  1. 1. Chemical vapor deposition of hard coatings : Development of W(C,N) coatings for cemented carbide and TiN deposition on a CoCrFeNi substrate

    Författare :Katalin Böőr; Mats Boman; Markku Leskelä; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : There is a constant need for cutting tool material development to be able to machine new materials and improve the metal cutting efficiency. Inserts of indexable cutting tools usually consist of WC-Co cemented carbide (cc) with μm thick layers of ceramic coatings. LÄS MER

  3. 2. Simulations of Silicon Carbide Chemical Vapor Deposition

    Sammanfattning : Most of the modern electronics technology is based on the semiconducting material silicon. The increasing demands for smaller electronic devices with improved performance at lower costs drive the conventional silicon technology to its limits. LÄS MER

  4. 3. Epitaxy and characterization of SiGeC layers grown by reduced pressure chemical vapor deposition

    Författare :Julius Hållstedt; KTH; []
    Nyckelord :Silicon germanium carbon SiGeC ; Epitaxy; Chemical vapor deposition CVD ; Loading effect; High resolution x-ray diffraction HRXRD ; Hall measurements; Atomic force microscopy AFM .;

    Sammanfattning : Heteroepitaxial SiGeC layers have attracted immenseattention as a material for high frequency devices duringrecent years. The unique properties of integrating carbon inSiGe are the additional freedom for strain and bandgapengineering as well as allowing more aggressive device designdue to the potential for increased thermal budget duringprocessing.

  5. 4. Surface-Controlled Chemical Vapor Deposition of Silicon Carbide

    Författare :Jing-Jia Huang; Henrik Pedersen; Urban Forsberg; Örjan Danielsson; Ulf Jansson; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Polycrystalline cubic silicon carbide, 3C-SiC, has long been investigated in the field of hard coating materials. The typical synthesis method for 3C-SiC coatings is thermal chemical vapor deposition (CVD) using either multicomponent precursors, e.g. methyltrichlorosilane, or a combination of single component precursors, e.
