An orthogonal experimental methodology was used to study a copper immersion coating on AZ91 magnesium-alloy from a hydrofluoric acid-containing bath. Factors such as hydrofluoric acid concentration, sonication time, chemical etching, and activation process were considered in the design. The analysis of variance on the orthogonal experimental results was performed, resulting in an optimal condition for achieving a uniform copper coating with high coverage. Hydrofluoric acid was found to be an essential component in the copper immersion coating bath and a possible mechanism was suggested to explain its significance in terms of magnesium film destruction and magnesium dissolution.Peer reviewed: YesNRC publication: Ye
