Corrosion fatigue of an extruded 7046 alloy
(Master thesis, 2018)The corrosion fatigue properties of a 7046 alloy were investigated and compared to previously reported work by SINTEF on the same alloy tested in air. To establish the corrosion fatigue properties, samples were either ... -
Corrosion Fatigue of Extruded AA6082 Aluminium Alloy - The effects of Surface Roughness: Machined, Punched, and Counter Trimmed Surfaces
(Master thesis, 2017)The aim of this master s thesis is to investigate the corrosion fatigue properties of an extruded AA6082 alloy. Surface roughness deeply affects fatigue and corrosion fatigue. Surface roughness depends on the shaping ... -
Corrosion in musical instruments at Ringve Museum
(Bachelor thesis, 2021)Formålet med denne bachelor oppgaven var å undersøke et korrosjonsproblem Ringve museum har hatt på pianostrenger i piano. Korrosjonen ved museet har hovedsakelig vært der pianotråden er i kontakt med filt eller lær. Det ... -
Corrosion of Thermally Sprayed Aluminum in Flowing Seawater
(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
(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 Prevention in Closed Energy Systems - Optimization of Electrolysis for Removal of Dissolved Oxygen in Water
(Bachelor thesis, 2024)Lukkede energianlegg har som formål å overføre energi samtidig som de forblir isolerte fra omgivelsene når det gjelder stoffutveksling. Vanligvis brukes vann som det primære mediumet for energioverføring, med rør som ... -
Corrosion Properties of Extruded Aluminium Alloys Enabling Post-Consumer Scrap Materials
(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
(Master thesis, 2009) -
Corrosion Protection of Machined Steel Surfaces
(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)
(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 ... -
Cost-effective electrodes for alkaline water electrolysis
(Doctoral theses at NTNU;2022:16, Doctoral thesis, 2022)Green hydrogen production using water electrolysis has potential to be the key component in storing and coupling renewable energy to the transportation and chemical sectors. Alkaline water electrolysis offers a relatively ... -
Coupled Ion Transport in Concentrated PEO-LiTFSI Polymer Electrolytes
(Peer reviewed; Journal article, 2023)Understanding how microscopic mechanisms govern macroscopic transport properties is important for development of improved electrolytes for Li-ion batteries. The archetypal polymer electrolyte PEO–LiTFSI has been investigated ... -
Coupled Transport in Li-ion Battery Electrolytes
(Doctoral theses at NTNU;2024:187, Doctoral thesis, 2024)Electrolytes are materials that contain mobile charge carriers – ions. The electrolyte in lithium-ion batteries enables the transport of positive Li+ ions in between the electrodes during battery operation. The transport ... -
Coupling and competition between ferroelectricity, magnetism, strain, and oxygen vacancies in AMnO3 perovskites
(Journal article; Peer reviewed, 2016)We use first-principles calculations based on density functional theory to investigate the interplay between oxygen vacancies, A-site cation size/tolerance factor, epitaxial strain, ferroelectricity, and magnetism in the ... -
Creep deformation of an additively manufactured nickel-based superalloy
(Master thesis, 2022)To versjoner av en nikkelbasert superlegering ble produsert med additiv tilvirkning og karakterisert etter sigetesting med SEM og atomprobetomografi. De to legeringene ble kalt CB og C da hovedforskjellen i mellom dem var ... -
Crevice corrosion of AISI 316L and 22Cr - the effect of temperature, chloride concentration, pH and oxygen content
(Master thesis, 2020)Korrosjonsresistente legeringer, som for eksempel rustfrie stål, blir ofte brukt i offshore-installasjoner på grunn av deres høye motstand mot generell korrosjon. Rustfrie stål er imidlertid utsatt for lokal korrosjon, som ... -
Cristobalite formation on quartz crucibles inner surface for CZ solar cell ingot production
(Master thesis, 2017)Cristobalite, the stable high temperature polymorph of quartz, is formed on the surface of fused quartz crucibles used for the growth of monocrystalline silicon ingots by the Czochralski process. When not controlled and ... -
