Assessment of the potential of hydrogen plasma charging as compared to conventional electrochemical hydrogen charging on dual phase steel [PDF]
Materials Science and Engineering: A, 2019 Abstract The present study evaluates the hydrogen induced damage by in-situ hydrogen plasma charging in dual phase (DP) steel. Cold deformation of 15% is applied on the material to change microstructural defects, such as dislocation density. The susceptibility to hydrogen embrittlement is hence evaluated for two material conditions, i.e. DP 0% and DP

Electrochemical hydrogen charging to simulate hydrogen flaking in pressure vessel steels [PDF]
Engineering Fracture Mechanics, 2019 The current study investigates hydrogen flaking in large forgings. Two industrially forged pressure vessel materials, exhibiting different segregation behavior are compared for this purpose. Electrochemical hydrogen charging is used to simulate the flakes, present in real-life applications, on a small scale. As such, the sensitivity of the materials to

Hydrogen charging of carbon and low alloy steel by electrochemical methods
Journal of Applied Electrochemistry, 2023 AbstractAtomic hydrogen can be the result of different processes like electroplating, chemical and electrochemical pickling treatments, in welding or by cathodic processes in corrosive fluids. Moreover, adsorption of atomic hydrogen can affect materials in contact with high pressure gaseous hydrogen. Once entered the material, atomic hydrogen interacts

Effect of electrochemical charging on the hydrogen embrittlement susceptibility of alloy 718 [PDF]
Acta Materialia, 2019 Abstract The susceptibility of age-hardened nickel-based Alloy 718 to hydrogen embrittlement was studied by the controlled electrochemical charging combined with slow strain-rate tensile tests (SSRT) and advanced characterization techniques. We proposed some novel ideas of explaining hydrogen embrittlement mechanisms of the studied material in regard
