Segregation process in binary alloys (CuPd, CoPd, AuNi) is investigated by X-ray photoelectron spectroscopy (XPS), auger electron spectroscopy (AES) and elastic peak electron spectroscopy (EPES) using the line shape analysis and the fyzzy k-nearest neighbour (fkNN) rule. Qualitative and quantitative results of the fkNN line shape analysis remain in agreement, indicating Pd and Au surface segregstion. The method investigates the values of mean escape depth (MED) and mean penetration depth (MPD) depending on selected electron kinetics energies (KE) in the range between few to several Angstroms. New application of the fkNN rule for EPES was shown.
