Hindrance of Hydrogen Effusion from Steel by Coatings and Layers
A normalized hindrance factor R (0 > R > 1) is defined to range the retarding effect of hydrogen effusion exerted by different coatings and layers at the hydrogen exit side of unilateral charged steel membranes. Hindrance factors derived from H-permeation measurements were established for electrochemically deposited palladium, copper, nickel and zink coatings and chemically deposited Ni-P3, Ni-P12 and Ni-Sn2-P9 coatings. The results are compared with the hindrance effect of oxide layers formed on the steel surface by exposure to moist air.
