Environmentally Friendly Fastener Coating Demonstration
Abstract
Traditionally, steel fasteners have been used with cadmium electroplated coatings followed by a hexavalent chromium rinse. The environmental hazards associated with cadmium and hexavalent chromium are well established and significant legislation has been put in place recently to limit their continued usage. It is critical that suitable replacement technologies be identified that can provide these high performance characteristics in a cost effective manner. Two commercially available fastener finish systems are evaluated in this work for suitability as cadmium replacement options. These include high purity aluminum plating plus cationic epoxy electrocoat, and zinc-rich dip-spin primer plus cationic epoxy electrocoat. The evaluations include lab and field testing on military vehicles.
