Composite electrochemical coatings (CEC) deposited from three basic gilding solutions after addition of 0.1–10 g/l of three UDD modifications were studied. The UDD content of in the CEC was varied in the range of 0.2–0.8% depending on the electrolyte composition, the UDD concentration and modification. Microhardness of the CEC is found to increase by 50–70% due to UDD and the microhardness dependence on the UDD concentration may be monotonic or sharp, depending on the modification used. We suggest an effective electrolyte composition with less than 3 g/l of the best UDD modification. Composite electrolyte is characterized by high stability in exploitation, high colloid stability of UDD zol, and good physical, mechanical, protective, and decorative properties of CEC. The coating has a microhardness of 1.5–1.8 GPa, a relative wear resistance of 1.5–2.3, as compared to samples containing no diamond. An average thickness of the continuous layer (on polished substrate or a glance Ni interlayer) is 0.15–0.2 µm.
