The Benefits of Automated Selective Plating
More companies are relying on the consistency and traceability that automated processes provide, so why would selective electroplating be any different? Selective plating is a method of electroplating localized areas without the use of an immersion tank. Automated equipment has recently been developed for some very challenging applications. Fully customized machines can be designed for repair or OEM applications to apply engineered deposits without the need for operator intervention, changing the perceived notion of a once highly manual operation. This presentation highlights the key benefits of automating the selective plating process.

The Move Toward Effective Colorless Zinc-Nickel Passivates
Zinc-nickel passivation continues to be a robust method of extending the corrosion protection of electroplated substrates, as well as providing a visually appealing finish. In the past, clear passivation for zinc-nickel did not offer high levels of corrosion protection. This paper discusses both the mechanism by which passivate films are colored as well as the development of a clear, colorless zinc-nickel passivate that achieves good corrosion protection.

NASF/AESF University Funded Research Transitioned to Industry: Practical Performance Improvements in Functional REACH-Compliant Trivalent Chromium Plating
This paper shows information learned from a NASF/AESF Foundation Research grant which has led to successful application. The work at the University of Houston (UH) is discussed – a technique developed to perform in-situ analysis of the stress of the chromium deposit from a REACH-compliant trivalent chromium electrolyte. An understanding of crack formation during plating has led the way to a means to avoid it. Faraday Technology Inc. scaled-up and optimized the same process through support from the U.S. Army. The results enabled significant chromium coating performance enhancements, matching the wear index of conventional Cr deposits from hexavalent baths.

Decorative Trivalent Chromium Deposits Applied by Barrel Electroplating
With the wide acceptance of the benefits of decorative trivalent chromium plating, there is a growing demand to successfully adapt this technology to barrel plating. Traditionally, trivalent chromium deposits were not commercially viable using barrel electroplating. Factors such as barrel design, cathode contact, anode placement and current density must be considered when providing a trivalent chromium barrel electrodeposit. This presentation outlines trivalent deposits applied in a barrel and examines variables in operating and electrolyte compositions.
