  1. 1. Thermal Barrier Coatings : Durability Assessment and Life Prediction

    Författare :Robert Eriksson; Sten Johansson; Michael Schütze; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Thermal barrier coating (TBC) systems are coating systems containing a metallic bond coat and a ceramic top coat. TBCs are used in gas turbines for thermal insulation and oxidation resistance. LÄS MER

  3. 2. Oxy-Fuel Combustion - The Control of Nitrogen Oxides

    Författare :Fredrik Normann; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; oxy-fuel; NOx; O2 CO2; combustion; emission; nitrogen oxides;

    Sammanfattning : Oxy-fuel combustion is one of the main candidates for carbon dioxide capture from power plants. In oxy-fuel combustion, oxygen diluted with recycled flue gas oxidizes the fuel. The elimination of air-borne nitrogen generates a flue gas that mainly consists of carbon dioxide and water. LÄS MER

  4. 3. Electrical properties of thermal oxides on SiC manufactured in an alumina furnace

    Författare :Fredrik Allerstam; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MOSFET; 6H-SiC; 4H-SiC; Silicon carbide; MOS; TDRC; CV; thermal dielectric relaxation current; interface states;

    Sammanfattning : A process to achieve high inversion channel mobility in 4H-SiC MOSFETs is needed to enable manufacturing of devices for high power applications. In this thesis, investigations on the electrical properties of oxides produced in an alumina furnace are presented. LÄS MER

  5. 4. Use of localised techniques to elucidate the influence of process variables on the corrosion of stainless steels

    Författare :Nuria Fuertes; Rachel Pettersson; Inger Odnevall; Stuart Lyon; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stainless steel; corrosion; passive film; thermal oxides; Volta potential; pickling; deformation; cold rolling; AM; SKPFM; SVET; Kemi; Chemistry;

    Sammanfattning : Several factors during steel manufacture and fabrication can alter the passivity and corrosion behaviour of stainless steels. These include alloying, deformation, welding and heat treatments. LÄS MER

  7. 5. Use of local electrochemical techniques for corrosion studies of stainless steels

    Författare :Nuria Fuertes; Rachel Pettersson; Mari Sparr; Ulf Kivisäkk; Yolanda Hedberg; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stainless steel; passive film; thermal oxides; work function; pickling; SKPFM; SVET; XPS; AES; Teknisk materialvetenskap; Materials Science and Engineering;

    Sammanfattning : The excellent corrosion resistance of stainless steels arises from the presence of a passive film on its surface. Above 10.5wt% Cr a chromium oxide of 1-3 nm is formed on the surface of the metal that in case of damage will reform and hinder further dissolution of the metal. LÄS MER
