The paper presents the results of obtaining doped aluminum-titanated coatings using the self-spreading high-temperature synthesis (SHS) technology on copper alloys. The proposed method of hardening contributes to a significant increase in the corrosion resistance of copper alloys in a 3% solution of sodium chloride increases by 1.5 ... 1.8 times, as well as an increase in the scale resistance of brass and bronze in 8—12 times compared with non-titanium. Differences in the quality of the surface, structure, phase, composition, microhardness and the content of alloying elements in the diffusion layers on copper alloys are determined by the temperature of the process, the aging time and the composition of the SHS mixture.
