  1. 6. Barrier properties of model coatings using recycled iron oxide pigment

    Uppsats för yrkesexamina på grundnivå, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Nathalie Hagenfjärd; [2021]
    Nyckelord :Organic coatings; Iron oxide pigment; EIS; Barrier properties;

    Sammanfattning : The aim of this study was to compare the barrier properties of organic coatings with the same polymer matrix but different types of iron oxide particles, commercial and recycled. The work was carried out for the company SSAB with the aim of investigating whether the pigment Merox ferric oxide, which is produced in-house at the company during the pickling process, can be used and replace commercial iron oxide pigment.

  3. 7. Development of corrosion resistant coatings using natural biopolymer and pollen

    Master-uppsats, KTH/Materialvetenskap

    Författare :Alessandro Armani; [2020]
    Nyckelord :;

    Sammanfattning : Corrosion is a mechanism that highly reduces the lifetime of metals in different environments, especially in water or moisture environment. The worldwide maintenance cost due to corrosion is estimated in billions of dollars per year, and actual solutions in terms of coating usually contains toxic or environmentally harmful species.

  4. 8. Rengöring av fodernedfallsrör i tillväxtavdelningen : kan det ha en positiv inverkan på grisens hälsa och tillväxt?

    Kandidat-uppsats, SLU/Dept. of Biosystems and Technology (from 130101)

    Författare :Jennifer Sköld; [2018]
    Nyckelord :tillväxt; avvänjning; rengöring; foder; avvänjningsvikt; avvänjningsdiarré;

    Sammanfattning : Avvänjningen är en av de mest avgörande perioderna i en gris liv. Den hänger samman med en ökad risk för sjukdomar som t.ex. avvänjningsdiarré och en ökad antibiotikaanvändning. LÄS MER

  5. 9. Material characterization of multi-layered Zn-alloy coatings on fasteners : Effects on corrosion resistance, electrical conductivity and friction

    Master-uppsats, KTH/Materialvetenskap

    Författare :Ante Vallien; [2018]
    Nyckelord :ZnNi; zinc alloy; multi-layered coating; electrodeposited coating; fasteners; corrosion resistance;

    Sammanfattning : Electroplated zinc-alloy coatings have been used on fasteners in the automotive industry for many years. The coating often consists of three layers: a zinc-alloy layer, a passivation layer and a sealer or top-coat. LÄS MER

  7. 10. 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; copper; oxidation stability; RME; 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
