Investigation of the modified surface obtained by the method of electrospark alloying in liquid ester media for the formation of friction films

The article presents the results of research on obtaining a modified coating by the method of electrospark alloying in liquid ester media intended for use in tribo- conjugation nodes. Tungsten was used as the electrode material used. The elemental composition of the formed coating was determined by scanning electron microscopy. The chemical composition of the formed friction films and the chemical bond in these films were investigated by X-ray photoelectron spectroscopy (XPS). It is established that the formation of boundary films occurs mainly from molecules of the interelectrode medium with the participation of atoms of non-oxidized iron. The thickness of the formed layer in the studied samples ranged from 9 to 40 microns.
