  1. 1. Atom Probe Tomography of TiSiN Thin Films

    Författare :David Engberg; Lars Hultman; Magnus Odén; Fang Liu; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis concerns the wear resistant coating TiSiN and the development of the analysis technique atom probe tomography (APT) applied to this materials system. The technique delivers compositional information through time-of-flight mass spectrometry, with sub-nanometer precision in 3D for a small volume of the sample. LÄS MER

  3. 2. Oxidation behaviour of MCrAlX coatings : effect of surface treatment and an Al-activity based life criterion

    Författare :Pimin Zhang; Ru Lin Peng; Xin-Hai Li; Sten Johansson; Fang Liu; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : MCrAlY coatings (M=Ni and/or Co) have been widely used for the protection of superalloy components against oxidation and hot corrosion in the hot sections of gas turbines. The drive to improve engine combustion efficiency while reducing emissions by increasing the operation temperature brings a big challenge for coating design. LÄS MER

  7. 5. State Estimation of Lithium-ion Batteries

    Författare :Xiaolei Bian; Longcheng Liu; Jinying Yan; Huazhen Fang; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lithium-ion battery; State of charge; State of health; Model-based method; Extended Kalman filter; Filter tuning; Fusion model; Chemical Engineering; Kemiteknik;

    Sammanfattning : To guarantee the safety operation, the key states of lithium-ion battery, e.g., the state of charge and the state of health, must be estimated and monitored accurately. This thesis is mainly to develop models and algorithms to accurately and robustly estimate the key battery states, based on the available measurements i. LÄS MER
