TL;DR: In this article, an original experimental set-up was designed to discriminate the particles as a function of the levels of velocity to investigate the influence of this parameter on adhesion, which can change dramatically depending on particle position from the core of the jet.

TL;DR: In this article, the effect of dissolved hydrogen (DH) levels on the Ni/NiO phase transition was investigated by employing electrochemical and exposure experiments, and the results showed that increasing DH in water decreased the thickness and the ionic defect transport resistance of the oxide film, in conjunction with the increase of Cr- but decrease of Ni-concentrations in the oxide.

TL;DR: In this paper, the role of microstructure and water chemistry in stress corrosion cracking in Alloy 182-low alloy steel (LAS) dissimilar weld joint in 288°C water was investigated by experiments and finite element simulation.

TL;DR: In this paper, the authors showed that the changes in corrosion behavior and microstructure of the oxide film were most likely due to the hydrogen enhanced preferential dissolution of Cr cations in the water.

TL;DR: In this paper, Mott-Schottky analysis and X-ray photoelectron spectroscopy (XPS) were used to investigate the effects of hydrogen on the anodic behavior of a one-dimensional (1D) 25% cold worked (CW) Alloy 690 thermal treated (IT) in a boric acid and sodium sulphate solution at 60 degrees C.
