Evaluation of Environmentally Acceptable Protection Schemes for High Strength Steel Fasteners, Tri-Service Committee on Corrosion Proceedings.

Abstract

Initial corrosion testing was done by ARL Materials Directorate in 1991 in a TACOM (Tank/Automotive Command) sponsored study to determine the effects of substituting Zinc or various other coating systems in the place of electroplated Cadmium. In addition to test assemblies utilizing a single coating, mixed assemblies comprised of various coated bolts and Cadmium coated washers/nuts were evaluated. The results were published in a technical report (MTL TR 92-40),1 which contains complete corrosion data and photographic documentation of the corrosion observed throughout the test program for Cd, Zn-Ni, Zn OD (Olive Drab finish), Zn-Co, Sn-Zn, and modified phosphate coatings. This paper will summarize these results, and add data for lVD Al. Three types of lVD Al are compared against the Cadmium and Zn-Ni plating.
