Chromium coatings from trivalent chromium plating baths: Characterization and cathodic delamination behaviour
(Peer reviewed; Journal article, 2021)Novel two-layer chromium-based coatings comprised of a first layer containing chromium, oxygen and carbon (Cr-O-C) and an oxygen rich (Cr-O) topcoat were electrodeposited from trivalent chromium electrolyte. The complex ... -
Copper enriched by dealloying as external cathode in intergranular corrosion of aluminium alloy AA6005
(Journal article; Peer reviewed, 2019)The purpose of this work is to understand the role of Cu in the propagation mechanism of IGC on extruded alloy AA6005-T5. The constituent Cu segregates as a Cu-rich nanolayer, together with the formation of a solute depleted ... -
Effect of pre-oxidation on the oxidation resistance of Crofer 22 APU
(Journal article; Peer reviewed, 2018)The ferritic stainless steel Crofer 22 APU is attractive for the use as interconnects in solid oxide fuel cell stacks. The oxidation rate of this alloy in air at 800 °C was reduced by pre-oxidation at higher temperatures ... -
Effect of small concentrations of gallium and lead on anodic activation of aluminium in chloride solution
(Journal article; Peer reviewed, 2018)The presents objective is to investigate the combined effect of alloyed Pb and Ga on surface segregation by heat treatment and ensuing anodic activation of aluminium in chloride solution. Model alloys containing Pb and Ga, ... -
Evaluation of microstructural and environmental effects on the hydrogen uptake and desorption in high-strength carbon steels: A thermal desorption spectroscopy study
(Peer reviewed; Journal article, 2023)The hydrogen uptake in three high-strength carbon steels is studied after exposure to three different environments: an aqueous solution with CO2 bubbling, CO2/H2S bubbling, and cathodic charging without external gassing. ... -
Hole annihilation vs. induced convection: Breakdown of different contributions to the photocorrosion mechanism of oxide-covered iron
(Peer reviewed; Journal article, 2021)The mechanism behind corrosion rate increase of anodised iron under illumination has been studied by comparing photocurrents with corrosion currents from polarisation curves under controlled convection. Under illumination ... -
Role of cementite morphology on corrosion layer formation of high-strength carbon steels in sweet and sour environments
(Peer reviewed; Journal article, 2023)The effect of cementite morphology on the corrosion layer formation of four high-strength carbon steels was studied in an aqueous solution containing CO2 and CO2/H2S. The linear polarization resistance and weight loss data ... -
The durability of the thermally decomposed IrO2-Ta2O5 coated titanium anode in a sulfate solution
(Journal article; Peer reviewed, 2019)In this work, series of IrO2-Ta2O5 anodes were investigated. The catalytic activity towards oxygen evolution reaction (OER) of these anodes are determined by calcination temperature, coating loading (coating thickness), ... -
The multiple roles of an organic corrosion inhibitor on copper investigated by a combination of electrochemistry-coupled optical in situ spectroscopies
(Journal article; Peer reviewed, 2018)The interaction of the organic corrosion inhibitor 2-mercaptobenzothiazole (MBT) with copper in alkaline solution was investigated by in situ infrared (IR) and Raman spectroscopy, and in situ spectroscopic ellipsometry, ...
