology; Produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik;

    Abstract : Yttria stabilized zirconia (YSZ) is the state of the art ceramic top coat material used for TBC applications. The desire to achieve a higher engine efficiency of agas turbine engine by increasing the turbine inlet temperature has pushed YSZ toits upper limit. READ MORE

  5. 23. Nanocrystalline Alumina-Zirconia Thin Films Grown by Magnetron Sputtering

    Author : David Huy Trinh; Hans Högberg; Marianne Collin; Lars Hultman; Ingrid Reineck; Mats Halvarsson; Linköpings universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : Alumina-zirconia thin films have been deposited using dual magnetron sputtering. Film growth was performed at relatively low-to-medium temperatures, ranging from ~300°C to 810 °C. Different substrates were applied, including silicon (100), and industrially relevant materials, such as WC-Co hardmetal. READ MORE

  6. 24. RhPt and Ni based catalysts for fuel reforming in energy conversion

    Author : Angélica Viviana González Arcos; Lars J. Pettersson; Klas Engvall; Anker Jensen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; RhPt bimetallic catalysts; Ni catalysts; ceria-zirconia; potassium tungsten bronze; zirconium dioxide; autothermal reforming; biodiesel; diesel; sulfur; deactivation; tar reforming; steam reforming; biomass gasification; auxiliary power units; naphthalene; Chemical Engineering; Kemiteknik;

    Abstract : Although current trends in global warming are of great concern, energy demand is still increasing, resulting in increasing pollutant emissions. To address this issue, we need reliable renewable energy sources, lowered pollutant emissions, and efficient and profitable processes for energy conversion. READ MORE

  7. 25. Functional Performance of Gadolinium Zirconate/Yttria Stabilized Zirconia Multi-Layered Thermal Barrier Coatings

    Author : Satyapal Mahade; Per Nylén; Nicolaie Markocsan; Ping Xiao; Högskolan Väst; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Composite; Erosion; Gadolinium Zirconate; Suspension Plasma Spray; Thermal Barrier Coatings; Thermal Cyclic Test; Thermal Conductivity; Yttria Stabilized Zirconia.; Production Technology; Produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik;

    Abstract : Yttria stabilized zirconia (YSZ) is the state-of-the-art ceramic top coat material used for thermal barrier coating (TBC) applications. Demand for higher efficiency in gas turbine engines has led to a continuous increase in the gas in let temperature. However, this increase in temperature has pushed YSZ to its upper limit. READ MORE
