| Abstract Scope |
Faraday will describe our recent work on the development of corrosion resistant coatings directly applied to aluminum alloys (6061/4043) after one-step electrochemical surface pretreatment process. Conventional aluminum coating application processes commonly require extensive surface pretreatment processes 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 onto Al alloys and can dramatically reduce the cost and challenges associated with the surface preparation of Al. Furthermore, we will discuss the corrosion performance of the Ni, and NiP coatings applied directly to 6061 Al and 4043 Al surfaces. The technology is adaptable to applications that require electrodeposited coatings on passive metals such as aluminum, titanium and stainless steels. |
