Alternating Current Corrosion of Aluminium Sacrificial Anodes
(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 Aluminum
(Master thesis, 2015)Formation of wax and hydrates due to production stops is a well-known problem in the oil industry. Conventionally the pipelines are heated beyond a critical temperature to avoid this problem. This is done by a method called ... -
Alternating Current Corrosion of Carbon Steel
(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 ... -
Alternating Current Corrosion of Steel in Seawater
(Master thesis, 2015)A challenge regarding the transportation of oil and gas in pipelines subsea is to keep the temperature high enough to avoid formation of wax and hydrates, which eventually will stop the flow. In 2000, Nexans introduced a ... -
Alternative Methods for Curing of TCO Thin Films
(Master thesis, 2014)Transparent conducting oxides have a unique combination of properties as they are both optical transparent in the visible region of the electromagnetic spectrum, and obtain a near-metallic conductivity. This makes them ... -
Alumina Dissolution in Cryolite Melts - Formation and Behavior of Rafts
(Master thesis, 2018)Alumina is the raw-material used for aluminum production in the Hall-Héroult process. Though the process is used for several years, some phenomena is not fully investigated yet. One of those is the formation of floating ... -
Alumina Dissolution in Cryolite Melts: Effects of Secondary Alumina Properties on Dissolution and Raft Formation
(Master thesis, 2022)I Hall-Héroult prosessen som brukes til å produsere primær alumina, er oppløsning av råmaterialet alumina en av de viktigste delene av selve produksjonsprosessen. Et fenomen som ikke er fullt forstått enda innen oppløsning ... -
Aluminizing of plain carbon steel: Effect of temperature on coating and alloy phase morphology at constant holding time
(Master thesis, 2012)Aluminized steel possesses excellent physical, chemical and mechanical properties as compared to plain carbon steel. This type of steel has found application in high temperature, oxidizing and corrosive environments. In ... -
