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.

Development of a Novel Hexavalent-Chromium-Free Aluminum Sacrificial Paint
Hexavalent chromium is a known carcinogen, repro-toxin, and mutagen. Its elimination is of high importance to the aerospace industry, which has struggled to find high performing alternatives. Legacy aluminum sacrificial paints have traditionally utilized hexavalent chromium to prevent corrosion and coatings which are equal to or better than have been difficult. This first paper discusses the novel process from the supplier point-of-view.
