  4. 2. High Temperature Corrosion of Cast Irons and Steels

    Author : Frédéric Tholence; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; high temperature corrosion; cast steel; austenitic stainless steel; SiMo; cast iron; oxidation; exhaust gases; Ni-resist; LCF; ferritic stainless steel;

    Abstract : During the last decades, tougher competition and stiffer government policies have forced the automotive industry into a race for safer, cleaner and more fuel-efficient vehicles at low cost. As a consequence, exhaust systems should resist to increased working temperatures. READ MORE

  5. 3. Microscopy of high temperature oxidation of iron and some stainless steels

    Author : Torbjörn Jonsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; water vapour; sulphur dioxide; FIB; X20; stainless steel; 353MA; EDX; KCl; FIB SEM; SEM; microstructure; TEM; iron; High-temperature oxidation; in-situ ESEM;

    Abstract : This thesis concerns the high temperature oxidation of iron and some stainless steels. The oxide scales, as well as the subjacent metal, were investigated using a range of electron and ion microscopy techniques, including SEM, TEM, EDX and FIB. The aim was to link the microstructural observations to the oxidation mechanisms of the materials. READ MORE

  6. 4. The Effects of Morphology and Surface Oxidation of Stainless Steel Powder in Laser Based-Powder Bed Fusion

    Author : Dmitri Riabov; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; additive manufacturing; powder surface; 316L stainless steel; oxides; oxidation; laser based-powder bed fusion; morphology; powder properties; powder production;

    Abstract : Laser based-powder bed fusion (LB-PBF) is one of the many techniques within additive manufacturing (AM) that allows for near net shape manufacturing of metallic components. By using powder feedstock, it is possible to spread thin layers of powder and further selectively fuse powder in a repetitive manner until the component is completed. READ MORE

  7. 5. Corrosion and Surface Studies of Stainless Steel and Chromium Carbide Thin-Films

    Author : Jonas Högström; Leif Nyholm; Kristina Edström; Patrik Schmutz; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; corrosion; electrochemistry; thin film; stainless steel; passive film; chromium carbide; carbon oxidation; surface; depth profile; XPS; SEM; EQCM; sputtering;

    Abstract : Although the passive films that form on stainless steels have been extensively studied, the concentration depth profiles are not fully understood. Their thinness makes passive films hard to study, but angle-resolved X-ray photoelectron spectroscopy (ARXPS) is a non-destructive technique that can be used to obtain depth information. READ MORE
