Surface segregation in ternary alloys

Surface segregation profiles of binary (Cu–Ni, Au–Ni, Cu–Au) and ternary (Cu–Au–Ni) alloys are determined via Monte Carlo–Metropolis computer simulations using the BFS method for alloys for the calculation of the energetics. The behavior of Cu or Au in Ni is contrasted with their behavior when both are present. The interaction between Cu and Au and its effect on the segregation profiles for Cu–Au–Ni alloys is discussed.
