  1. 16. Microstructural, Residual Stress, and Thermal Shock Studies of Plasma Sprayed ZrO2-Based Thermal Barrier Coatings

    Författare :Per Bengtsson; R. Taylor; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Thermal barrier coatings (TBCs), with a thickness of 0.4 mm, are today extensively used on the hot parts of both stationary and flying jet engines. The purpose of the TBC is to protect the underlying material from high temperatures and severe thennal shock. LÄS MER

  3. 17. Optimisation of Off-Road Transport Missions

    Författare :Jörgen Albrektsson; Jan Åslund; Lars Eriksson; Nikolce Murgovski; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Mines, construction sites, road construction and quarries are examples of applications where construction equipment are used. In a production chain consisting of several construction machines working together, the work needs to be optimised and coordinated to achieve an environmental friendly, energy efficient and productive production.

  4. 18. Hot-wall MOCVD of N-polar group-III nitride materials and high electron mobility transistor structures

    Författare :Hengfang Zhang; Vanya Darakchieva; Jr-Tai Chen; Ingemar Persson; Fatemeh (Shadi) Shahedipour-Sandvik; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nitrogen-polar; MOCVD; III-nitride; GaN; AlN; C-face SiC; HEMTs;

    Sammanfattning : Group III-Nitride semiconductors: indium nitride (InN), gallium nitride (GaN), aluminum nitride (AlN) and their alloys continue to attract significant scientific interest due to their unique properties and diverse applications in photonic and electronic applications. Group-III nitrides have direct bandgaps which cover the entire spectral range from the infrared (InN) to the ultraviolet (GaN) and to the deep ultraviolet (AlN). LÄS MER
