Best Plating Practices for the Application of Brush Plated Zinc-Nickel
Brush plating is an industrial electroplating process designed for demanding OEM and repair applications, without the use of an immersion tank. This presentation demonstrates the best practices for brush plating zinc-nickel to meet the ASTM standards of hydrogen embrittlement and corrosion protection. From preparatory steps to the application of a trivalent chromium conversion coating, the proper plating techniques needed to meet the customers’ demanding requirements are discussed.

Nanostructure of Porous Anodic Aluminum Oxide: Advances in Surface Engineering
Porous alumina membranes of anodic aluminum oxide (AAO) are widely used for the fabrication of various nanostructures and nanodevices. Over the last decade, nanowires, nanotubes and nanodot arrays, have been fabricated by the deposition of various metals, semiconductors, oxides and polymers inside the pores of AAO membranes. These structures are produced by changing the anodization conditions, during electrochemically self -ordering of AAO. One can obtain amorphous barrier-type oxides, crystalline barrier-type oxides or amorphous nanoporous oxides, but fabricating binary nanostructures is challenging. Here, we review methods to achieve diverse binary nanostructure arrays, including material, dimension and morphology.

Improved Process Capabilities for Groove Repair
Advanced selective plating techniques have been developed for the challenging application of repairing internal grooves that have experienced severe corrosion. Many groove configurations require uniform, high-thickness deposition of a plated deposit onto any, or all, of the surfaces with a minimal need for intermediate machining steps. This paper demonstrates how a combination of an engineered, wrap-less anode design along with optimized computer controlled operating parameters has led to reduced downtime, high quality and repeatable selective plating repairs.

Novel Post Treatment of Nano-particle Reinforced Metallic Coatings
This paper discusses a novel post-treatment reinforcement process for both electroless and electrolytic nano-composite coatings which further improves the hardness of the coating (+40%), while also improving the ductility of the material. This technology is applicable to commercial baths for a large variety of electrolytic and electroless coatings. Interestingly, post-treated coatings retain performance at higher temperatures, suggesting improved oxide dispersion strengthening effects, potentially offering new coating options for high temperature applications.
