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 Cu2+ on deposition mechanism and structure of ZrO2-based conversion coatings on AA6060 aluminium alloys and their susceptibility to filiform corrosion

Mysliu, Erlind; Storli, Kathrine Sletteberg; Skogøy, Hanna Marie; Kubowicz, Stephan; Svenum, Ingeborg-Helene; Lunder, Otto; Erbe, Andreas (Peer reviewed; Journal article, 2024)

Zirconium oxide-based conversion coatings (CCs) were prepared from hexafluorozirconic acid, H2ZrF6, with and without CuII as an additive. The CCs were prepared on primary and recycled AA6060. The deposition mechanism, ...

Effect of order and disorder on degradation processes of copper phthalocyanine nanolayers

Grzadziel, Lucyna; Krzywiecki, Maciej; Genchev, Georgi; Erbe, Andreas (Journal article; Peer reviewed, 2017)

The impact was examined of surface ordering of 50 nm-thick copper phthalocyanine (CuPc) layers on the layer's susceptibility to ambience-induced degradation processes. The surface morphology of CuPc layers obtained by ...

Electrochemical analysis of aluminium alloy 5182 and 6016 with different surface treatments in 0.1 M NaCl electrolyte

Warloe, Sarah (Master thesis, 2018)

Replacing steel parts in cars with aluminium (Al) can reduce the weight by up to 50 % and contribute to decreased CO2 emissions. Aluminium is also easily and inexpensively recyclable. A lot of research is therefore conducted ...

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 ...

Electrochemical contrast switching between black and white appearance of gelatin-covered zinc

Ksiazkiewicz, Agnieszka Natalia; Fernandez-Solis, Christian; Erbe, Andreas (Peer reviewed; Journal article, 2020)

Zinc and its alloys are widely used in the surface protection of metallic structural materials. Thus, zinc is an interesting and relevant candidate material for preparing stimuli-responsive surfaces. In this work, the ...
