Copper in compensated p- and n-type Czochralski silicon: Diffusivity, influence on the majority charge carrier density and mobility
(Peer reviewed; Journal article, 2022)Copper contamination risks are present throughout the whole crystalline silicon solar cell process flow, namely during ingot growth processes using recycled feedstock, wafer sawing and metallisation. Copper is a fast-diffusing ... -
Correlated subgrain and particle analysis of a recovered Al-Mn alloy by directly combining EBSD and backscatter electron imaging
(Journal article, 2022)Correlated analysis of (sub)grains and particles in alloys is important to understand transformation processes and control material properties. A multimodal data fusion workflow directly combining subgrain data from electron ... -
Correlating laser energy with compositional and atomic-level information of oxides in atom probe tomography
(Peer reviewed; Journal article, 2023)Atom probe tomography (APT) is a 3D analysis technique that offers unique chemical accuracy and sensitivity with sub-nanometer spatial resolution. There is an increasing interest in the application of APT to complex oxides ... -
Correlating oriented grain number density of recrystallisation in particle-containing aluminium alloys
(Journal article; Peer reviewed, 2018)The recrystallized grain structure of Al–(Mn)–Fe–Si alloys after isothermal annealing was studied by electron backscatter diffraction (EBSD) technique. Statistical correlation suggests that the frequency of forming P-oriented ... -
Correlation between coke type, microstructure and anodic reaction overpotential in aluminium electrolysis
(Journal article; Peer reviewed, 2015)Although the anode process during aluminum electrolysis has a substantial overpotential that increases the energy demand and production cost of aluminum, properties of the coke that can influence the electrochemical ... -
Correlation between light absorption and electric charge in solid state electrochromic windows
(Journal article; Peer reviewed, 1999)Electrochromic windows based on different combinations of the electro chromic materials polyaniline (PANI), Prussian Blue (PB) and tungsten oxide (WO3), with the solid state polymer electrolyte poly(2 acrylam ido 2 methyl ... -
Corrosion and Cathodic Protection of Steel-Aluminium Galvanic Couples in Subsea Structures
(Master thesis, 2018)An increasing interest for use of aluminium in subsea structures has been seen the resent years, considering replacing some of the heavier steel components with aluminium. Due to good corrosion resistance and strength to ... -
Corrosion Behaviour of Aluminium-Steel Welded Joints
(Master thesis, 2018)Multi-material solutions is a hot research topic in the automotive industry. The possibility to combine the physical and mechanical properties of different materials in a car component can both increase passenger safety, ... -
Corrosion Development in Welded AA6082 Alloys
(Master thesis, 2013)AlMgSi alloys, frequently used as extruded profiles, generally show excellent corrosionresistance, as Mg is incorporated in the protective oxide layer, thus providing additionalstabilization. However, localized corrosion ... -
Corrosion Fatigue of AA6082 Aluminium Alloy: The Effects of Coating and Ti Additions
(Master thesis, 2019)Effektene av anodisering og organisk belegg (KTL) på korrosjonsutmattingsegenskapene til en ekstrudert AA6082 aluminiumslegering ble undersøkt. Ubelagte og anodiserte prøver med ekstra Ti i legeringen ble også testet. En ... -
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 ... -
