  1. 11. Aluminium alloys ability to catalyse the oxidation of biodiesel : Development of a procedure to test alloys

    Master-uppsats, KTH/Kraft- och värmeteknologi

    Författare :Ivan Khudur; [2017]
    Nyckelord :Accelerated aging; aluminium; aluminium alloys; biodiesel; catalysis; copper; RME; oxidation stability; test method;

    Sammanfattning : Biodiesel is a renewable and biodegradable fuel that has the possibility to replace conventional diesel fuel and reduce the environmental pollution. Despite its environmental benefits, it has been shown to cause damage to the vehicle engines, due to its oxidative properties. LÄS MER

  3. 12. Applying Thermal Diffusion Galvanization on Wood Screws : Effects on Corrosion Resistance and Mechanical Properties

    Kandidat-uppsats, KTH/Materialvetenskap

    Författare :Benjamin Solem; Ante Vallien; Philip Wernstedt; [2016]
    Nyckelord :galvanization; thermal diffusion galvanization; TDG; corrosion; galvanisering; diffusion; rostskydd;

    Sammanfattning : Today, fastening articles such as screws and nails are treated with different surface coatings to withstand corrosion. The Swedish distributor ESSVE® Produkter AB uses a nano coating called CorrSeal™ for high corrosion protection of their screws. LÄS MER

  4. 13. Infuence of surface and crystal structure on the conductivity of individual InAs and InP nanowires

    Kandidat-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Författare :Lena Isabel Tamara Kral; [2015]
    Nyckelord :semiconducting nanowire; zinc blende; wutzite; hydrogen cleaning; STM; oxidation; photovoltaic response; photovoltaics; top contact method; InAs; nanowire; InP; Physics and Astronomy;

    Sammanfattning : To satisfy the great need for (opto-)electronic devices to become smaller and more efficient in energy and price, research is done on semiconducting III-V nanowires (NWs). Electrical devices using NWs show noteworthy assets being fast-paced with high-speed electronics and low power consumption, one of which are high-efficient solar cells at a moderate price. LÄS MER

  5. 14. Kontroll av zinkskikt på monterat räckesmaterial

    M1-uppsats, KTH/Byggteknik och design

    Författare :Shida Fathi; [2014]
    Nyckelord :galvanizing; zink layer; layer thickness; corrosion; iron; zinc alloy; silicon content; Swedish road and bridge railing compound; Arenastad; mean; standard deviation; confidence; confidence level; varmförzinkning; zinkskikt; skikttjocklek; korrosion; järn; zink; legering; kiselhalt; svenska väg och broräckesföreningen; arenastad; medelvärde; standardavvikelse; konfidensintervall; konfidensgrad;

    Sammanfattning : Kontroll av zinkskikt på monterat räckesmaterial som görs ute i fält saknar en fastställd metod. Zinktjockleken har ett minimum tjocklekskrav enligt den svenska standarden ISO 1461:2009, som bestäms av dimensionen på ståldetaljens tjocklek. LÄS MER

  7. 15. Rostfria stålkonstruktioner och rostskyddsbehandling av stålkonstruktioner enligt Eurocode

    Uppsats för yrkesexamina på grundnivå, KTH/Byggteknik och design

    Författare :Niklas Karlsson; Jenny Öjemyr; [2012]
    Nyckelord :stainless steel; anticorrosive painting; zinc coating; corrosion; corrosive categories; Rostfritt stål; rostskyddsmålning; förzinkning; korrosion; korrosivitetsklasser;

    Sammanfattning : Steel is an excellent material to build with, but consideration must be given to the fact that unprotected steel corrodes, rusts, therefore, as a rule, the steel must be protected in some way. This can be done by reducing the tendency of the steel to corrode by using stainless steel or by treating the steel with a protection method. LÄS MER
