  1. 1. Aspects of fatigue life in thermal barrier coatings

    Detta är en avhandling från Linköping : Linköpings universitet

    Författare :Håkan Brodin; Linköpings universitet.; Linköpings universitet.; [2001]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Thermal barrier coatings (TBC) are applied on hot components in airborne and land-based gas turbines when higher turbine inlet temperature, meaning better thermal efficiency, is desired. The TBC is mainly applied to protect underlying material from high temperatures, but also serves as a protection from the aggressive corrosive environment. LÄS MER

  2. 2. Failure of thermal barrier coatings under thermal and mechanical fatigue loading : microstructural observations and modelling aspects

    Detta är en avhandling från Linköping : Linköpings universitet

    Författare :Håkan Brodin; Linköpings universitet.; Linköpings universitet.; [2004]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermal barrier coating; TBC; delamination; crack initiation; crack propagation; crack growth; oxidation; alumina; spinel; MCrAIY; diffusion; fatigue; modelling; modeling; degradation; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Industrial and air-borne gas turbine hot components suffer from creep, oxidation, corrosion and microstructural degradation if not shielded from the hot and aggressive combustion gases. Two major strategies commercially available are adopted; film cooling by pressurised air and application of protective coatings. LÄS MER

  3. 3. Regional variations in pharmaceutical consumption in Sweden

    Detta är en avhandling från Linköping : Linköpings universitet

    Författare :Håkan Brodin; Linköpings universitet.; Linköpings universitet.; [1987]
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; regional variations; health care utilization; pharmaceuticals; health economics; population-based; multiple regression analysis; lisrel analysis; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Sammanfattning : Secondary, non-sample data, mainly from official statistics from 259 municipalities in Sweden, are used to investigate systematic variations in the consumptian of pharmaceuticals on the county and municipality level. The theoretical framework is taken from health economics. LÄS MER
