    • Corrosion of Copper and Oxidation of Dielectric Liquids in High Voltage Transformers 

      Tronstad, Ingvild (Doktoravhandlinger ved NTNU, 1503-8181; 2013:196, Doctoral thesis, 2013)
      Breakdowns in high voltage transformers are of major concern. It is therefore a goal to prevent this from happening. Chemical degradation (e.g. oxidation, hydrolysis and corrosion) of the insulation systems and windings ...

    • Corrosion of Thermally Sprayed Aluminum in Flowing Seawater 

      Holager, Cathrine Selina (Master thesis, 2012)
      Raw sea water can be pumped into subsea wells where pressure drops have occurred to increase the pressure again and thereby the production rate. Thermally sprayed aluminum (TSA) is considered as internal corrosion protection ...

    • Corrosion Prevention in Closed Energy Systems - Electrolysis Removal of Dissolved Oxygen in Water 

      Magnus, Tobias Henrich; Høivik, Gard Myhre (Bachelor thesis, 2023)
      Denne oppgaven fokuserer på hvordan korrosjon i lukkede energianlegg kan forebygges. Dette gjøres ved å redusere nivået av oppløst oksygen (DO) i vannet som sirkulerer i anlegget. For å gjennomføre dette ble det brukt en ...

    • Corrosion Properties of Extruded Aluminium Alloys Enabling Post-Consumer Scrap Materials 

      Hylen, Frida (Master thesis, 2023)
      Dette prosjektet undersøker hvordan inkorporering av skrapmaterialer (post-consumer scrap, PSC) i aluminiumslegeringer påvirker legeringenes korrosjonsegenskaper. Inkludering av PCS i aluminiumslegeringer kan bidra til en ...

    • Corrosion protection by coatings in multiphase pipelines 

      Faisal, Aws Yonis (Master thesis, 2009)

    • Corrosion Protection of Machined Steel Surfaces 

      Andersen, Silje Bergset (Master thesis, 2017)
      Protection of smooth, machined surfaces is challenging as the surfaces do not have the roughness required to provide proper adhesion between the substrate and the coating. This gives poor corrosion resistance and lower ...

    • Corrosion protection of metals/alloys by EPD (electrophoretic deposition) 

      Aas, Linda Berg (Master thesis, 2014)
      A solid oxide fuel cell consists of multiple cells stacked on top of each other. Between the individual cells is an interconnect component. In intermediate temperature solid oxide fuel cells, this component is made of ...

    • Corticosterone mediates carry-over effects between breeding and migration in the kittiwake Rissa tridactyla 

      Schultner, Jannik; Moe, Børge; Chastel, Olivier; Tartu, Sabrina; Bech, Claus; Kitaysky, Alexander S. (Journal article; Peer reviewed, 2014)
      Carry-over effects, i.e. when processes in one season influence processes in the next, are believed to have important effects on behavior and fitness in animals. Despite an increasing interest in the identification of ...
