Sonochemical Electrodeposition of Copper Coatings

Potentiodynamic polarization method was used to study kinetic specific features of the electrodeposition of copper under a sonochemical treatment of a sulfuric acid electrolyte. The working current densities, scattering power of the electrolyte, the structure, microhardness, and luster of the formed coatings were determined depending ultrasonic field power and the presence of a thiourea additive in the electrolyte. It was found that it is advisable to perform the sonochemical electrodeposition of copper from a sulfuric acid electrolyte with addition of 0.003 g dm–3 of thiourea at a current density of 2 A dm–2 and ultrasonic vibration power of 8 W dm–3.
