Journal ArticleDOI
Comparative study of passive films of different stainless steels developed on alkaline medium
TL;DR: In this paper, the evolution of the passive films formed on AISI 304L and duplex stainless steel SAF 2205 in NaOH 0.1 M was investigated using cyclic voltammetry, electrochemical impedance spectroscopy (EIS) and X-ray photoelectron spectrography (XPS).
Journal ArticleDOI
High frequency impedance spectroscopy study of passive films formed on AISI 316 stainless steel in alkaline medium
TL;DR: In this article, cyclic voltammetry, impedance spectroscopy and X-ray photo-electron spectrographs were used to study passive films formed on AISI 316 in deaerated 0.1 M NaOH solution.
Journal ArticleDOI
The effect of Ni in the electrochemical properties of oxide layers grown on stainless steels
TL;DR: In this article, the influence of Ni in the electrochemical behavior of three different stainless steels in alkaline medium was analyzed and it was shown that Ni modifies the conductivity of the oxide layers, promoting the formation of more resistive oxide films.
Journal ArticleDOI
Effect of high energy ball milling on the morphology, microstructure and properties of nano-sized TiC particle-reinforced 6005A aluminium alloy matrix composite
TL;DR: In this paper, the presence of n-TiC particles had a marked influence on the powder morphology, average particle size and microstructure of the matrix during the milling process.
Journal ArticleDOI
Long-term behaviour of AISI 304L passive layer in chloride containing medium
TL;DR: In this article, the behaviour and evolution of passive films generated on AISI 304L for a long immersion time in chloride containing media were studied for a combination of electrochemical (cyclic voltammetry and electrochemical impedance spectroscopy) and surface analysis techniques (AFM and XPS) in order to analyse the changes that chlorides induce in those films as immersion time increases.
