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.

Hexavalent-Chromium-Free Aluminum Sacrificial Paint Validation

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 second of two papers discusses the hexavalent-chromium-free process from the user point-of-view in terms of the process validation work by Rolls Royce Corporation.

Nanostructure of the Anodic and Nanomaterials Nanoparticles in Polyelectrolyte Multilayer-by-Layer (LbL) Films

Microstructure and elemental characterizations have indicated that the finish of a coating with a Layer-by-Layer (LbL) film results in a closely multilayered coating with a smoother surface. In this paper, the principles of assembly are discussed together with the properties of nanoparticles and LbL polymeric assembly essential in building hybrid coatings.

The History of Electroplating and A Historical Review of the Evolution of NASF

The history of electroplating is a curious mixture of mistakes, observations, serendipity and experimental development, enmeshed and entwined with the discovery of electricity in the late 18th century. Join Mr. Nebiolo as he reviews the fascinating history of our industry and its metamorphosis during the last 238 years. He will also provide a brief history of our flagship society, the NASF.

Non-PFAS Wetting Agents for Decorative Chromium(VI) Plating

This article is based on a presentation given at NASF SUR/FIN 2022, in Rosemont, Illinois, in Session 6, Responses to PFAS / PFOA. It follows the case study of three facilities’ conversion from PFAS-containing wetting agents to non-PFAS equivalents, eliminating PFAS and moving forward with a smaller and more sustainable environmental footprint. The journey of conversion from PFAS-containing wetting agents in both chromic-sulfuric etch and hexavalent decorative plating tanks can be complicated and winding due to deep rooted standard industry practices, as well as state and federal regulations. Outlined here is a clear course of action that led to eliminating PFAS from the facilities’ wetting agent strategies.
