Neutrino Focusing Horns; required for research on particle ‎accelerators and storage rings, are ‎commonly made of aluminum ‎and coated using electroless nickel. Faraday has demonstrated a ‎‎technology that will provide an alternative direct deposition onto ‎aluminum that reduces the cost, ‎chemical volume and complexity ‎of the process. The technology is adaptable to applications that ‎‎require electrodeposited coatings on passive metals such as ‎aluminum, titanium and stainless steels.‎

Advances in Surface Finishing Technology

This session will describe recent research work on the ‎development of corrosion resistant coatings ‎directly applied to ‎aluminum alloys (6061/4047) after a one-step electrochemical ‎surface ‎pretreatment process. Applying coatings to 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. In this study we will discuss a ‎simple ‎pretreatment process that enables direct deposition of ‎ZnNi, NiP, or Ni coatings onto Al alloys and ‎can dramatically ‎reduce the cost and challenges associated with the surface ‎preparation of Al. ‎Furthermore, we will discuss the ‎corrosion/erosion performance of the Ni, and NiP coatings applied ‎‎directly to 6061 Al and 4047 Al surfaces.‎
