Yilmaz, A. (author), He, X. (author), Pletincx, Sven (author), Hauffman, Tom (author), Sietsma, J. (author), Gonzalez Garcia, Y. (author)The role of prior austenite grain size (PAGS) on the passive layer properties of martensitic steels is studied. Electron backscatter diffraction analysis shows that PAGS between 5 and 66 µm were obtained after applying different heat treatments. The barrier properties of passive film deteriorate with grain refinement up to 28 µm, attributed to...journal article 2022

Yilmaz, A. (author), Ozkan, C. (author), Sietsma, J. (author), Gonzalez Garcia, Y. (author)The effect of ferrite-pearlite and ferrite-martensite phase combinations on the passive layer properties of low carbon steel is investigated in a 0.1 M NaOH solution. Heat treatments were designed to obtain ferrite-pearlite and ferrite-martensite microstructures with similar ferrite volume fractions. Potentiostatic polarisation and...journal article 2021

Yilmaz, A. (author), Traka, K. (author), Pletincx, S. (author), Hauffman, T. (author), Sietsma, J. (author), Gonzalez Garcia, Y. (author)The role of microstructural defects (dislocation density and grain boundary areas) on the passive film properties formed on cold- and hot-rolled interstitial free (IF) steels is investigated in 0.1 M NaOH solution. Electron backscattered diffraction (EBSD) shows higher microstructural defect density on cold-rolled samples. Potentiodynamic...journal article 2021

(author), Terryn, H.A. (author), Mol, J.M.C. (author)The bonding properties of zirconium- and titanium-based conversion coatings were evaluated using model conversion solutions of H<sub>2</sub>ZrF<sub>6</sub> and H<sub>2</sub>TiF<sub>6</sub> with addition of various organic additives (PAA, PVA, PVP). Macroscopic testing techniques such as contact angle and pull-off adhesion measurements were...journal article 2020

Coelho, L. B. (author), Fava, E. B. (author), Kooijman, A.M. (author), Gonzalez Garcia, Y. (author), Olivier, M. G. (author)The effect of sodium molybdate in inhibiting galvanic corrosion of Zn coating and mild steel is addressed. The inhibitor's performance was appraised by Zero Resistance Ammeter on HDG/mild steel galvanic coupling model in 0.05 M NaCl (+5 mM Na<sub>2</sub>MoO<sub>4</sub>) media. The effectiveness of Na<sub>2</sub>MoO<sub>4</sub> was evaluated...journal article 2020

Lampert, Felix (author), Christiansen, Alexander Bruun (author), Din, Rameez Ud (author), Gonzalez Garcia, Y. (author), Møller, Per (author)The efficiency of thin hydrogen silsesquioxane (HSQ) −based corrosion barrier coatings on 316L substrates after oxidative thermal curing at 400–550 °C in air was investigated. Infrared spectroscopy and electrochemical impedance spectroscopy showed that an increasing curing temperature leads to progressing coating densification, accompanied by...journal article 2017
