Comparative electrochemical and thermodynamic study of cold-rolled steel, Al alloy AA5754, and Zn corrosion in fluoride and chloride solutions
Ana Kraš, Ingrid Milošev
Izvirni znanstveni članek
Oznake: bicarbonate;pitting;complexation;
This study investigates the effects of fluoride and chloride ions on the corrosion of cold-rolled steel, aluminium alloy AA5754, and zinc, using ammonium bicarbonate as a buffer at pH 4 and compares electrochemical findings with thermodynamic calculations of E-pH diagrams. The distinct electrochemic ...

Characterisation of the deposition and protection performance of Zr conversion coatings on steel and zinc substrates using the response surface methodology
Ana Kraš, Davorin Kramar, Ingrid Milošev
Izvirni znanstveni članek
Oznake: response surface methodology;conversion coatings;thermodynamic data;
The response surface methodology (RSM) was used to explore the experimental space, characterise the influence of deposition and drying conditions on corrosion resistance, and evaluate the interactions between these factors for zirconium conversion coatings on cold-rolled steel and zinc. A combinatio ...

Experimental approach and assessment of Zr conversion coatings on Al alloy using response surface methodology
Ana Kraš, Davorin Kramar, Ingrid Milošev
Izvirni znanstveni članek
Oznake: aluminij;EIS (elektrokemijska impedančna spektroskopija);metodologija odzivne površine;pretvorne prevleke;aluminium;EIS (Electrochemical Impedance Spectroscopy);response surface methodology;conversion coatings;
This study extended the use of response surface methodology (RSM) to explore the experimental space, identify optimal conditions for deposition and drying, and assess factor interactions for zirconium conversion coatings on aluminium alloy 5754. Corrosion resistance in a dilute Harrison's solution w ...

Polymerised forms in the zirconium conversion coatings on cold-rolled steel
Ana Kraš, Ingrid Milošev, Antoine Seyeux, Philippe Marcus
Izvirni znanstveni članek
Oznake: fizikalna kemija;polimeri;jeklo;
This study validates the proposed polymerised structure, including tetrameric polynuclear species, of solid amorphous oxyhydroxide zirconium conversion coatings on cold-rolled steel using ToF-SIMS. Tetramers are formed at pH near 4 (and possibly higher), with thickness increasing over extended conve ...
