Electro-codeposition of MCrAlY Coatings for Advanced Gas Turbine Applications - 11th Quarterly Research Report

The aim of this research is to seek a sulfur-free plating solution for electro-codeposition of (Ni,Co)-CrAlY composite coatings. In this quarter, a sulfur-free, all-chloride plating solution was investigated to lower the sulfur content in the Ni-Co coating matrix. Optimized bath composition and the use of a wetting agent are critical to good results.

NASF/AESF Foundation Research Project #121: Development of a Sustainability Metrics System and a Technical Solution Method for Sustainable Metal Finishing: 2nd Quarterly Report

This report covers the second quarter of project work (July-September 2020) on this project at Wayne State University in Detroit. The objective is to help metal finishing plants to conduct a self-managed sustainability assessment and identify technical solutions for sustainability performance improvement. The reader is invited to contact Dr. Huang in identifying plating shops willing to participate in this program.

A Novel Pretreatment Process for Direct Electrodeposition onto Aluminum Alloys

This paper discusses a novel pretreatment process for direct electrodeposition nickel-phosphorus and nickel from commercial electrolytes onto aluminum alloy (T6061) surfaces without the need for zincate or stannate pretreatment processes. These coating properties are compared to conventional commercially applied electroless (NiP) using conventional pretreatment processes.

Understanding the Anodic Oxide Finish – The First Commercially Available Nanoscale Coating

Dr. Jude M. Runge is the 2020 recipient of the NASF William Blum Scientific Achievement Award. The COVID-19 crisis and the cancellation of SUR/FIN 2020 have affected the timing of the formal award and her delivery of the William Blum Lecture. To honor her properly now, it is timely to publish one of her earlier papers, showing the caliber of her work. Here, she notes that nanomaterials, nanotechnology and nanoprocessing are the marketing buzzwords for the 21st century, stressing that, after all, conventional anodizing processes yield a nanoscale finish. Armed with this knowledge, the ease, reliability and reproducibility of the anodic finish enable insights into new applications.

An Introduction to Fundamental Research on the Mechanism of the Electrodeposition of Metals

From time to time, it has been our intent to present seminal papers from past issues of NASF/AESF journals that are of such significance that, decades later, they bear another look. As Einstein is associated with relativity, Drs. Conway and Bockris are synonymous with theoretical electrochemistry. This paper is in large measure, the result of Project #16, and, as the authors modestly describe it, is “an attempt to describe to the electroplater who understands the basic ideas of electrochemistry, what is being done in research on fundamental electrode processes.” This “attempt” did rather well.

Thermal Aging Effects Between Thick-Film Metallizations and Reflowed Solder Creams

Originally published as S.J. Muckett, et al., Plating and Surface Finishing, 73 (1), 44-51 (1986), this paper was awarded the 1987 AESF Gold Medal for Best Paper published in Plating and Surface Finishing in 1986. With the passage of time, Pb-containing solders have been found to have issues regarding toxicity and health. Nonetheless, the work, methodology and results discussed here remain valuable from a research standpoint.
