NASF Report: October 2020
This month’s NASF content includes two papers, one discussing a new electrodeposition pretreatment process and the other updating readers on ongoing research at Wayne State University.
This month’s National Association for Surface Finishing (NASF) content takes the form of two papers. Read the descriptions and find links below:
A Novel Pretreatment Process for Direct Electrodeposition onto Aluminum Alloys

This paper discusses a novel pretreatment process for direct electrodeposition nickel-phosphorus (NiP) and nickel (Ni) from commercial electrolytes onto aluminum (Al) alloy (T6061) surfaces without the need for zincate or stannate pretreatment processes. The authors compare the coatings’ properties to conventional commercially applied electroless NiP using conventional pretreatment processes.

NASF/AESF Foundation Research Project #121: Development of a Sustainability Metrics System and a Technical Solution Method for Sustainable Metal Finishing: 2nd Quarterly Report
Prof. Yinlun Huang, Wayne State University, Detroit, Michigan, USA
The NASF Research Board has funded a research grant at Wayne State University on sustainability in the surface finishing industry, under the direction of Professor Yinlun Huang. The objective of the work is to create a surface-finishing-specific sustainability metrics system to measure economic, environmental and social sustainability and use it to identify problems and generate a road map for sustainability performance improvement and profitability assurance in plants. The Board invites readers to contact Dr. Huang to identify plating shops willing to participate in this program.

In our first paper this month, featuring the latest work from AESF/NASF Research, the rotating cylinder Hull cell (RCH) was used to study the behavior of a Ni-Mo-W plating bath. Originally published in 1993, this second paper outlines the basic concepts and work behind the development of the RCH cell.
Evaluation of Atmospheric Corrosion on Electroplated Zinc and Zinc-Nickel Coatings by Electrical Resistance (ER) Monitoring
This paper is a peer-reviewed and edited version of a presentation delivered at NASF Sur/Fin 2013 in Rosemont, Ill., on June 12, 2013.
The Behavior of Intermetallic Compounds in Aluminum during Sulfuric Acid Anodizing Part 2: Al-Cu, Al-Mg, Al-Si, Al-Ti, Al-Fe-Si, Al-Zn-Mg Alloys
The 1971 Carl E. Huessner Gold Medal Award was given to J. Cote and co-workers for the Best Paper appearing in Plating or the AES Technical Proceedings in 1970. Actually a two-part paper beginning in 1969, the second installment of the paper from 1970 is republished here in a series on the AES/AESF/NASF Best Paper Awards. Their work presents very important work on how the anodizing process reacts with the other materials alloyed in with commercial aluminum grades.
