Effect of laser structured micro patterns on the polyvinyl butyral/oxide/steel interface stability
Hagen, Catalina Hoem Musinoi; Knudsen, Ole Øystein; Zavieh, Amin; Pfleging, Wilhelm (Peer reviewed; Journal article, 2020)This work investigated the effect of steel substrate topography and roughness on cathodic disbonding resistance and wet adhesion of the polyvinyl butyral/oxide/steel interface. Laser structuring was employed to pattern ... -
Experimental comparison of gaseous and electrochemical hydrogen charging in X65 pipeline steel using the permeation technique
Koren, Erik Aas; Hagen, Catalina Hoem Musinoi; Wang, Dong; Lu, Xu; Johnsen, Roy; Yamabe, Junichiro (Peer reviewed; Journal article, 2023)Herein, hydrogen uptake and diffusivity in X65 pipeline steel were investigated using the permeation technique under different hydrogen charging conditions. Hydrogen charging was performed using hydrogen gas at different ... -
Investigating electrochemical charging conditions equivalent to hydrogen gas exposure of X65 pipeline steel
Koren, Erik Aas; Hagen, Catalina Hoem Musinoi; Wang, Dong; Lu, Xu; Johnsen, Roy (Journal article; Peer reviewed, 2023)In this study, we systematically investigate electrochemical hydrogen charging conditions equivalent to hydrogen gas pressures relevant for hydrogen transportation in X65 pipeline steel. By performing hydrogen gas permeation, ... -
The effect of surface roughness on corrosion resistance of machined and epoxy coated steel
Hagen, Catalina Hoem Musinoi; Hognestad, Asbjørn; Knudsen, Ole Øystein; Sørby, Knut (Journal article; Peer reviewed, 2019)By incorporating periodic micro-patterns on steel substrates, the effect of surface roughness on corrosion resistance of a two-component polyamine cured epoxy mastic coating has been studied. Machining was employed to ...
