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

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

    Abstract : 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. READ MORE

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

    Author : Eric Tam; Chalmers tekniska högskola; []
    Keywords : 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;

    Abstract : 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. READ MORE

  5. 3. Passivation of Austenitic Stainless Steel

    Author : Lena Wegrelius; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; stainless steel; chloride; molybdenum; passivation; hydrochloric acid; nitrogen; ESCA; dissolution;

    Abstract : The objective of this thesis is to study the corrosion resistance and passivation of high alloyed austenitic stainless steels exposed to hydrochloric acid. The introductory section gives a background to the subject; electrochemical measurements and surface analysis by the ESCA-technique (Electron Spectroscopy for Chemical Analysis). READ MORE
