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.

Copper - More Than Just a Metal We Electroplate

Over many years, well-regarded AESF/NASF contributor Jack Dini contributed a series of fascinating columns to Plating & Surface Finishing, under the title Fact or Fiction?.  After his new offering in July, we are happy to offer a second welcome contribution to his output for the NASF, this time on copper.

NASF/AESF Foundation Research Project #121: Development of a Sustainability Metrics System and a Technical Solution Method for Sustainable Metal Finishing: 1st Quarterly Report

This report (1) introduces the new project and (2) covers the first quarter of project work (April-June 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.

NASF Releases PFAS Sampling and Analysis Plan

New Sampling and Analysis Plan (SAP) includes the best practices for collecting and analyzing PFAS samples from surface finishing operations.  

Anodizing

AES Research Project #41: Plating on Anodized Aluminum; Part 3: Pore Structure and Bonding

The effect of anodizing voltage on the adhesion of nickel electrodeposited on anodized aluminum is related to the morphology of the anodic film.  In general, adhesion is a linear function of the applied anodizing voltage.  New data on the initial stages of pore formation during anodizing indicate that: (1) that the growth mechanism during the initial stage (< 10 sec) differs from that during subsequent growth, (2) there is no metallic bonding and (3) electrodeposited nickel coatings typically fill the entire pore.

AES Research Project #41: Part 4: Adhesion Failure of Electrodeposited Coatings on Anodized Aluminum Alloys

An SEM study of peel-test adhesion specimens from plated coatings on anodized aluminum shows that failure can be categorized in three different modes: (1) specimens exhibiting poor adhesion strength, which fail at the anodic film/coating interface; (2) specimens with good adhesion strength, which fail by local fracture of the anodic film and (3) specimens with excellent adhesion strength , which fail when the applied load is greater than the strength of the alloy substrate.  The effect of anodizing parameters and alloy composition on peel test failure are discussed.

Celebrities Who Once Worked in Electroplating

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.

AES Research Project #41: Plating on Aluminum, Part 2: Morphology

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.

AES Research Project #41: Plating on Aluminum, Part 1: A Literature Review

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.
