    Sammanfattning : Some of the biggest problems currently facing the world are closely tied to unsolved technological challenges in the material sciences. Many materials have a porous microstructure that controls their overall properties. LÄS MER

  2. 2. Porous degradable polyester scaffolds

    Detta är en avhandling från Stockholm : KTH

    Författare :Peter Plikk; KTH.; [2006]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; aliphatic polyester; copolymer; porous scaffold; ring-opening polymerization; electron beam; gamma irradiation; Polymerteknologi; NATURAL SCIENCES Chemistry; NATURVETENSKAP Kemi;

    Sammanfattning : Tissue engineering is a growing research field in which degradable porous scaffolds are used to regenerate tissue from the patients own cells. The problems due to donor shortage or the lack of full property restoration from prosthetic implants can thereby be overcome. LÄS MER

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

    Detta är en avhandling från Trollhättan : University West

    Författare :Ashish Ganvir; Högskolan Väst.; [2016]
    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;

    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

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

    Detta är en avhandling från Trollhättan : University West

    Författare :Peter Harlin; [2008]
    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
