Journal ArticleDOI
Modelling steel corrosion damage in soil environment
TL;DR: In this paper, a mathematical model to estimate the localized corrosion damage propagation in buried structures has been developed considering physicochemical variables of the environment observed in the field (pH, resistivity, redox potential, and electric potential at the soil-metallic structure interface).
Journal ArticleDOI
A modified Nafion membrane with in situ polymerized polypyrrole for the direct methanol fuel cell
TL;DR: In this paper, Nafion membranes were modified by the in situ electrodeposition of polypyrrole inside the membrane pores and on the anode side only, in order to prevent the cross-over of methanol in the direct methanoline fuel cell (DMFC).
Journal ArticleDOI
Hot corrosion behaviour of Fe–Al based intermetallic in molten NaVO3 salt
Marco Antonio Espinosa-Medina,G. Carbajal-De la Torre,H. B. Liu,A. Martinez-Villafañe,J. G. Gonzalez-Rodriguez +4 more
TL;DR: The hot corrosion of sprayed Fe-40 (at.%)Al intermetallic alloy with additions of boron and alumina whiskers in molten NaVO3 at 700°C has been evaluated by potentiodynamic polarization curves and electrochemical impedance spectroscopy, EIS, techniques as mentioned in this paper.
Journal ArticleDOI
High temperature corrosion performance of FeAl intermetallic alloys in molten salts
M. Amaya,Marco Antonio Espinosa-Medina,J. Porcayo-Calderon,Lorenzo Martinez,J.G. Gonzalez-Rodriguez +4 more
TL;DR: In this paper, the corrosion performance of FeAl base intermetallic alloys fabricated by spray-atomization and deposition during their immersion in molten NaVO3, 80% (wt.%) sodium pentoxide (V2O5) +20% sodium sulfate (Na2SO4) and pure Na 2SO4 in the temperature range of 600-1000 ǫ during 200 h was investigated.
