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.

Electro-codeposition of MCrAlY Coatings for Advanced Gas Turbine Applications - 8th Quarterly Research Report
This NASF-AESF Foundation research project report covers the eighth quarter of project work (October-December 2019) on AESF Foundation Research at Tennessee Tech. The objective of the work is to study and optimize the MCrAlY electro-codeposition process to improve the coating oxidation/corrosion performance. In this quarter, the effects of particle density and shape on codeposition were studied. The results show that the shape of the particles plays an important role.

Electrochemical Destruction of Perfluorooctanesulfonate in Electroplating Wastewaters - 1st & 2nd Quarterly Report
This is the first report on a new NASF-AESF Foundation research project dealing with PFAS - a critical issue for the surface finishing industry. The project will study an electrochemical, destructive treatment strategy for the remediation of relevant PFASs in electroplating wastewater. The overall objective is to utilize a cost-effective reactive electrochemical membrane (REM) for the removal of PFAS from synthetic electroplating wastewater.

Electrocodeposition of MCrAlY Coatings for Advanced Gas Turbine Applications - 7th Quarterly Research Report
This NASF-AESF Foundation research project report covers the seventh quarter of project work (July-September 2019) on the AESF Foundation Research project at the Tennessee Technological University. The objective of the work is to study and optimize the MCrAlY electro-codeposition process to improve the coating oxidation/corrosion performance. In this quarter, the effect of the particle size of gas-atomized CrAlY powders on electro-codeposited Ni-CrAlY composite coatings was studied.

This NASF-AESF Foundation research project report covers the 13th and 14th quarters of project work (January-June 2019) on this AESF Foundation Research project at the University of Houston. The activities in this period continued towards calculating an optimum pulse current deposition method to control and mitigate the stress state of chromium thin films. This study should enable development of an effective strategy generally applicable in practice whenever electrodeposition process for crack-free films is demanded.
