  1. 6. Adhesion and Residual Stress Characterization of HVOF Sprayed Inconel 718 Coatings

    Författare :Christophe Lyphout; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HVOF; Residual Stress; Inconel 718; Thermal spray; Adhesion Strength; Finite Element Method; High Velocity Oxy-Fuel;

    Sammanfattning : Thermal spray technology in general is nowadays recognized as an industrial process, mature enough to apply coatings on different substrate materials that protect parts against wear, corrosion, heat, or combinations of these. The quality demands on coating homogeneity and adhesion strength are, nowhere more than in the automotive and aeronautic industries, continuously increasing. LÄS MER

  5. 9. Static and fatigue analyses of welded steel structures : some aspects towards lightweight design

    Författare :Mansoor Khurshid; Zuheir Barsoum; Lars-Erik Lindgren; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fatigue strength; welded joints; static strength; high strength steel; Farkostteknik; Vehicle and Maritime Engineering; Aerospace Engineering; Flyg- och rymdteknik;

    Sammanfattning : The objectives of this thesis comprise of overcoming the challenges in designing lightweight welded structures such as material selection, choice of fatigue design methods, and increased performance by using improvement techniques. Material selection of welded joints is dependent on the filler and base material strengths. LÄS MER

  7. 10. Some factors affecting the amount of residual phase lignin during kraft pulping

    Författare :Mikael E. Lindström; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Deligniflcation; Residual phase lignin; Hydrogensulfide ion; Hydroxide ion; Polysulfides; Ionic strength; Temperature; Lignin; Kraftpulping; Selectivity; viscosity; Kappa number; chemical degradation; Disproportionation; Cellulose and paper engineering; Cellulosa- och pappersteknik;

    Sammanfattning : The amount of lignin which needs to be removed according to the slow residual delignification phase in kraft pulping, i e residual phase lignin, has been studied as a function of the process conditions. The variebles studied were the concentrations of hydroxide ions, hydrogensulfide ions, sodium ions (ionic strength) and temperature. LÄS MER
