NASF/AESF Foundation Research Project #120: Electrochemical Destruction of Perfluorooctanesulfonate in Electroplating Wastewaters – 7th & 8th Quarter Report
This NASF-AESF Foundation research project report covers the seventh and eighth quarters of project work (October 2021-March 2022) at the University of Illinois at Chicago. The major activities reported are: (1) to investigate 6:2 FTS oxidation, a common replacement compound for PFOS in the electroplating industry, and (2) PFAS oxidation in both a wastewater sample procured from an electroplating facility and in synthetic solutions.

Non-PFAS Wetting Agents for Decorative Chromium(VI) Plating
This article is based on a presentation given at NASF SUR/FIN 2022, in Rosemont, Illinois, in Session 6, Responses to PFAS / PFOA. It follows the case study of three facilities’ conversion from PFAS-containing wetting agents to non-PFAS equivalents, eliminating PFAS and moving forward with a smaller and more sustainable environmental footprint. The journey of conversion from PFAS-containing wetting agents in both chromic-sulfuric etch and hexavalent decorative plating tanks can be complicated and winding due to deep rooted standard industry practices, as well as state and federal regulations. Outlined here is a clear course of action that led to eliminating PFAS from the facilities’ wetting agent strategies.

PFAS Legislation Introduced That Specifically Targets Surface Finishing
Legislation was recently introduced again in Congress that would require EPA to issue wastewater discharge limits for PFAS for electroplating and metal finishing source categories. Among other impacts, the measure would accelerate the PFAS rulemaking on which NASF is already working with EPA.

Developing Standardized Testing for Trivalent Chromium Thickness: A Progress Report
The industry shift toward trivalent decorative chromium plating and away from hexavalent highlights a need for testing standards. As Chair for ASTM B08.10 Subcommittee on Test Methods for Metallic and Inorganic Coating, Mark Schario is leading the committee’s focus on developing standardized testing for trivalent chrome thickness. This presentation provides information on the initiative, testing methods and variables, initial data on thickness comparison and alloy composition, and summary of input and extended lab testing.

Improving the Wear Performance of Functional Trivalent Chromium Plating Via Pulse-Reverse Electrodeposition
This paper covers work on improving the wear performance of a functional chromium coating from a trivalent chromium plating bath. Wear resistance is a critical aspect of chromium coatings when used in components of both ground-based and aerospace vehicle systems. Traditional hexavalent chromium coatings have shown exceptional wear resistance in these applications, while the wear resistance of trivalent chromium coatings has been less satisfactory. Using pulse-reverse electrodeposition to control various characteristics of the chromium coating, the wear performance of trivalent chromium plated panels could be improved. A multivariate regression model of the electrodeposition conditions shows that bath chemistry parameters within the range of viable plating are not a large contributor to the variance in wear performance, while the roughness and size of macro-cracks is very important for wear-related applications. The multivariate analysis approach undertaken in this study may find potential applications in broad areas of the plating and finishing industry.

Modeling and Simulation for the Finishing Industry - the 55th William Blum Memorial Lecture
As Dr. Keith Legg, 2019 recipient of the NASF Scientific Achievement Award, watched the changes in industry over the past decade or so, he has seen modeling and simulation move from one industry to another. Seeing how and where it is used elsewhere, he concludes that modeling could be more widely and profitably used in the surface finishing industry. In his Blum lecture, he discusses how modeling for surface finishing is a recognized approach today. It is proving to be very useful for plating and some finishing processes and is finding new uses as it develops, but there is a lot to learn. The aim is to make modeling a standard, integrated approach to coating development and corrosion protection.
