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 ... -
The effect of bird droppings on the corrosion of steel and aluminum used in offshore applications
Forr, Fredrik; Mysliu, Erlind; Nordlien, Jan Halvor; Erbe, Andreas (Peer reviewed; Journal article, 2022)Engineering materials in service are frequently exposed to bird droppings (BDs). In this study, the interaction has been studied of BDs from chicken with a carbon steel, AISI 316, 22% Cr duplex stainless steel (DSS), 25% ... -
Effect of Microstructure on the Performance of Corrosion Resistant Alloys
Kishan Roodbari, Marzieh (Master thesis, 2015)Corrosion by pitting in aluminum alloys is a very complex process that can be affected by various factors such as chemical composition and microstructure of the alloys. The electrochemistry and distribution of second phases ... -
Electrochemical behaviour of Mn-containing Al-alloys after different heat treatment
Willumsen, Halvor Frøhaug (Master thesis, 2022)Aluminium brukes ofte i varmevekslere i biler på grunn av lav vekt og god varmeledningsevne. Når varmevekslerne monteres blir de ulike delene loddet sammen. Varme fra denne loddeprosessen aktiverer metallet for anodiske ... -
Microstructural evolution of 3000 series multi-port extruded tubes during brazing cycles
Yang, Jiawei (Master thesis, 2017)The AA3xxx series alloys are known for the good corrosion resistance and widely used as heat exchanging material. However, 3xxx series alloys shows intergranular corrosion problem after brazing. In this project, a systematic ... -
Optimisation of Zn-Mn co-electrodeposition on aluminium utilising direct- and pulse current in alkaline and acidic electrolyte
Nordengen, Håkon (Master thesis, 2019)Aluminium som blir brukt i varmevekslere er utsatt for korrosjon i spesielt aggressive omgivelser. Beskyttelse av aluminiumoverflaten er viktig for å beholde mekaniske og kjemiske kvaliteter i prosessene den blir brukt ... -
Surface pretreatments and filiform corrosion mechanism of model recycled aluminium alloys
Mysliu, Erlind (Doctoral theses at NTNU;2024:224, Doctoral thesis, 2024)Filiform corrosion (FFC) is a type of localized corrosion process that affects metals such as aluminium, magnesium and steel under certain environmental circumstances. FFC often occurs in environments combining marine and ... -
The effect of bird droppings on the corrosion of structural materials used in offshore applications
Forr, Fredrik Oftedal (Master thesis, 2022)Den nåværende trenden i olje- og gassindustrien er at flere aktører ønsker å bygge automatiserte plattformer som er enten normalt ubemannet, eller ubemannet. Dette gir økte krav for design, som må kunne yte for lange ... -
Zinc-rich coatings for improved corrosion resistance of extruded aluminium heat-exchange tubing in acidified chloride solution
Stepanova, Mariia (Doctoral theses at NTNU;2017:294, Doctoral thesis, 2017)Thin walled heat exchanger Al alloy tubes, with solid-solution Zn-rich surface, are widely used by the automotive industry and are considered by the heat, ventilation, air-conditioning and refrigeration market. This work ...
