Anodic dissolution of AgPd alloys in 12 M LiCl is being investigated using Auger electron spectroscopy and coulometry for the determination of Pd surface enrichment. Under steady state conditions Ag dissolves selectively in alloys containing < 5 Y0 Pd, while both components dissolve in stoichiometri
Equilibrtum surface segregation concentrations have been measured for tm diluted in aluminmm wrth bulk concentrattons of about 2 x 10-s atom per aluminium atom, between 623 and 893 K. MacLean's model fits the experimental results well and gives a segregatton energy q,, = -77 kJ mole-' between 293 K
