CONTRIBUTION OF EXAFS-LIKE TECHNIQUES TO THE DETERMINATION OF LOCAL ORDER: APPLICATION TO TRIBOLOGY: The determination of local order at atomic scale becomes more and more fundamental for understanding superficial phenomena such as tribology and catalysis. Among a few techniques available in this field, we are only concerned with the EXAFS-like ones (EXAFS, SEXAFS, EXELFS, SEELFS, etc.). The difficulties appearing all along the numerical treatment of such spectra are carefully analysed and a methodology is proposed in view to obtain reliable radial distribution functions. Some applications of these techniques are presented in two fields connected with tribology: friction induced amorphisation in high vacuum and characterization of interfacial solid bodies created during a wear process including an antiwear additive.
