The Influence of Cathode Surface Velocity on Friction Aided Jet Electrodeposition

摘要

In friction aided jet electrodeposition (FAJED), nozzle outlet width, flow of electroplating solution passing through the nozzle, and the distance between nozzle and cathode could influence the flow field on the cathode surface. In this research, a flow field mathematical model of FAJED was constructed using FLUENT to simulate the velocity on the cathode surface and investigate the influence of cathode surface velocity on the quality of nickel film produced experimentally. Results illustrated that in the area influenced by deposition on the cathode surface, moderate and well-distributed velocity on the cathode surface was conducive to the production of low-defect count nickel films. Combined with the friction of free particles on the deposition layer, moderate velocity and its even distribution on the cathode surface were chosen to obtain flat, compact deposition layers and process rotational parts.
