  1. 36. Microstructure and Thermal Conductivity of Liquid Feedstock Plasma Sprayed Thermal Barrier Coatings

    Författare :Ashish Ganvir; Nicolaie Markocsan; Per Nylén; Ru Lin Peng; Högskolan Väst; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Microstructure; Thermal Barrier Coating; Axial Injection; Suspension Plasma Spraying; Suspension High Velocity Oxy Fuel Spraying; Solution Precursor Plasma Spraying; Porosity; Thermal Diffusivity; Thermal Conductivity; Production Technology; Produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik;

    Sammanfattning : Thermal barrier coating (TBC) systems are widely used on gas turbine components to provide thermal insulation and oxidation protection. TBCs, incombination with advanced cooling, can enable the gas turbine to operate at significantly higher temperatures even above the melting temperature of the metallic materials. LÄS MER

    Sammanfattning : Titanium alloys are widely used for components in the fan and compressor sections of aeroengines mainly because of their superior strength-to-weight ratio. Large static compressor components can be manufactured by welding together smaller subcomponents, which has potential to provide benefits such as higher buy-to-fly ratio and improved performance of the components.

  5. 39. On the processing of starch consolidated high speed steel - Microstructure and tribological properties

    Författare :Peter Harlin; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tribological properties; green body; microstructure; porosity; high speed steel; Starch consolidation; super solidus liquid phase sintering; mechanical properties;

    Sammanfattning : This thesis focuses on processing of high speed steel (HSS) powder into components using starch consolidation (SC) and supersolidus liquid phase sintering (SLPS). The work consists of four parts. First, the possibilities and constrains of the SC process are investigated and the role of starch in the green body fabrication clarified. LÄS MER
