  1. 1. Oxidation kinetics of nickel particles

    Författare :Richard Karmhag; Uppsala universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Materials science; Oxidation; kinetics; nickel; particles; UFP; solar absorber; Materialvetenskap; Materials science; Teknisk materialvetenskap; Solid State Physics; fasta tillståndets fysik;

    Sammanfattning : Nanoparticles have an immense surface to volume ratio. This is a key factor to the new properties of some materials made up of such particles. The oxide layer formed on all materials will have a large influence on the behaviour of these materials. The layer isadvantageous in some cases but causes problems in other. LÄS MER

  2. 2. On high temperature oxidation resistance : Towards the materials genome of high temperature alloys

    Författare :Samuel Hallström; John Ågren; Roger Reed; KTH; []

    Sammanfattning : The efficiency of a heat engine increases with increasing service temperature. This leads to a demand for material that can withstand aggressive environments and sometimes also high load at higher and higher temperature. That is the rationale for the work of this thesis.

  3. 3. High Temperature Corrosion of FeCrAl Alloys: The influence of water vapour and alkali salt

    Författare :Niklas Israelsson; Chalmers University of Technology; []
    Nyckelord :pre-oxidation; FeCrAl; kinetics; high temperature corrosion; KCl; water vapour; alumina; oxidation;

    Sammanfattning : The corrosive environment in biomass- and waste-fired boilers has been known for several years. The traditionally used FeCr and FeNiCr steels show limited performance in the aggressive environment that contains more H2O and alkali salts than traditional fuel. LÄS MER

  5. 5. Synthesis of AlON and MgAlON Ceramics and Their Chemical Corrosion Resistance

    Författare :Xidong Wang; KTH; []
    Nyckelord :AlON; MgAlON; Thermodynamics; Oxidation; Slag corrosion;

    Sammanfattning : In view of the excellent mechanical, chemical and opticalproperties, AlON (Aluminum oxynitride) as well as MgAlON(Magnesium Aluminum oxynitride) have drawn the attention ofmaterials scientists in past decades. In this thesis,thermodynamic properties, synthesis and corrosion resistance tooxygen and slag of AlON and MgAlON ceramics have beeninvestigated. LÄS MER
