Session 1: Aerospace/Defense Response to REACh
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.

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.
