A Study of the Process of Gold Plating from Citrate and Phosphate Electrolytes in the Presence of Modified Detonation Nanodiamonds.

The use of modified detonation nanodiamonds in the most common gold-plating electrolytes—citrate and phosphate—makes it possible to increase microhardness by a factor of about 1.2 and wear resistance from 3.6 times up to that of a practically non-abradable coating, while keeping unchanged the electrolyte formulations, temperature, and current density which are typically used in the conventional technological process. The coating thickness is recommended to be reduced 2- to 3-fold. [ABSTRACT FROM AUTHOR]
