  1. 1. Fabrication and Corrosion Properties of Nickel Silicides Thin Films

    Författare :Eric Tam; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nickel silicides; ion-beam sputter deposition; potentiodynamic polarisation measurements; X-ray photoelectron spectroscopy; corrosion.; thin films;

    Sammanfattning : Surface engineering is a vital issue in engineering materials design. The enhancement of surface properties extends the materials lifetime and improves the materials performance without changing the bulk properties. Thin film deposition is one of the most commonly applied techniques in this field. LÄS MER

  3. 2. Tailoring of Transition Metal Silicides as Protective Thin Films on Austenitic Stainless Steel

    Författare :Eric Tam; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Rockwell-C adhesion test; X-ray diffractrometry XRD ; Pretorius’ effective heat of formation EHF model; Ion-beam sputter deposition IBSD ; Reciprocating sliding wear test; Corrosion; Stainless steels; Thin films; Tribology; Transition metal silicides; X-ray photoelectron spectroscopy XPS ; Potentiodynamic polarisation measurements;

    Sammanfattning : The objective of this study is to make use of transition metal silicides in a novel way as protective thin films on engineering metals. It can then be possible to take advantage of the potentially good corrosion resistance of metal silicides while compensating for their brittle nature by the ductile bulk material. LÄS MER

  4. 3. Self-Assembled and Selective-Area Growth of Group III-Nitride Semiconductor Nanorods by Magnetron Sputter Epitaxy

    Författare :Elena Alexandra Serban; Ching-Lien Hsiao; Jens Birch; Per Persson; Lars Hultman; Eva Monroy; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The III-nitride semiconductor family includes gallium nitride (GaN), aluminum nitride (AlN), indium nitride (InN), and the related ternary and quaternary alloys. The research interest on this group of materials is sparked by the direct bandgaps, and excellent physical and chemical properties. LÄS MER
