Abstract
Hydrogen embrittlement testing using cathodic hydrogen charging is directly relatable to structures containing gaseous hydrogen if the hydrogen fugacity is known. The hydrogen fugacity, fHc, was evaluated by comparing the hydrogen concentration after cathodic charging with the hydrogen concentration in equilibrium with hydrogen gas: fHc0.5 = 6.11 i0.5 + 10.9 for cathodic hydrogen charging X65 D in 0.10 M NaOH at a current density of i. The hydrogen concentration in equilibrium with gaseous hydrogen in X65 D, CHg, was evaluated from literature values and hydrogen gas-phase permeation results: CHg = 0.0062fHg0.5 + 0.0355, where fHg is the hydrogen gas fugacity.
