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

Abstract

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.
