Abstract: The efficient method of improving diffusion of more noble metal through barrier layer created during electrochemical deposition process, by means of acoustic streaming was investigated. The results obtained from the experiments demonstrates the possibility of controlling the amount of liquid injected to the vicinity of cathode by the change of acoustic intensity. This results in accomplishing the controlled migration inside barrier layer and thus the inspecting of the mass of more noble metal in the plated alloy. The Schlichting type of acoustic streaming was mostly used in investigation.
