The National Association for Surface Finishing (NASF) explains the latest details of the legislative package for the Paycheck Protection Program (PPP) that would reportedly allow more flexibility for surface finishers to spend forgivable loans for payrolls and expenses.
Over many years, AESF/NASF stalwart Jack Dini contributed a series of fascinating columns to Plating & Surface Finishing, under the title Fact or Fiction?. What follows is a welcome addition to his output for the NASF. Still the prolific writer, Jack discusses celebrities (both scientists and non-scientists) who once worked in electroplating.
Originally published in 1980, this paper was the second on AES Research Project #41, plating on aluminum, at the National Institute for Science and Technology. A study of the morphologies of zinc and tin immersion deposits on Al and its alloys showed that zinc formed epitaxial deposits on alloys, as noted on pure Al. Similarities exist between the zincate and stannate processes; in particular, the same crystallography orientations are active in both systems. Comparisons between zinc deposits produced from solutions containing ferric chloride and Rochelle salts and deposits from the same solution without these additions show that ferric chloride plays a fundamental role in the deposition process.
Originally published in 1978, this paper was the first of several on AES Research Project #41, a study of plating on aluminum, at the National Institute for Science and Technology. A review of immersion pretreatments for the plating on aluminum is presented. The zincate pretreatments dominate the literature, but innovations were reported which offer improved adhesion and corrosion performance. Finally, an updated bio on Dr. Lashmore’s work through the years is offered.
Electro-codeposition of MCrAlY Coatings for Advanced Gas Turbine Applications - 9th Quarterly Report
The NASF Research Board has funded a research grant at the Tennessee Technological University, under the direction of Professor Ying Zhang. The objective is to study and optimize the MCrAlY electro-codeposition process to improve the coating oxidation/corrosion performance. In this reporting period, the study studied a sulfur-free fluoborate plating solution. Although the fluoborate solution is sulfur-free and offers high plating rates, the CrAlY powder was attacked by the fluoborate anion. The fluoborate-based plating bath may be suitable for codeposition of more inert particles but not for active CrAlY-based powders.

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.
Crack Formation During Electrodeposition and Post-Deposition Aging of Thin Film Coatings - 13th-14th Quarter Report
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.
Chapter President Paul Skelton says the event brings together a community of metal finishing professionals to promote and advance the industry’s past, present and future.
