  5. 4. Atom Probe Tomography of Hard Nitride and Boride Thin Films

    Författare :David L. J. Engberg; Lars Hultman; Magnus Odén; Guido Schmitz; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Atom probe tomography APT ; Ceramics; Nitrides; Borides;

    Sammanfattning : Hard ceramic thin films, including TiSiN, ZrAlN, ZrB2, and ZrTaB2, with applications for wear-resistant coatings, have been studied using atom probe tomography and correlated with several other analytical techniques, including X-ray diffraction, electron microscopy, and elastic recoil detection analysis. Outstanding obstacles for quantitative atom probe tomography of ceramic thin films have been surmounted. LÄS MER

  7. 5. Atom probe tomography of Zircaloy-2 exposed to boiling water reactor operation
