Abstract
We study the relation between the surface segregation at thermodynamical equilibrium in an alloy A c B 1− c and the kinetics of dissolution of A B or B A . This is possible within a new kinetic model based on the electronic structure: the kinetic tight-binding Ising model. In particular, the existence of a local equilibrium between the surface and the first underlayer is stressed. Some illustrations are given in the particular case of two systems, one presenting a tendency to bulk phase separation and surface layering transitions (CuAg) and the other a tendency to bulk ordering and surface concentration profile transitions (PtNi). The notion of “ surface alloy” is defined in the latter case.
