...) increased as ΔK increased under the same water quality and loading conditions. In SCC tests, the longer the Δt_H, the slower the CGR. On the other hand, it was found that dissolved hydrogen (DH), which lowered the electrochemical potential (ECP), could significantly decrease the CGR in either CF...

... − ) solution with high pH (~ 9 to 11). This type of SCC occurs in a very restricted range of electrochemical potentials (–550 mV vs a saturated calomel electrode [SCE] to ~ –650 mV_SCE). Dominated by film rupture and dissolution, this is the so-called classical SCC. ^1-2 However, several...
