  1. 1. Light scattering for analysis of thermal stress induced deformation in thin metal films

    Detta är en avhandling från Stockholm : Fysik

    Författare :Carina Kylner; KTH.; [1997]
    Nyckelord :thin metal films; aluminum; optical quality; hillock; initial stage; lateral distribution; thermal stress; light scattering; instrument.;

    Sammanfattning : Today, thin film based devices are found in a wide field of applications. The main reasons are that thin film technology enables access to unique physical properties and possibilities to miniaturize devices. Thin film devices are generally described in terms such as electrical, optical and magnetical properties. LÄS MER

  2. 2. 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

  3. 3. Integration and Packaging Concepts for Infrared Bolometer Arrays 

    Detta är en avhandling från Stockholm : KTH

    Författare :Adit Decharat; KTH.; [2009]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fabrication; Bonding; packaging; microbolometer; Thermal imaging.; TECHNOLOGY Electrical engineering; electronics and photonics Other electrical engineering; electronics and photonics; TEKNIKVETENSKAP Elektroteknik; elektronik och fotonik Övrig elektroteknik; elektronik och fotonik;

    Sammanfattning :  Infrared (IR) imaging devices based on energy detection has shown a dramatic development in technology along with an impressive price reduction in recent years. However, for a low-end market as in automotive applications, the present cost of IR cameras is still the main obstacle to broadening their usage. LÄS MER

  4. 4. Multiscale materials design of hard coatings for improved fracture resistance and thermal stability

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Phani Kumar Yalamanchili; Linköpings universitet.; Linköpings universitet.; [2016]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Physical vapor deposited hard coatings comprised of cubic (c) transition metal (TM)-Al-N, and (TM)-Si-N are the current workhorse materials for a large number of metal cutting and wear resistant applications to fight against the extreme conditions of temperature and stress simultaneously. In spite of a high degree of sophistication in terms of material choice and microstructural design, a lower fracture resistance and limited thermal stability of the coatings remains a technological challenge in the field.

  5. 5. Thermal Capacity of Railway Wheels - Temperatures, residual stresses and fatigue damage with special focus on metro applications

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Shahab Teimourimanesh; [2014]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; railway tread braking; finite element analysis; frictional heating; fatigue damage; metro trains; rig field experiments; railway wheels; stop braking; temperatures;

    Sammanfattning : Tread (block) braking is still one of the most common braking systems on railway vehicles.The action is carried out by pressing brake blocks against the tread of a wheel, which is also inrolling contact with the rail. LÄS MER
