Abstract
The calculation of the surface-induced enhancement of the binding ener gy of hydrogen impurities in transition metals, previously reported fo r close-packed surfaces, are extended to open surfaces in the fee and bcc structures. The effect is found to be stronger for close-packed su rfaces than for open ones. Numerical values for the subsurface bonding energy in Nb and Pd are given, from which changes in the kinetics of hydrogen absorption through specific surfaces are predicted.
