Corrosion and Wear Behavior of TiO<inf>2</inf>/TiN Duplex Coatings on Titanium by Plasma Electrolytic Oxidation and Gas Nitriding
(Peer reviewed; Journal article, 2022)In this study, corrosion and wear behavior of three kinds of coatings by two processes, namely, plasma electrolytic oxidation (PEO) coatings (Ti/TiO2), gas nitriding coating (Ti/TiN), and the duplex coating (Ti/TiO2-N) by ... -
Corrosion and wear protection of wheel axles on trains
(Master thesis, 2016)Wheel axles are critical components on the train, and subjected to strict inspections and maintenance. With its placement underneath the train units, they are naturally susceptible of shocks and impact loads from ice, snow, ... -
Corrosion Fatigue of Fine Grain Mg-Zn-Zr and Mg-Y-Zn Alloys
(Journal article; Peer reviewed, 2018)Corrosion fatigue data for magnesium alloys are still scarce. The present communication reports the results of microstructural investigations and fatigue testing of the fine grain Mg-Zn-Zr (ZK60) alloy after multiaxial ... -
Corrosion of AISI 316L in Fish Processing Facilities
(Master thesis, 2023)Fiskeforedlingsindustrien bruker mye prosessutstyr og rør konstruert av AISI 316L og AISI 340L rustfritt stål. Produksjonsutstyret er jevnlig utsatt for sjøvann, noe som har forårsaket korrosjons-relaterte problemer i flere ... -
Corrosion of Aluminium AA5083 and AA6082 in Seawater - Effect of Temperature and Crevice
(Master thesis, 2017)The results from this study showed that a temperature of 50 degrees Celsius had an effect on both AA5083 and AA6082. The increased temperature increased the corrosion severity on the alloys. This could for instance be seen ... -
