Abstract:Iron-nickel contact surfaces subjected to ion-induced modification are studied by AES, XPS and AFM. The corrosion and erosion resistance of the modified contacts is associated with features of the surface topography, and with the formation of iron and nickel nitride layers. The fine energy structure of the atomic state is revealed. Ion irradiation of the contact surfaces yields the formation of pores and cones.
