In the article, the results of a local X-ray microspectral analysis of running-in sulphide combined electrospark coatings (CECs) of bronze parts are presented. The coatings, obtained in the sequences S + Ag $\to$ Pb $\to$ S + Ag and S + Ag $\to$ Sn $\to$ S + Ag, are investigated. As established, the CECs are characterized by the presence of metal elements consisted in the electrode-tools (Ag, Pb, and Sn). In coatings that include lead, with an increase in the discharge energy upon alloying with both silver and lead, the diffusion zone of sulphur increases up to 90, 135, and 200 $\mu$m, respectively. Sulphur is distributed unevenly along the layer depth and its concentration is 1.59–3.3%. When a CEC is formed on a sample coated as S + Ag $\to$ Pb $\to$ S + Ag, its thickness reaches 700 $\mu$m. Sulphur is found on the surface and in a depth of up to 50 $\mu$m, as well as in the transition zone at a distance of $\cong$650 microns from the surface. With an increase in the discharge energy, in the samples coated as S + Ag $\to$ Sn $\to$ S + Ag, the thickness of the applied CEC reaches 1.05 and 1.310 mm. Sulphur is found on the surface, its diffusion zone stretches for 200 $\mu$m from the surface, and in the transition zone—for $\cong$100 $\mu$m.
