  2. 1. Growth and Nano-structural Studies of Metallic Multilayer for X-ray Mirrors

    Author : Naureen Ghafoor; Jens Birch; Gabriella Andesson; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soft X-rays; Multilayer Mirrors; X-ray microscope; Materials science; Teknisk materialvetenskap;

    Abstract : A part of the Ph.D. project focused on growth and characterization of metal multilayers is presented in this licentiate thesis. The main interest in carrying out this research is to develop highly reflective normal-incidence condenser mirrors for soft X-ray microscopy studies in the water window (λ=2. READ MORE

  4. 2. Materials Science of Multilayer X-ray Mirrors

    Author : Naureen Ghafoor; Jens Birch; Claude Montcalm; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soft X-rays; Multilayer mirrors; Magnetron sputtering; Interface engineering; Materials science; Teknisk materialvetenskap;

    Abstract : This thesis treats the reflective and structural properties of multilayer structures. Soft X-ray multilayer mirrors intended as near-normal incidence reflective optics and polarizers in the water window (λ=2.4-4.4 nm) are the main focus. READ MORE

  5. 3. Mechanical properties and thermal stability of reactive arc evaporated Ti-Cr-Al-N coatings

    Author : Rikard Forsén; Magnus Odén; Naureen Ghafoor; Greger Håkansson; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This licentiate thesis reports experimental and theoretical work on the high temperature mechanical properties and the thermal stability of cubic (c)-(Ti-Cr-Al)1-N1 coatings. It is demonstrated that it is possible to tailor and improve the properties of hard nitride coatings by different degrees of multicomponent alloying. READ MORE

  6. 4. Multicomponent Alloying for Improved Hard Coatings

    Author : Rikard Forsén; Magnus Odén; Naureen Ghafoor; Mats Johansson; Jochen Schneider; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Coatings are vital to protect and to increase the productivity of cutting tools in high speed and dry cutting applications. During the cutting operation the temperature may exceed 1000 ºC it is therefore necessary that the coatings withstand high temperatures. READ MORE
