The article presents the results of studies of the surface layers’ quality (microstructure, microhardness, roughness, and continuity) of BrO10S10 bronze specimens with combined electrospark coatings (CEC). The coatings of three series are investigated: the 1$^{\textrm{st}}$ series prepared without sulfurizing (Ag $\to$ Pb $\to$ Ag і Ag $\to$ Sn $\to$ Ag), the 2$^{\textrm{nd}}$—included a deposition of sulphur in the form of a sulphuric ointment to the surface to be treated before silvering (S + Ag $\to$ Pb $\to$ S + Ag і S + Ag $\to$ Sn $\to$ S + Ag), and the 3$^{\textrm{rd}}$—included the application of sulphuric ointment to the surface to be treated before the next stage of electrospark alloying (S + Ag $\to$ S + Pb $\to$ S + Ag і S + Ag $\to$ S + Sn $\to$ S + Ag). As found, on samples of the 1$^{\textrm{st}}$ series, with an increase in the discharge energy ($W_{\textrm{р}}$), the thickness of the CEC increases from 0.27 to 2.9 mm, while the microhardness is in the range of 8–140 and 130–183 MPa for coatings with lead and tin, respectively, roughness $Rz$ = 8.5–10.0 $\mu$m. For samples of the 2$^{\textrm{nd}}$ series, with an increase in $W_{\textrm{р}}$, the thickness of the CEC increases from 0.19 to 1.3 mm, the microhardness is in the range of 80–180 MPa, and the roughness $Rz$ = 5.5–7.5 $\mu$m. The continuity for all samples is 100%. As shown, the CECs on samples of the 3$^{\textrm{rd}}$ series are destroyed. The CECs formed in the sequence S + Ag $\to$ Pb $\to$ S + Ag and S + Ag $\to$ Sn $\to$ S + Ag are recommended for practical application, if their thickness is sufficient for subsequent technological impact by any known method (blade treatment, non-abrasive ultrasonic finishing, $etc.$).
