Cathodic hydrogen charging of Inconel 718

AIMS Materials Science, 2016
The nickel based superalloy IN718 is known to be prone to hydrogen sensitivity, causing degradation of its mechanical properties. Therefore, during mechanical testing of hydrogen charged samples, a well-defined hydrogen distribution is essential to better understand the influence of hydrogen on dislocation movement and plasticity behavior.

Preferential corrosion of coherent twin boundaries in pure nickel under cathodic charging

PHYSICAL REVIEW MATERIALS, 2019
We describe an investigation of microstructure in pure nickel (Ni) after cathodic charging in an aqueous electrolyte. Intergranular corrosion occurs on the sample surface and takes the form of long trenches along coherent twin boundaries (CTBs): sites ...

Effect of loading mode on blistering in iron submitted to plastic prestrain before hydrogen cathodic charging

, 2017
International audienceTensile tests and simple shear tests have been performed on Armco iron sheets before hydrogen cathodic charging, in order to study the effect of loading mode on blistering of plastically prestrained samples. The experimental results

Analysis of the various processes downstream cathodic hydrogen charging III: Mechanistic issues on charging, degassing and sulfide stress cracking

, 2016
The elementary steps of hydrogen charging and degassing are identified from a combination between reaction orders and acoustic emission, and the higher degassing rate on the H2S side makes the natural permeation in the field still more different from its

Analytical Observation of Cathodic Zinc Deposition in High-Capacity Zinc Oxide Electrodes for Rechargeable Zinc-based Batteries: Influence of the Current Rate in the First Charging

Electrochemistry
The effects of the current rate used during the first charging (pre-charging: so-called “formation”) on the cathodic deposition of metallic zinc (Zn) were analyzed for the high capacity (thick) zinc oxide (ZnO) electrode in rechargeable Zn-based ...
