AC Induced Corrosion of Carbon Steel in 3.5wt% NaCl Electrolyte
Strandheim, Espen Oldeide (Master thesis, 2012)This paper deals with alternating current (AC) corrosion of low alloy carbon steel in 3.5 wt% NaCl electrolyte. Accelerated corrosion rates have been reported when exposed to AC and the corrosion mechanism is not well ... -
Alternating Current Corrosion of Aluminium Sacrificial Anodes
Forthun, Kari (Master thesis, 2013)Direct Electric Heating (DEH) is applied to subsea oil production and transmission pipelines to prevent freezing of hydrates as wax during productions shut downs. To prevent clogging, the pipes are heated by application ... -
Alternating Current Corrosion of Carbon Steel
Belland, Eirik (Master thesis, 2011)The objective was to investigate if the established theory concerning corrosion calculations and electrochemical behavior of carbon is valid when steel is exposed to AC in an electrolyte consisting of 3,5 wt% NaCl and ... -
Crevice corrosion of AISI 316L and 22Cr - the effect of temperature, chloride concentration, pH and oxygen content
Edvardsen, Marie Eugenie (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 ... -
Impressed current system for internal corrosion protection in monopiles for offshore windmills: Investigation of the calcareous deposits formation mechanism and behaviour in confined and partially open compartments
Cherif, Osema (Master thesis, 2022)Impressed current cathodic protection (ICCP) is a highly effective corrosion protection system for submerged structures. When polarising the steel to its immune state by applying a protective current, the interfacial pH ... -
Properties of TSA in natural seawater at ambient and elevated temperature
Wilson, Håvard; Johnsen, Roy; Torres Rodriguez, Cristian; Hesjevik, Sven Morten (Journal article; Peer reviewed, 2019)Electrochemical properties of thermal sprayed aluminium (TSA) coating were investigated in natural seawater at elevated temperatures with and without cathodic protection (CP). TSA has a low current density requirement when ... -
Transmission through an Electrochromic Window based on Polyaniline, Tungsten Oxide and a Solid Polymer Electrolyte
Jelle, Bjørn Petter; Hagen, Georg K; Hesjevik, Sven Morten; Ødegård, Rolf (Journal article; Peer reviewed, 1992)An electrochromic window was fabricated by combining polyaniline and tungsten oxide with a solid polymer electrolyte binding the two electrochromic materials together. Polyaniline and tungsten oxide were deposited ... -
