Competitive segregation of impurities on the surface of polycrystalline copper
The competitive segregation of sulfur, carbon, and phosphorus on the surface of polycrystalline copper and the segregation kinetics of sulfur in the temperature range 675–875 K have been investigated by Auger electron spectroscopy. The equilibrium segregation energies of impurities and the sulfur diffusion parameters in the near-surface region of copper with a thickness d ≤ 5 μm have been calculated on the basis of the experimental data.
