A new theory for the kinetics of surface segregation in binary alloys is proposed, which takes into account the concentration in the subsurface layers. This more realistic segregation profile is derived within the regular solution pair‐bonding model. The surface composition as a function of time is determined analytically and it is in qualitative agreement with the experimentally observed behaviour.
