Hexavalent-Chromium-Free Aluminum Sacrificial Paint Validation
Hexavalent chromium is a known carcinogen, repro-toxin and mutagen. Its elimination is of high importance to the aerospace industry, which has struggled to find high performing alternatives. Legacy aluminum sacrificial paints have traditionally utilized hexavalent chromium to prevent corrosion and coatings which are equal to or better than have been difficult. This second of two papers discusses the hexavalent-chromium-free process from the user point-of-view in terms of the process validation work by Rolls Royce Corporation.

NASF/AESF Foundation Research Project #122: Electrochemical Approaches to Treatment of PFAS in Plating Wastewater - 6th Quarterly Report
The NASF-AESF Foundation Research Board has selected a project on addressing the problem of PFAS and related chemicals in plating wastewater streams, studying PFAS destruction via electrooxidation and electrocoagulation. This sixth quarter report covers the continued assessment of eight perfluoroalkyl acids PFAAs most commonly found in wastewaters, by electro-oxidation with a Magnéli phase Ti4O7 anode across a range of anodic potentials in solutions, exploring the reaction mechanisms. To summarize, the PFAAs start to exhibit degradation behavior when the anodic potential reaches a level where water oxidation occurs, suggesting that the hydroxyl free radicals generated via water oxidation play a role in PFAA degradation.

This NASF-AESF Foundation research project report covers the tenth quarter of project work (July-September 2022) at Wayne State University in Detroit. This report period covered the development of a significantly enhanced sustainability performance improvement methodology, which (i) allows the evaluation of any number of technology candidates, and (ii) identifies optimal solution(s) through assessing the combined benefits obtained by adopting multiple technologies under various design, manufacturing, cost and technical constraints. The methodology was successfully tested using the data from the five plating facilities.
