Corrosion Resistance of Fastener Coatings.
Abstract
Coating materials are needed to replace electrodeposited cadmium on steel fasteners for use in high performance aircraft. A study was made to compare corrosion resistance of ten experimental coatings, mostly aluminum-rich types, with cadmium. Several experimental coatings provided high resistance to 5% NaCl salt fog and NaCl-SO2 salt fog exposure tests. Paint adhesion was excellent on all fastener coatings with an epoxy primer/polyurethane topcoat system. Cadmium and the other fastener materials examined in this study varied widely in coating thickness on different fastener surface areas. (Author)
