  1. 1. Corrosion Resistant Multi-Component Coatings for Hydrogen Fuel Cells

    University essay from Linköpings universitet/Tunnfilmsfysik

    Author : Jakob Steneteg; [2021]
    Keywords : Coatings; Hydrogen Fuel Cells; Multi-Component; High Entropy Alloys; Corrosion Resistance;

    Abstract : Multi-component coatings and high entropy alloys have in recent years attracted great interest for research, since they have shown to exhibit properties greater than the com- ponents of their parts. Today’s climate challenges requires transitioning from fossil fuels to renewable energy sources which demands use of new technology and new innovations. READ MORE

  3. 2. Ferroelectricity in nanocrystalline Hf0.5Zr0.5O2 thin films

    University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Author : Lun Sang; [2018]
    Keywords : ferroelectricity; Hf0.5Zr0.5O2; GIXRD; XRR; Technology and Engineering; Physics and Astronomy;

    Abstract : Hafnium dioxide (HfO_2) based thin films doped with various dopants (Si, Ge, Al, Gd, Sr, Zr) have been found to exhibit ferroelectricity. These dopants were found to stabilize the III orthorhombic phase in the hafnium oxide based thin films. READ MORE

  4. 3. Optimizing Transmission Kikuchi Diffraction for Analysing Grain Size and Orientation of Nanocrystalline Coatings

    University essay from Uppsala universitet/Tillämpad materialvetenskap

    Author : Axel Tryblom; [2015]
    Keywords : TKD; t-EBSD; Kikuchi diffraction; coating; nanocrystalline; sample preparation; in situ lift-out; DualBeam; precision mechanical polishing; SEM;

    Abstract : In order to increase efficiency and lifetime of cutting tools it is typical to apply thin coatings by physical or chemical vapour deposition. Applying coatings on cutting tools has shown an increase in both efficiency and lifetime and are of large interest in further development. READ MORE

  5. 4. Magnetism of Nanocrystallized Amorphous Fe75B10Si15

    University essay from KTH/Materialvetenskap

    Author : Arnab Chakraborty; [2012]
    Keywords : amorphous metals; nanocrystalline materials; magnetism; soft magnetic material;

    Abstract : Amorphous ribbons of alloy composition Fe75B10Si15 are cast by melt spinning and annealed to partially nanocrystalline states. The magnetic properties are investigated by VSM and MTGA. Structure is examined using XRD and SEM. READ MORE
