METHOD OF MAKING COPPER COATINGS WITH DEVELOPED SURFACE Russian patent published in 2017 - IPC C25D3/38 C25D5/34 B01J37/34 B01J35/10 

FIELD: metallurgy.

SUBSTANCE: electrodeposition process is carried out using mechanical activation of the cathode from sulfuric acid electrolyte with the addition of activator particles inert to the electrolyte in the form of powder with the fraction of 10-30 microns at the concentration of 20-50 g/l, the electrolyte is carefully mixed with the activator mechanically or by air prior to the electrodeposition, then the mixing is stopped and the process of copper electrocrystallisation or electrodeposition is started. The process is performed with intermittent mixing of the activator with the electrolyte in a potentiostatic mode at 50-200 mV overvoltage for 10-20 minutes.

EFFECT: invention provides the ability to create copper defect crystals, coatings and layers thereof having a developed surface.
