Preventing Hydrogen Embrittlement: The Role of Barrier Coatings for the Hydrogen Economy
Hydrogen, 2023 Hydrogen barrier coatings are protective layers consisting of materials with a low intrinsic hydrogen diffusivity and solubility, showing the potential to delay, reduce or hinder hydrogen permeation.

Hydrogen-Induced Cracking in CGHAZ of Welded X80 Steel under Tension Load
Metals, 2023 X80 steel is extensively used in hydrogen environments and is susceptible to hydrogen embrittlement (HE). This paper studied the hydrogen-induced cracking (HIC) behavior in the coarse-grained heat-affected zone (CGHAZ) of X80 steel welds, through ...

Review of Characterization on Hydrogen Embrittlement by Micro-Sample Testing Methods
Metals, 2023 Conventional-sized specimens have been well and widely applied in research on hydrogen embrittlement. However, when the limited-size core components (nozzles and valves, etc.) of hydrogen energy equipment are evaluated for service damage, traditional ...
