Using the methods of scanning microscopy and X-ray photoelectron spectroscopy, the effect of exposure to a powerful nanosecond ion beam on the morphology and chemical state of the surface layer of commercially pure titanium was studied. It has been experimentally established that at a current density of 150 A/cm2, melting of a surface layer with a thickness of ~ 1.5 μm occurs, which confirms the results of theoretical calculations. The interaction of molten titanium with carbon present on the surface in the form of adsorbed contaminants, as well as implanted into the surface layer, leads to the formation of titanium carbide compounds. Keywords: titanium, titanium carbide, pulsed ion beam, ion modification.
