The equilibrium surface segregation of Ag to the low‐index surfaces of Cu single crystals is presented. It is found that the close‐packed surface of the (111) orientation allows a high interaction parameter resulting in a discontinuous transition in the surface concentration against temperature, as well as a step in the segregation kinetics. In contrast, the rougher surfaces of the (110) and (100) orientations yield smaller interaction parameter values and a smooth transition in surface coverage against temperature is observed.
