This research investigates the use of pulse-reverse voltages on Al ‎‎2219 as a pre-treatment for ZnNi ‎electrodeposition via brush-‎plating. Faraday’s process can employ a neutral and ‎environmentally ‎benign pretreatment electrolyte within a brush-‎plating system for field applications of ZnNi ‎deposition on Al ‎surfaces.‎

Topics:

Advances in Surface Finishing Technology

ZnNi is useful as a hard protective corrosion inhibiting coating for ‎aluminum alloys. In this ‎presentation, we will discuss recent work ‎on the development of a one-step surface pretreatment for ‎the ‎brush electrodeposition of LHE alkaline ZnNi coatings on Al 2219. ‎Coating of the aluminum ‎commonly requires extensive and ‎specialized surface pretreatment processes (such as zincate and ‎‎electrolysis NiP application) prior to deposition, owing to ‎aluminum’s reactive nature and affinity for ‎oxygen. By leveraging ‎pulse-reverse current application, Faraday’s process can employ a ‎neutral and ‎environmentally benign pretreatment electrolyte ‎within a brush-plating system for field applications ‎of ZnNi ‎deposition on Al surfaces.‎
