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. Access and print the full paper on the second quarter work at http://gbm.media/NASF20Dec2.

Mechanical Properties of Electroformed Metals
In 1996, the AESF held its highly regarded electroforming course, prepared by Ron Parkinson for presentation by The Nickel Development Institute (NiDI) and the AESF. What follows is a slightly modified excerpt, specifically on the mechanical properties of electroformed metals. Much of this information has withstood the test of time, and gives a perspective of this technology at the turn-of-the-century.

Development of a Sustainability Metrics System and a Technical Solution Method for Sustainable Metal Finishing: AESF Research Project #R-121, 6th Quarterly Report
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. In this report, a benchmarking study of five plants was undertaken to illustrate how the sustainability assessment works.

The Adhesion of Electrodeposits to Plastics
The 1966 Carl E. Huessner Gold Medal Award was given to Dr. Edward Saubestre and co-workers for Best Paper appearing in Plating in 1965, and their paper is republished here in a series on the AES/AESF/NASF Best Paper Awards. This paper is a comprehensive treatise on the Jacquet peel test, a primary test method for determining adhesion on plated plastics.
